Other morphological features, although not included in the diagnostic criteria, should also be considered when determining the presence of a polycystic ovary. The evaluation of the S/A ratio can differentiate between PCOS and control or multifollicular women with both a sensitivity and a specificity of 100%. At this stage, however, PCOS remains the term that is widely known and used. Polycystic ovary syndrome (PCOS) is the most frequent disorder of ovarian function in women of reproductive age (Franks, 1989). However, the role of ultrasound finding of polycystic ovary in the diagnosis of PCOS is under considerable debate. Pituitary-ovarian response to the gonadotrophin-releasing hormone-agonist test in anovulatory patients with polycystic ovary syndrome: predictive role of ovarian stroma. Setting: To evaluate whether some ultrasound parameters of ovarian morphology can discriminate between control women and patients with polycystic ovary syndrome (PCOS). The ovarian volume is calculated by 2D (two-dimensional) ultrasound using the formula for a prolate ellipsoid: volume = π/6 × length × width × thickness of the ovary ( Fig. Transvaginal ultrasound guided ovarian stroma hydrocoagulation (TOSH) in an office setting seems to be a safe, economic and practical procedure that is acceptable by the patients. Unstimulated polycystic ovaries are seen with multiple small follicles located around the more dense ovarian stroma. The 2003 Rotterdam consensus ultrasound criteria of polycystic ovarian morphology (PCOM) proposed the presence of ≥12 follicles measuring 2–9 mm in diameter and/or increased ovarian volume (>10 cm 3 ) in a single ovary or both ovaries . What are sex cord stromal tumours? Ovarian torsion is the fifth most common gynecologic surgical emergency (,1). Heterogeneous appearance of the ovarian stroma (B) secondary to edema is a classic finding of torsion but is often absent, especially in cases of prolonged symptoms. Sao Paulo Med J 2000; 118(1):17-20. None. In this article, we discuss and illustrate the normal appearance and arterial flow … It is recognized that not all polycystic ovaries will be enlarged to this size or greater . The lower discriminatory power of the ovarian volume may reflect the greater likelihood of overlap among controls and PCOS patients . The stromal area, stromal/total area ratio (S/A), stromal volume, and stroma/total ovarian volume ratio were found to be significantly higher in PCOS patients than controls . Which imaging technique should we use in the follow up of gynaecological cancer? Main outcome measure(s): They are usually described by as thin‐walled, unilocular or multilocular, and at times septated cysts with scant blood flow and no solid components. Cystic struma ovarii: a rare presentation of an infrequent tumor. However, the average ovarian volume was similar in postmenopausal subjects with PCOS and controls, thereby suggesting a greater decrement in the volume change in women with PCOS in transition to menopause . Ovarian stroma differs from typical connective tissue in that it contains a high number of cells. Furthermore, Webber et al. Hyperandrogenic anovulation has been proposed as a more accurate and potentially less confusing term, as the ovarian feature is of multiple follicles and not cysts 13. USA.gov. Retrospective data analysis. The high prevalence of the polycystic ovary has further reduced the importance of the ultrasound criteria and raised doubts on its precision. The ovarian stroma appears hyperechogenic (stromal score = 2). The objective of this study was to determine whether ovarian stromal ech … HHS 3 A). Efforts in establishing an objective evaluation index of the follicle distribution pattern may help provide insights into the pathophysiology underlying the classic “string-of-pearls” appearance of a polycystic ovary. Recently, lower cutoff values have been proposed by other researchers ranging from 6.4 to 7.0 mL . Ovarian follicles typically achieve a size of 2 to 3 cm before ovulation. Would you like email updates of new search results? compared the number of follicles categorized by different size ranges (2–5 and 6–9 mm) in the ovaries of PCOS patients and normal controls. Follicle number, not assessments of the ovarian stroma, represents the best ultrasonographic marker of polycystic ovary syndrome. It could be used at the bedside, is low cost, lacks radiation, and directly evaluates both ovarian anatomy and perfusion. Early recognition and restoration of blood flow are important to avoid irreversible ovarian damage. Objective: The ultrasound imaging allows the identification of antral follicles, which are characterized by anechoic cystic structures in the ovary. The 2014 AEPS guidelines recommend that the threshold of follicle number per ovary (FNPO) be increased to 25 with the technology available for optimal resolution (mainly transducer frequency ≥8 MHz) . The new cutoff value was based largely on two studies using the receiver operating characteristic (ROC) curve analysis. Takahashi et al. Fertil Steril. NIH The clinical triad they described later became the basis for PCOS diagnosis . doi: 10.1530/REP-19-0501. In the latter study, the cutoff value is 25 follicles if women with isolated PCOM were included in the control group. Hormonal studies can identify abnormalities that have led to a high level of testosterone. You will also be asked if you’re having any symptoms, when they started, and how long you've had them.  |  Since the widespread use of transvaginal ultrasound to diagnose polycystic ovary syndrome (PCOS), a cardinal feature has been shown to be the presence of a bright, highly echogenic stroma. teratoma. Numerous small cysts occupy the entire ovarian parenchyma. Monitoring of ovaries during stimulated cycles, egg retrieval and assessing the early development of the implanted gestation are but a few of the techniques that could not be done without ultrasound assessment. 3 B). Cut-off values have been defined for ovarian volume (13.21 mL), area (7.00 cm2), stroma (1.95 cm2), and S/A ratio (0.34). eCollection 2017. Baillieres Clin Endocrinol Metab. Volunteers women in an academic research environment. In adult women, a linear pattern of decline was also observed in follicular number and anti-Müllerian hormone (AMH), both remaining higher in subjects of PCOS compared to the adult controls at all ages . With the improvement in resolving power, antral follicles of diameter <2 mm, which have escaped detection previously, can be visualized by modern ultrasound equipment ( Fig. More recently, transvaginal ultrasound examination of ovarian morphology has been used to help make the diagnosis. This results in the counting of more antral follicles and thus a major but artificial increase in the prevalence of PCOM in normal populations. There is, however, a paucity of data for the ovarian morphology in normal and PCOS adolescents. These include enlarged ovary size, multiple small follicles of similar size, increased ovarian stromal volume and echogenicity, peripheral distribution of the follicles, and higher stromal blood flow. Ultrasound identification of the presence of polycystic ovarian morphology (PCOM) has been recognized as a component of PCOS diagnosis. Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting female fertility (Kousta et al., 1999). The identification of PCOS is based on clinical findings that are heterogeneous and highly variable, which makes it challenging to establish the diagnosis. Although normal ovarian findings and ultrasound technique is more thoroughly discussed in Chapter 26, a few observations unique to the ovary bear additional mention here (Fig. The ovarian volume increases through childhood, achieves its maximum volume shortly after puberty, and declines significantly with each decade of life from age 30 to age 70 . While the accuracy of the updated threshold awaits further validation, it provides a new starting point for future PCOS studies. In PCOS, follicular growth is arrested at the antral follicle stage, thereby resulting in excessive antral follicle counts (AFCs). Editor’s Note: Within 8 years of menarche, the presence of many follicles within the ovary is generally considered a normal finding and ultrasound should not be used to diagnose PCOS (Dewailly, 2011; Lujan, 2013; Teede, 2019). Ultrasound is certainly the first-step imaging modality in the diagnosis of ovarian torsion. Patient(s): However, there are some conflicting reports that did not find any significant difference in these indices between the PCOS subjects and controls . The arterial RI derived from the spectrum of ovarian stroma and uterine arteries on each side were calculated separately.  |  1997 May; 16(5):355-8. This type of cancer is more prevalent in women over the age of 50, but roughly 5% of ovarian stromal tumors form in young girls. Best Practice & Research: Clinical Obstetrics & Gynaecology Volume 37. The different patterns of follicle distribution with the ovary may reflect different pathophysiological process of disturbed folliculogenesis . J Menopausal Med. Your doctor will likely do a pelvic exam to check for an enlarged ovary or signs of fluid in the abdomen (which is called ascites). Despite the challenge for standardization, the studies of ovarian stromal blood flow are warranted to investigate and clarify the role of vascular changes in the pathogenesis of PCOS and OHSS. The hyperechogenic stroma is less pronounced a b 97/071 Color Doppler and hormone correlations with PCOS Battaglia et al. According to the normative model developed by Kelsey et al., in the average case, the ovarian volume rises from 0.7 mL (95% confidence interval (CI) 0.4–1.1 mL) at 2 years of age to a peak of 7.7 mL (95% CI 6.5–9.2 mL) at 20 years of age with a subsequent decline to about 2.8 mL (95% CI 2.7–2.9 mL) at menopause and smaller volumes thereafter . 