Polycystic ovarian syndrome (PCOS) is one of the most common endocrine disorders. The aim of this study was to find the correlation between color Doppler ultrasound and serum tests as auxiliary diagnostic criteria in areas where there is no possibility of some tests. A total of 108 patients were enrolled. They were divided into three groups including patients with PCOS, patients with PCOA ultrasound, patients with ovaries and normal hormone tests. Transvaginal sonography was performed from three groups and the results were evaluated in gray scale. The volume of the ovary, the number of follicles and the placement of follicles were recorded using using Doppler spectrum of uterine artery and ovarian stroma. Their arterial resistance index was also calculated. In the next step, serum samples were evaluated to determine the level of LH, FSH, free testosterone, DHEAS and 17-OHP hormones in the early follicular phase. Gray scale ultrasonographic findings (volume and number of ovarian follicles) as well as LH values were higher in patients with PCOS than those in the other two groups. These results proved the reliability of using these factors in the prediction of PCOS. In this study, Doppler indexes did not correlate with the size of the ovaries, the number of ovarian follicles and the measured hormone levels. The findings of transvaginal ultrasound and investigating the relationship with clinical and laboratory outcomes, a more suitable pattern could be chosen for more accurate patient selection and, leading to timely treatment and reducing the complications of the disease.

Classic galactosemia is a rare inborn error of galactose metabolism with a birth prevalence of about 1/30,000–60,000. Long-term complications occurring despite dietary treatment consist of premature ovarian insufficiency (POI) and neurodevelopmental impairments. We performed with the French Reference Centers for Rare Diseases a multisite collaborative questionnaire survey for classic galactosemic patients. Its primary objective was to assess their puberty, pregnancy, gonadotropic axis, and pelvic morphology by ultrasound. The secondary objective was to determine predictive factors for pregnancy without oocyte donation. Completed questionnaires from 103 patients, 56 females (median age, 19 years (3–52 years)) and 47 males (median age, 19 years (3–45 years)), were analyzed. Among the 43 females older than 13 years old, mean age for breast development first stage was 13.8 years; spontaneous menarche occurred in 21/31 females at a mean age of 14.6 years. In these 21 women, 62% had spaniomenorrhea and 7/17 older than 30 years had amenorrhea. All age-groups confounded, FSH was above reference range for 65.7% of the patients, anti-Müllerian hormone and inhibin B were undetectable, and the ovaries were small with few or no follicles detected. Among the 5 females who sought to conceive, 4 had pregnancies. Among the 47 males, 1 had cryptorchidism, all have normal testicular function and none had a desire to conceive children. Thus, spontaneous puberty and POI are both common in this population. Spontaneous menarche seems to be the best predictive factor for successful spontaneous pregnancy.

Concern has been raised over chemical-induced disruption of ovary development during fetal life resulting in long-lasting consequences only manifesting themselves much later during adulthood. A growing body of evidence suggests that prenatal exposure to the mild analgesic acetaminophen/paracetamol can cause such a scenario. Therefore, in this review, we discuss three recent reports that collectively indicate that prenatal exposure in a period of 13.5 days post coitum in both rats and mouse can result in reduced female reproductive health. The combined data show that the exposure results in the reduction of primordial follicles, irregular menstrual cycle, premature absence of corpus luteum, as well as reduced fertility, resembling premature ovarian insufficiency syndrome in humans that is linked to premature menopause. This could especially affect the Western parts of the world, where the age for childbirth is continuously being increased and acetaminophen is recommended during pregnancy for pain and fever. We therefore highlight an urgent need for more studies to verify these data including both experimental and epidemiological approaches.

Intrauterine life may be implicated in the origin of polycystic ovary syndrome (PCOS) modifying the endocrine and metabolic functions of children born to PCOS mothers independently of the genetic inheritance and gender. The aim of the present study was to evaluate the reproductive and metabolic functions in sons of women with PCOS during puberty.
Sixty-nine PCOS sons (PCOSs) and 84 control sons of 7–18 years old matched by the Tanner stage score were studied. A complete physical examination was conducted including anthropometric measurements (weight, height, waist, hip and body mass index). An oral glucose tolerance test was performed and circulating concentrations of luteinizing hormone, follicle-stimulating hormone (FSH), sex hormone-binding globulin, testosterone, androstenedione (A4), 17α-hydroxyprogesterone (17-OHP) and AMH were determined in the fasting sample.
Waist-to-hip ratio, FSH and androstenedione levels were significantly higher in the PCOSs group compared to control boys during the Tanner stage II–III. In Tanner stages II–III and IV–V, PCOSs showed significantly higher total cholesterol and LDL levels. Propensity score analysis showed that higher LDL levels were attributable to the PCOSs condition and not to other metabolic factors. AMH levels were comparable during all stages. The rest of the parameters were comparable between both groups.
Sons of women with PCOS show increased total cholesterol and LDL levels during puberty, which may represent latent insulin resistance. Thus, this is a group that should be followed and studied looking for further features of insulin resistance and cardiovascular risk markers. Reproductive markers, on the other hand, are very similar to controls.

