BACKGROUND Follicle-stimulating hormone (FSH), a member of gonadotropin family, is critical for follicular maturation and ovarian steroidogenesis. Serum FSH levels are known to fluctuate during different phases of menstrual cycle in premenopausal women, and increase considerably after the menopause as a result of ovarian function cessation. There is little existing evidence to guide researchers...

The Sertoli cell is the primary target for FSH action in the mammalian testis. These cells contain the majority of testicular plasma membrane receptors for this hormone. Receptor occupancy is directly correlated with a stimulation of adenylyl cyclase and a decrease in the activity of a cytoplasmic Ca++-sensitive cAMP phosphodiesterase. Regulation of these two enzymes allows increased intracellu...

Anticancer treatment can disturb gonadal function and deplete the primordial follicle pool, leading to premature menopause. We made a prospective analysis of serum hormone levels in young female cancer survivors who had been treated during childhood and adolescence. Serum anti-Müllerian hormone (AMH) as a marker of ovarian reserve, FSH, LH, and estradiol were measured in 33 women treated previo...

We evaluated ovarian function by measuring the levels of anti-Müllerian hormone (AMH), estradiol, and gonadotropins in 83 young women treated for cancer during childhood and adolescence, and classified according to post-treatment gonadal toxicity versus 38 healthy females. Results. The mean AMH values were lower in the entire cohort independently of the risk group as compared to the control, wh...

Kisspeptins have emerged as potent elicitors of gonadotropin secretion and, therefore, putative targets for pharmacological intervention. In this context, desensitization of gonadotropin responses to continuous administration of kisspeptins has begun to be characterized, but information so far available is mostly restricted to LH responses in males, whereas the similar phenomenon in females, of...

BACKGROUND Protocols of controlled ovarian hyper-stimulation (COH) require, as a crucial step, the identification of reliable predictors of ovarian reserve. Anti-Mullerian hormone (AMH) is one of the most reliable predictors of ovarian reserve but other factors including autoimmune thyroid diseases (ATD) have been associated with reduced fertility and poor COH outcome. Aim of the present study ...

Background: The objective of this study is to establish importance of anti-FSH antibodies in IVF outcome. Materials and Methods: This research was designed based on evaluation of several articles from 2000 till 2012 about anti-FSH antibodies in IVF outcome. Results: Serum concentrations of anti-FSH IgG and IgA were linearly associated with poorer ovarian stimulation outcome. For example 1.0 AU ...

The risk and severity of ovarian carcinoma, the leading cause of gynecologic malignancy death, are significantly elevated in postmenopausal women. Ovarian failure at menopause, associated with a reduction in estrogen secretion, results in an increase of the gonadotropic luteinizing hormone (LH) and follicle-stimulating hormone (FSH), suggesting a role for these hormones in facilitating the prog...

The aim of the research was to evaluate effectiveness optimized treatment in correction hormonal disorders women with abnormal uterine bleeding (AUB) and chronic psycho-emotional stress.
 Materials methods. 100 reproductive age AUB stress were examined. I group included 50 patients who received complex treatment, II persons standard treatment. control 30 healthy without stress. approach pr...