2 A). The criterion of >12 follicles per ovary for diagnosis becomes obsolete. 30-1). Swanson et … The women with PCOS were found to reach menopause 2 years later than the normoovulatory women . Diagnosis of PCOS in adolescent girls should not be based on ultrasound imaging of a high number of ovarian follicles, as there is a high incidence of healthy young women with multifollicular ovaries. In 1935, Stein and Leventhal reported a case series of seven women characterized by oligomenorrhea or amenorrhea, hirsutism, and enlarged bilateral cystic ovaries found at laparotomy . (b) General cystic pattern. Further ultrasound studies of different follicle cohorts, which may be facilitated by 3D technique, are warranted to substantiate the hypothesis of intrinsic aberrant folliculogenesis in PCOS patients. We have demonstrated significant differences in 3D ultrasound parameters of the ovarian stroma in women with and those without PCOS, as well as amongst women with different phenotypic expressions of the disease 60. The results may be explained by folliculogenesis disorders: excessive early follicular growth and/or follicle arrest . The ovarian morphology in adolescence is elucidated. The ultrasound features of the polycystic ovary in adults are presented. US features of ovarian torsion include a. unilateral enlarged ovary, uniform peripheral cystic structures, a coex-. Stromal cells are among the three most common cell types to be affected by ovarian cancer; however, stromal tumors represent only about 1% of all ovarian cancers. J Ultrasound Med.

The morphological features of the ovaries in women with polycystic ovary syndrome (PCOS) have been well described by ultrasound imaging technology. Conclusion(s): Eighty amenorrheic or oligomenorrheic women and 30 normal ovulatory control participants. Intervention(s): According to the pattern of change in ovarian volume with age found in PCOS patients and normal population, careful consideration would be given when using the threshold (>10 cm 3 ) to diagnose PCOS in adolescence or in women over the age of 40 years . If the local norms are not available or the image quality does not allow a reliable estimate of FNPO, the existing volume threshold (>10 cm 3 ) can be used conservatively . A longitudinal study of the ovarian volume in PCOS patients showed that the decrease in ovarian volume with age was less pronounced in premenopausal women with PCOS. Classification of normogonadotropic infertility: polycystic ovaries diagnosed by ultrasound versus endocrine characteristics of polycystic ovary syndrome. reported that the FNPO threshold of 26 follicles was the best compromise between sensitivity (85%) and specificity (94%) to distinguish women with PCOS from the normal controls . Similarly, the stroma/total ovarian volume ratio was reported as the most accurate predictor of hyperandrogenemia and hirsutism . Using hig… Fertil Steril. Prevention and treatment information (HHS). However, heightened awareness and suspicion of this condition are needed for timely intervention. istent mass within the affected ovary, free pelvic fluid, lack of arterial. The aim of this article is to review the updated guidelines and current opinions on the sonographic features of ovarian morphology for clinical practice and further research. The evaluated ultrasound criteria of PCO were as follows: the presence of 12 or more 2–9-mm ovarian follicles; a peripheral distribution of ovarian follicles; an ovarian volume of more than 10 cm 3 and a highly echogenic ovarian stroma . The sonographic finding was supported by the evidence from an experimental study of histological ovarian sections that ovaries from PCOS showed a twofold increase in blood vessel density in both superficial cortical stroma and deep cortical stroma with respect to the age-matched controls . These include enlarged ovary size, multiple small follicles of similar size, increased ovarian stromal volume and echogenicity, peripheral distribution of the follicles, and higher stromal blood flow. reported that androstenedione was significantly higher in the GCP than the PCP and the LH/FSH ratio was significantly higher in the PCP than the GCP. The non-PCOM women with oligoamenorrhea had signs of less severe endocrine disturbance and 33% of them had normal LH, normal LH/FSH (follicle-stimulating hormone), and androgen levels, thereby suggesting a potential hypothalamic cause of amenorrhea . We evaluated ovarian volume, area, stroma, and the stroma/total area (S/A) ratio by use of transvaginal pelvic ultrasound; and we assayed serum levels of gonadotropin, androgen, and estradiol during the early follicular phase (days 2 to 5) of the menstrual cycle in regularly cycling controls and on a random day in amenorrheic patients. 