Ultra-sensitive hormone assays have detected slight sex differences in blood estradiol (E2) levels in young children before adrenarche. However, the origin of circulating E2 in these individuals remains unknown. This study aimed to clarify how E2 is produced in young girls before adrenarche.
This is a satellite project of the Japan Environment and Children’s Study organized by the National Institute for Environmental Studies.
We collected blood samples from healthy 6-year-old Japanese children (79 boys and 71 girls). Hormone measurements and data analysis were performed in the National Institute for Environmental Studies and the Medical Support Center of the Japan Environment and Children’s Study, respectively.
E2 and follicle stimulating hormone (FSH) levels were significantly higher in girls than in boys, while dehydroepiandrosterone sulfate (DHEA-S) and testosterone levels were comparable between the two groups. Girls showed significantly higher E2/testosterone ratios than boys. In children of both sexes, a correlation was observed between E2 and testosterone levels and between testosterone and DHEA-S levels. Moreover, E2 levels were correlated with FSH levels only in girls.
The results indicate that in 6-year-old girls, circulating E2 is produced primarily in the ovary from adrenal steroids through FSH-induced aromatase upregulation. This study provides evidence that female-dominant E2 production starts several months or years before adrenarche. The biological significance of E2 biosynthesis in these young children needs to be clarified in future studies.

Oxidative stress seems to be present in patients with polycystic ovary syndrome (PCOS). The aim of this study was to evaluate the correlation between characteristics of PCOS and serum concentrations of afamin, a novel binding protein for the antioxidant vitamin E. A total of 85 patients with PCOS and 76 control subjects were investigated in a pilot cross-sectional study design between 2009 and 2013 in the University Hospital of Essen, Germany. Patients with PCOS were diagnosed according to the Rotterdam ESHRE/ASRM-sponsored PCOS Consensus Workshop Group. Afamin and diagnostic parameters of PCOS were determined at early follicular phase. Afamin concentrations were significantly higher in patients with PCOS than in controls (odds ratio (OR) for a 10 mg/ml increase in afamin=1.3, 95% CI=1.08–1.58). This difference vanished in a model adjusting for age, BMI, free testosterone index (FTI), and sex hormone-binding globulin (SHBG) (OR=1.05, 95% CI=0.80–1.38). In patients with PCOS, afamin correlated significantly with homeostatic model assessment-insulin resistance (HOMA-IR), fasting glucose, BMI, FTI, and SHBG (P<0.001), but in a multivariate linear model, only HOMA-IR remained significantly associated with afamin (P=0.001). No correlation was observed between afamin and androgens, LH, FSH, LH/FSH ratio, antral follicle count, ovarian volume, or anti-Müllerian hormone. In conclusion, elevated afamin values may indicate a state of oxidative stress and inflammation, strongly associated with IR and offering an indicator of impaired glucose tolerance in patients with PCOS irrespective of obesity.

Long-term maintenance of functional activity of thyroid cells is an essential requirement for basic in vitro studies on the physiology and pathology of the thyroid. An important prerequisite of thyrocytes’ functional activity in vivo and in vitro is their follicle organization.
This study aimed at developing a method of cultivation of functionally active rat thyroid follicles in Matrigel under three-dimensional conditions.
Undamaged rat thyroid follicles were isolated by enzymatic digestion with collagenase/dispase, then embedded into Matrigel, and cultivated for 2 weeks. Thyroglobulin, thyroxine and zonula occludens-1 (ZO-1) localization were revealed by immunofluorescence analysis. Iodide organification was tested by protein-bound 125I (PBI) measurement.
Integrity of the follicles was preserved during the whole period of cultivation and was confirmed by 3D reconstruction of ZO-1 localization. Thyroglobulin was detected in the thyrocyte cytoplasm, as well as in the intrafollicular lumen. Thyroxine was observed predominantly at the apical side of thyrocytes. Also, generated cultures were characterized by a high level of iodide organification: PB125I represented 39% of the total radioactivity in the Matrigel drop embedding the follicles; at the same time, methimazole almost totally inhibited this process (0.2% of total radioactivity).
The method of rat thyrocyte cultivation in Matrigel, as described here allows to maintain the structural integrity and the functional activity of thyroid follicles in vitro and could be used for wide ranges of basic and applied researches in thyroidology.

