چکیده

Background: Inhibin selectively inhibits FSH but not LH secretion. Data are somewhat conflicting regarding differences in inhibin between normally cycling women and those with polycystic ovarian syndrome (PCOS). The Aim of this Study: Is to study the pattern of inhibinB hormone secretion in cases of PCOS throughout days 3, 5 and 9 of their menstrual cycles. Patients and Methods: The study was performed on 29 women with PCOS, 5ml of blood were collected at days 3, 5 and 9 of the menstrual cycle of each participant for Measurement of inhibin-B hormone. Results: Inhibin B hormone showed an increase in concentration along the studied days of menstrual cycle. There was a highly significant negative correlation between day 3 as well as day 5 inhibin B concentrations and body mass index (BMI), while day 9 inhibin B concentrations showed a non significant correlation with BMI. Day 3, 5 and 9 inhibin B concentrations showed a non significant correlation with age as shown in Table (3). Conclusion: Inhibin B can’t be used alone to diagnose a case of PCOS due to absence of a characteristic pattern of secretion.

The effect of exosomes derived from human ovarian epithelial cancer cells on the secretion of AMH and Inhibin in granulosa cells

Exosomes are secreted by different types of cells and known as biological packages. Exosomes have significant role in intercellular communications and involved in the development and progression of various diseases such as cancer. Inhibin B and anti-mullerian hormone (AMH) are markers of granulosa cell tumors (GCT) and due to the role of exosomes in the progression of cancer, in this experiment...

Comparison of follicle-stimulating-hormone-stimulated dimeric inhibin and estradiol responses as indicators of granulosa cell function in polycystic ovary syndrome and normal women.

CONTEXT Follicular phase secretion of inhibin B, like that of estradiol (E(2)), correlates with the quantity and quality of developing follicles. However, it has not been established whether inhibin B responses to gonadotropin stimulation parallel those of E(2) as a reflection of granulosa cell functional capacity. OBJECTIVE Our objective was to determine whether inhibin B responses to FSH st...

Serum anti-Müllerian hormone levels remain high until late reproductive age and decrease during metformin therapy in women with polycystic ovary syndrome.

BACKGROUND Anti-Müllerian hormone (AMH) is secreted by granulosa cells of ovarian early developing follicles and its serum levels have been shown to correlate with small antral follicle number. Since the pronounced androgen secretion from follicles/stroma in women with polycystic ovary syndrome (PCOS) remains until late reproductive age, and since AMH reflects the number of antral follicles, it...

Changes in serum immunoreactive inhibin during ovulation induction in women with amenorrhea.

Changes in serum immunoreactive (IR)-inhibin were measured by RIA in two studies, in order to elucidate, firstly whether the pattern of IR-inhibin secretion is similar to that of estradiol (E2), and secondly, whether inhibin suppresses endogenous FSH release. Study 1: Purified urinary FSH (pFSH) or human menopausal gonadotropin (hMG) were daily injected intramuscularly into women with hypogonad...

OBJECTIVE To evaluate the performance of antimullerian hormone (AMH) and inhibin B as ovarian function markers for differentiating common causes of secondary oligoamenorrhea, namely hypogonadotrophic hypogonadism (HH), polycystic ovary syndrome (PCOS), premature ovarian failure (POF), and hyperprolactinemia (HPRL). DESIGN Retrospective analysis. SETTING Two university hospitals. PATIENT(S...