1996 May;7(5):335-41. doi: 10.1046/j.1469-0705.1996.07050335.x. 5. Romualdi D, De Cicco S, Busacca M, Gagliano D, Lanzone A, Guido M. J Endocrinol Invest. In addition, polycystic ovaries are common in young healthy women with a prevalence of 20–30% in women younger than 36 years . It is hypothesized that there are intrinsic differences in folliculogenesis between PCOS ovaries and normal ovaries . It is not possible to define the ovary as “normal” or “polycystic” distinctly by a single cutoff value which itself will certainly be renewed as spatial resolution of ultrasound continues to improve. tissue (e.g. The diagnostic dilemma would remain unsolved until we gain a better understanding of the pathophysiological changes in the entity of patients with PCOM and anovulation. A two- to threefold increase in the average counts of all forms of ripening follicles (from the stage of primary follicles to tertiary follicles) was found in the Stein–Leventhal ovaries compared to the control ovaries by histological observations . As expected, the percentage of healthy women with isolated PCOM was greatly reduced (only 7%) by applying the revised threshold of antral follicles . Recently, Christ et al. With the advance of imaging technology, numerous efforts have been made to define the ovarian appearance in women with PCOS and the ultrasound criteria of PCOM have been refined over time. They start in the stroma or the sex cords. Elevated concentrations of the angiogenic factors including vascular endothelial growth factor, angiopoietins, and basic fibroblast growth factors were also observed in the serum and/or follicular fluid of women with PCOS during controlled ovarian hyperstimulation and may play an important role in the increased risk of ovarian hyperstimulation syndrome in PCOS . On ultrasound, fibromas most commonly manifest as solid, hypoechoic masses with ultrasound … However, a recent study recommended against the use of ovarian stromal measurements in the diagnosis of PCOS, as substantially lower diagnostic potential was found compared to FNPO and ovarian volume . The sensitivity for PCOS diagnosis was 21%, 4%, 62%, and 100%, respectively. The histopathological characteristics of Stein–Leventhal ovaries are as follows : Bilaterally enlarged ovaries (two to five times the normal size); Multiple small follicles typically of similar size (<1 cm in diameter) densely packed and lined within the superficial cortex; Increased stroma, occasionally with luteinized cells (hyperthecosis); Morphological signs of an absence of ovulation (thick smooth capsule and absence of corpora lutea and corpora albicans); Hyperplasia and luteinization of the inner theca cell layer. The shift of diagnosis from non-hyperandrogenic PCOS to hypothalamic anovulation challenged the inclusive Rotterdam definition of PCOS and manifested the inadequacy of diagnostic strategies. Ultrasound Obstet Gynecol. Author information: (1)Department of Obstetrics and Gynecology, Universitá Cattolica del Sacro Cuore, Rome, Italy. Polycystic ovary syndrome (PCOS) is a common endocrine disorder of unknown etiology, affecting 6–8% of reproductive-aged women . The 3D stromal volume was obtained by subtracting the total follicular volume from the total ovarian volume. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. SCSTs are rare. Comparison of the numeric variables between different studies would be possible until a standard machine setting for 3D Doppler measurement is adopted universally . Although the 3D technique allowed quantifying the echogenicity of the ovarian stoma by calculating the mean pixel intensity, its validity has not been proved. Diagnosis of the syndrome is generally based clinically on the presence of amenorrhoea/oligomenorrhoea or symptoms of hyperandrogenism, and biochemically on the presence of elevated serum luteinizing hormone (LH) and androgen concentrations. 1 A). A new ultrasound criterion for the diagnosis of polycystic ovary syndrome: the ovarian stroma/total area ratio. There is no single diagnostic test for this complex disorder. PCOS is defined as a clinical syndrome characterized by oligoamenorrhea, obesity, infertility, and signs of excess androgen. Clinical efficacy and metabolic impact of two different dosages of ethinyl-estradiol in association with drospirenone in normal-weight women with polycystic ovary syndrome: a randomized study. Design: 2020 Sep;160(3):R25-R39. The Distribution of Stroma and Antral Follicles Differs between Insulin-Resistance and Hyperandrogenism-Related Polycystic Ovarian Syndrome. Whether a larger follicle pool in PCOS patients observed in these findings is due to the prolonged survival of PCOS follicle remains unclear . Lee DE, Park SY, Lee SR, Jeong K, Chung HW. Sex cord stromal tumours (SCSTs) are rare tumours of the ovary. COVID-19 is an emerging, rapidly evolving situation. The ovaries — each about the size of an almond — produce eggs (ova) as well as the hormones estrogen and progesterone.Ovarian cancer often goes undetected until it has spread within the pelvis and abdomen. 