It is recognised that ovarian factors, including steroid and protein hormones, are critical in the feedback regulation of pituitary gonadotropins; however, their individual contributions are less defined. The aim of this study was to explore the reciprocal relationships between ovarian and pituitary hormones across the normal ovulatory menstrual cycle as women age. FSH, LH, oestradiol, progesterone, inhibin A, inhibin B and anti-mullerian hormone (AMH) were measured in serum collected every 1–3 days across one interovulatory interval (IOI) from 26 healthy women aged 18–50 years. The antral follicle count (AFC) for follicles 2–5 mm, >6 mm and 2–10 mm were tabulated across the IOI. Independent associations between ovarian hormones/AFC vs pituitary follicle-stimulating hormone (FSH) and luteinising hormone (LH) were investigated using multivariate regression analysis. The data were sub-grouped based on the presence or absence luteal phase-dominant follicles (LPDF). Serum oestradiol and AMH were inversely correlated with FSH in both follicular and luteal phases. Inhibin B correlated inversely with FSH and LH in the late follicular phase and directly in the luteal phase. AFC, inhibin A and progesterone were not key predictors of either FSH or LH. The strong association between AMH and FSH with age implies that AMH, as well as oestradiol and inhibin B are important regulators of FSH. The change in feedback response of inhibin B with both FSH and LH across the cycle suggests two phases of the negative feedback.

Objective: To investigate markers of premature menopause (<40 years), and specifically the prevalence of autoimmune primary ovarian insufficiency (POI) in European women.
Design: Postmenopausal women were categorized according to age at menopause and self-reported reason for menopause in a cross-sectional analysis of 6870 women.
Methods: Variables associated with timing of menopause and hormone measurements of 17β-estradiol and follicle stimulating hormone (FSH) were explored using multivariable logistic regression analysis. Specific immunoprecipitating assays of steroidogenic autoantibodies against 21-hydroxylase (21-OH), side chain cleavage enzyme (anti-SCC) and 17alpha-hydroxylase (17 OH) as well as NACHT leucine-rich-repeat protein 5 (NALP5) were used to identify women with likely autoimmune POI.
Results: Premature menopause was identified in 2.8% of women, and these women had higher frequencies of nulliparity (37.4% vs 19.7%), obesity (28.7% vs 21.4%), osteoporosis (17.1% vs 11.6%), hormone replacement therapy (59.1% vs 36.9%) and never smokers (60.1% vs 50.9%), (p<0.05), compared to women with menopause ≥ 40 years. Iatrogenic causes were found in 91 (47%) and non-ovarian causes in 27 (14%) women, while 77 (39%) women were classified as POI of unknown cause, resulting in a 1.1% prevalence of idiopathic POI. After adjustments nulliparity was the only variable significantly associated with POI (OR 2.46; 95% CI 1.63-3.42). Based on the presence of autoantibodies against 21 OH and SCC, 4.5% of POI cases were of likely autoimmune origin.
Conclusion: Idiopathic POI affects 1.1% of all women and almost half of women with premature menopause. Autoimmunity explains 4.5% of these cases judged by positive steroidogenic autoantibodies.

The knowledge about health status in adults with disorder of sex development (DSD) is scarce.
Design and methods
A cross-sectional observational study in 14 European tertiary centers recruited 1040 participants (717 females, 311 males, 12 others) with DSD. Mean age was 32.4 ± 13.6 year (range 16–75). The cohort was divided into: Turner (n = 301), Klinefelter (n = 224), XY-DSD (n = 222), XX-DSD (excluding congenital adrenal hyperplasia (CAH) and 46,XX males) (n = 21), 46,XX-CAH (n = 226) and 45,X/46,XY (n = 45). Perceived and objective health statuses were measured and compared to European control data.
In DSD, fair to very good general health was reported by 91.4% and only 8.6% reported (very) bad general health (controls 94.0% and 6.0%, P < 0.0001). Longstanding health issues other than DSD and feeling limited in daily life were reported in 51.0% and 38.6%, respectively (controls 24.5% and 13.8%, P < 0.0001 both). Any disorder except DSD was present in 84.3% (controls 24.6%, P < 0.0001). Males reported worse health than females. In the subgroup analysis, Klinefelter and 46,XX-DSD patients reported bad general health in 15.7% and 16.7%, respectively (Turner 3.2% and CAH 7.4%). Comorbidities were prevalent in all DSD subgroups but Klinefelter and Turner were most affected. Early diagnosis of DSD and a healthy lifestyle were associated with less comorbidities.
Overall, general health appeared to be good but a number of medical problems were reported, especially in Klinefelter and Turner. Early diagnosis of DSD and a healthy lifestyle seemed to be important. Lifelong follow-up at specialized centers is necessary.
