Endometrial tissue is under a strong influence of sex hormones. These hormones are considered as developmental factors of endometrial hyperplasia and endometrial cancer. We examined the influence of gonadotropins (follicle-stimulating and luteinizing hormone) and sex hormones (estradiol, progesterone) on oxidant/antioxidant parameters in blood and endometrial tissue of women with complex endometrial hyperplasia. In blood, superoxide dismutase activity was significantly higher in luteal phase and postmenopause compared to the follicular phase...

CONTEXT: Thyroperoxidase antibody (TPOAb) positivity is the main risk factor for thyroid dysfunction during pregnancy and is consistently associated with premature delivery. However, the underlying mechanism is currently unknown. We hypothesized that TPOAb positivity may interfere with gestational thyroid stimulation induced by the pregnancy hormone human chorionic gonadotropin (hCG). DESIGN, SETTING AND PARTICIPANTS: TSH, FT4, TPOAbs and/or hCG concentrations were measured in early and late pregnancy of 7587 pregnant women from two Dutch population-based prospective cohorts (N=5924 Generation R; N=1663 HAPPY)...

CONTEXT: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age. Hyperandrogenism is the central feature of PCOS. Studies on isolated ovarian theca-interstitial cells suggest that resveratrol, a natural polyphenol, reduces androgen production. OBJECTIVE: This study was designed to evaluate endocrine and metabolic effects of resveratrol on PCOS. DESIGN AND SETTING: This was a randomized (1:1) double-blind, placebo-controlled trial that evaluated the effects of resveratrol over a period of 3 months in an academic hospital...

The menarcheal age of Korean women has been rapidly decreasing for the last 50 years, and the average menarcheal age of women born in the 1990s is approaching 12.6 years. In addition, interest in early puberty has been increasing recently owing to the rapid increase in precocious puberty. Generally, out of concern for short stature and early menarche, idiopathic central precocious puberty in female adolescents is treated with gonadotropin-releasing hormone analogs. Studies to date have described the association between early menarche and psychosocial problems such as delinquency and risky sexual behavior, as well as physical health problems such as obesity, diabetes, cardiovascular diseases, and breast cancer throughout the lifespan of women...

Gonadotropins (LH, FSH, and hCG) act in concert in the regulation of female reproductive system. Exploiting this influence, they are part of the assisted reproductive technique protocols. In this review we analyze the effectiveness of the different available gonadotropin formulations and the consequent adverse events. Moreover, different protocols for poor-responders and polycystic ovary syndrome affected women are explored. All these clinical different approaches have specific molecular bases, covered in this review starting from evolution and population genetics, getting to in vitro studies of gonadotropins action...

OBJECTIVE: To determine the preferred regimen for women with adenomyosis undergoing in vitro fertilization (IVF), we compared the IVF outcomes of fresh embryo transfer (ET) cycles with or without gonadotropin-releasing hormone (GnRH) agonist pretreatment and of frozen-thawed embryo transfer (FET) cycles following GnRH agonist treatment. METHODS: This retrospective study included 241 IVF cycles of women with adenomyosis from January 2006 to January 2012. Fresh ET cycles without (147 cycles, group A) or with (105 cycles, group B) GnRH agonist pretreatment, and FET cycles following GnRH agonist treatment (43 cycles, group C) were compared...

The aim of this study was to investigate whether the automatic measurement of follicular volume by three-dimensional (3D) ultrasound can predict the number of mature oocytes retrieved. A prospective cohort study including 47 women undergoing in vitro fertilization was conducted in a private fertility center. Follicular growth was monitored both manually and automatically using 3D scanning with SonoAVC on the day of human chorionic gonadotropin (hCG) administration. Regression analysis showed that under a standard protocol for hCG administration, the count of mature oocytes is well predicted by a multivariate model including the counts of follicles in the volume classes 2...

BACKGROUND: Intrauterine insemination (IUI) is a commonly used procedure to increase the infertile couples' chance of pregnancy. Single or double insemination and different timing choices are modifications of this intervention. The aim of this study was to elucidate the effect of the IUI procedure on clinical pregnancy rates when performed at 24 hours or 36 hours after ovulation triggered by human chorionic gonadotropin (hCG) following ovulation induction with gonadotropins. METHODS: One hundred and thirteen women diagnosed with polycystic ovarian syndrome (PCOS) (as per Rotterdam's criteria) or unexplained infertility, who were treated using gonadotropins for ovulation induction and IUI for increasing fertilization potential, were recruited from the medical records of the infertility clinic...