4 A). Antral follicles measure 2–9 mm in average diameter and increased antral follicle number per ovary (FNPO) is a key and consistent morphological feature of polycystic ovary. Ovarian Torsion. The findings of the two sides showed no significant difference in the statistical scale. In an attempt to assess the follicle size distribution in PCOS ovaries, Jonard et al. NLM Report of 8 cases. described a scoring method to determine the distribution patterns by evaluating the largest cross-sectional plane (contains ≥9 follicles) of each ovary: 1 = clear follicle aggregation around the periphery with ≤1 central follicle, 2 = follicle aggregation around the periphery with >1 central follicle, and 3 = follicle scattered throughout the ovarian stroma . It was the first report to link ovarian pathology with clinical hyperandrogenism and oligoamenorrhea. Ovarian stromal hyperthecosis (SH) has variable clinical importance but can cause hyperan- drogenism, particularly in premenopausal women. Notably, the threshold of 10 cm 3 proposed by Rotterdam consensus was chosen empirically based on opinions of the expert panel. Lujuan et al. A: Note the enlarged Lt ovary in the absence of masses, its maximum dimension was 6.2 cm, as well as the free pelvic collection (yellow arrow), the tiny peripherally arranged follicles and the central afollicular stroma. Ultrasound diagnosis of polycystic ovary syndrome. Epub 2013 Nov 1. 4 B). Sonography is often used to evaluate the ovaries of women with hyperandrogenism, but there is little published regarding the sonographic appearance of B: Absent intra-ovarian vascularity by Color Doppler US. Fulghesu AM, Angioni S, Belosi C, Apa R, Selvaggi L, Ciampelli M, Iuculano A, Melis GB, Lanzone A. Clin Endocrinol (Oxf). 2013 Sep;36(8):636-41. doi: 10.1007/BF03346756. Diagnostic Usefulness of Transrectal Ultrasound Compared with Transvaginal Ultrasound Assessment in Young Korean Women with Polycystic Ovary Syndrome. 1996 Apr;10(2):249-62. doi: 10.1016/s0950-351x(96)80099-1. Out of 100 women with ovarian cancer, around 5 will have a SCST (around 5%). Carvalho RB, Cintra ML, Matos PS, Campos PS. However, the great variability in symptoms and clinical and biochemical manifestations of PCOS make the aetiology and pathophysiology unclear (Franks, 1994; Conway, 1996). Recently, the technique of spatiotemporal image correlation (STIC) and high-definition flow (HDF) were also introduced . The morphological features of the ovaries in women with polycystic ovary syndrome (PCOS) have been well described by ultrasound imaging technology. Meigs syndrome: consists of ovarian fibroma with ascites and a pleural effusion; fibromas are seen in 75% of patients with nevoid basal cell carcinoma syndrome 1; Radiographic features Ultrasound. Compared to FNPO, the threshold of 26 follicles had the best compromise between sensitivity (85%) and specificity (94%). The underlying mechanisms for excessive antral follicle formation remain unclear . Alfie Cohen I, Castillo Aguilar E, Sereno Gomez B, Martinez Rodriguez O.Struma ovarii: a variety of monodermic teratoma of the ovary. The 2D stromal area was evaluated by tracing with the caliper the peripheral profile of the stroma in the maximum plane section of the ovary ( Fig. The stroma and the sex cords are tissues that support the ovary and from which different cells develop. Diagnostic criteria for PCOS: Is there a need for a rethink?  |  Subtle changes in the power Doppler settings including gain, power, pulse repetition frequency, wall motion filter, signal rise and persistence, and speed of acquisition were found to significantly increase or decrease the final results of 3D vascular indices . Transabdominal US images from a 9 yr old girl with torsed Lt ovary. Although the 3D (three-dimensional) method of measuring the ovarian volume avoids the use of geometric assumption, it is not recommended due to the technical and interobserver variability . The 2 tests used most often (in addition to a complete pelvic exam) to screen for ovarian cancer are transvaginal ultrasound (TVUS) and the CA-125 blood test. A number of studies have shown that the vascularization index (VI), flow index (FI), and vascularization flow index (VFI) were significantly higher in the women with PCOS compared with the women with normal ovaries . The model also showed that 69% of the variation in ovarian volume is due to age alone. Please enable it to take advantage of the complete set of features! Ultrasound is non-invasive and a widely used modality for evaluating such cases. J Clin Endocrinol Metab. The entire ovarian stroma is … In addition, the changes in ovarian volume with age need to be considered when defining PCOM. These data confirm the presence of an initial excessive early follicular growth and suggest that the abnormalities of folliculogenesis occur at early stages of follicle development. Objectives