OBJECTIVE: Testicular dysgenesis syndrome (TDS) comprises testicular germ cell cancer, cryptorchidism and some cases of male infertility and hypospadias, which can be linked to impairment of intrauterine gonadal development. Among histological signs of TDS, large Leydig cell (LC) clusters (micronodules) are frequently present. This study aimed to investigate possible associations of LC micronodules with the presence of Reinke crystals and hormonal function of LCs, the latter primarily reflected by serum concentrations of luteinising hormone (LH) and testosterone, in patients with TDS...

The low take-home baby rate in older women in Australia (5.8%) undergoing IVF is linked to the depletion of the ovarian reserve of primordial follicles. Oocyte depletion causes an irreversible change to ovarian function. We found that the young patient FSH receptor and LH receptor expression profile on the granulosa cells collected from different size follicles were similar to the expression profile reported in natural cycles in women and sheep. This was reversed in the older patients with poor ovarian reserve...

Previous studies have shown that serum zinc and adiponectin levels are associated with insulin resistance in the polycystic ovary syndrome (PCOS) patients. But there is no study to evaluate serum zinc and adiponectin levels as predictor markers of PCOS, adjusted for anthropometric, biochemical, dietary intake, and physical activity measures. Ninety-one new PCOS cases (based on the Rotterdam criteria) and 85 healthy control women participated and individually matched based on age. Food intake of all participants obtained by the food frequency and physical activity level was assessed by the International Physical Activity Questionnaires...

There are variant rates of oocyte degeneration after intracytoplasmic sperm injection (ICSI) among different patients. Oocyte degeneration after ICSI may reflect the cohort of oocyte quality and subsequent embryo development capacity and clinical outcome. This retrospective study analyzed 255 cycles with at least one degenerated oocyte after ICSI (degeneration group) and 243 cycles with no degenerated oocytes after ICSI (control group). Basic characteristics like female age, body mass index, duration of infertility, hormone (FSH, LH, E2) levels on day 3 of menses, and primary infertility patient rate were similar between the two groups (p > 0...

OBJECTIVE: Recent studies of perimenopausal women have observed associations of follicle-stimulating hormone (FSH) levels with markers of insulin resistance, independent of estradiol. Whether FSH is related to type 2 diabetes (T2D) in older women who have completed the menopause transition remains unknown. We assessed the association of FSH levels with diabetes and measures of insulin resistance among 588 postmenopausal Finnish women. METHODS: Study participants were aged 53 to 73 years and not using hormone therapy at baseline (1998-2001) when FSH was measured...

We investigated arsenite exposure on the reproductive axis of dams (during pregnancy and at cyclicity resumption) and their offspring. Pregnant rats were exposed to 5 (A5) or 50ppm (A50) of sodium arsenite in drinking water from gestational day 1 (GD1) until sacrifice at GD18 or two months postpartum. Offspring were exposed to the same treatment as their mothers from weaning to adulthood. A50-pregnant rats gained less weight, showed increased testosterone and estradiol but pregnancy was unaffected. After lactation, arsenic-exposed dams presented compromised cyclicity, decreased estradiol, increased follicle-stimulating hormone (FSH), less preovulatory follicles and presence of ovarian cysts, suggesting impaired reproduction...

Background: Low testosterone levels are a common finding among men with Type 2 Diabetes Mellitus (T2DM) and are inversely related to insulin resistance. Whether this relationship holds true in patients with hypertension, but normal glucose tolerance or prediabetes, is unclear. Methods: We recruited 87 male outpatients with essential arterial hypertension, aged 35-70 years. Anthropometric data were collected, an Oral Glucose Tolerance Test (OGTT) performed, and the homeostasis model assessment of insulin resistance (HOMA-IR) score calculated...