Cystadenofibromas (CAFs) are rare benign ovarian tumors without a widely accepted ultrasound (US) pattern. Ovarian cancer is a type of cancer that begins in the ovaries. ?12-mm peripheral follicles is a common ultrasound finding that can be found in up to 74% of cases [2, 10]. If there is reason to suspect you have ovarian cancer based on your symptoms and/or physical exam, your doctor will order some tests to check further. However, no standardized method to assess this morphological feature exists. In the GCP, “microcysts” occupied the entire parenchyma of the ovary ( Fig. The female reproductive system contains two ovaries, one on each side of the uterus. It is similar to the results obtained by Dewailly et al. The S/A ratio was positively correlated with the testosterone and androstenedione levels . To confirm stromal ovarian hyperplasia, doctors conduct differential diagnosis with fibroma, cancer processes or stromal endometrial sarcoma. In the PCP, “microcysts” were aligned in the subcapsular region of the ovary ( Fig. It is hypothesized that high vascularization may lead to an abnormal growth of the theca interna (which is the site for androgen steroidogenesis) with subsequent hyperandrogenemia . Kinnear HM, Tomaszewski CE, Chang FL, Moravek MB, Xu M, Padmanabhan V, Shikanov A. Reproduction. The subsequent follicular arrest is the failure of follicle development to proceed beyond the mid-antral stage, giving the characteristic appearance of multifollicular ovaries on ultrasound . Magnetic resonance imaging has the potential to be an alternative imaging modality for diagnosing PCOM in adolescence. Increased ovarian stromal blood velocity may be a new parameter to assist in the ultrasound diagnosis of PCO. In 2014, the Androgen Excess Society and Polycystic Ovary Syndrome Society (AEPS) guidelines recommended using FNPO (follicle number per ovary) ≥25 for the definition of PCOM when using the newer technology that affords maximal resolution of ovarian follicles (i.e., transducer frequency >8 MHz). This is usually assessed subjectively. The S/A ratio showed the most significant correlation with the androgen levels. In PCOS, the ovarian stroma becomes enlarged enclosing an increased number of small follicles that encircle the outer layer of the ovarian stroma and looks a lot like a string of pearls on an ultrasound. Increased stromal echogenicity is a characteristic feature of the polycystic ovaries. Ovarian morphology as a predictor of hormonal values in polycystic ovary syndrome. 1997 Mar;67(3):452-8. doi: 10.1016/s0015-0282(97)80068-4. The features of a typical polycystic ovary appearance that can be identified by ultrasound show a high concordance with these histopathological characteristics : enlarged ovaries that are usually more spherical in shape; multiple small follicles of similar size arranged around the periphery, giving the appearance of a “string-of-pearls”; the increased and hyperechoic stroma occupying the center of the ovaries; and. Polycystic ovaries (PCO) have been reported to occur in about 20% of the general female population (Polson et al., 1988) and in up to 50% of women presenting to infertility clinics (Jacobs, 1987). Assisted conception units have long been aware of the value of ultrasound. Clipboard, Search History, and several other advanced features are temporarily unavailable. Given that the ovarian volume threshold values might depend on the clinical and metabolic characteristics of the population studied, the AEPS guidelines highly recommended the use of in-house reference normal values. 2017 May 31;8:117. doi: 10.3389/fendo.2017.00117. evaluation of ovarian torsion. The diagnostic criteria for polycystic ovarian morphology are described. Clinical review: Lifecycle of polycystic ovary syndrome (PCOS): from in utero to menopause. Among these features, follicle number and ovarian volume are the sonographic parameters chosen to establish the diagnostic criteria for polycystic ovary. This highlights the importance of strict maintenance of the machine settings if any two subjects are to be compared. The term hyperthecosis refers to the presence of nests of luteinized theca cells in the ovarian stroma due to differentiation of the ovarian interstitial cells into steroidogenically active luteinized stromal cells ().These nests or islands of luteinized theca cells are scattered throughout the stroma of the ovary, rather than being confined to areas around cystic … doi: 10.1016/j.fertnstert.2013.10.001. 2013 Dec;98(12):4629-38. doi: 10.1210/jc.2013-2375. (ABSTRACT TRUNCATED AT 250 WORDS) PMID: 8567828 [Indexed for MEDLINE] The ovarian stroma and uterine artery of all patients were examined by 2D color Doppler and wave spectra were consequently recorded. In a study of normogonadotropic anovulatory infertile women, an increase of antral follicle threshold from 12 to 25 lowers the prevalence of PCOS from 93.3% to 54.7%.
