Background: Bovine follicle stimulating hormone (bFSH) belongs to the family of glycoprotein hormones that are released from the pituitary gland or the placenta. This hormone is a heterodimer consisting of common α- and specific β-subunit. Bovine FSH is used for reproductive technology such as superovulation in farm animals and polycystic ovary syndrome treatment. Also this hormone is produced ...

By integrating morphometrical and endocrinological data, as well as biological effects of various molecules synthesized by the human follicle, we propose a dynamic view of the follicle growth within the human ovary. Folliculogenesis starts with entry of resting follicles into the growth phase, a process where the kit system plays a key role. Several months are required for a new growing follicl...

OBJECTIVE To evaluate the relationship between serum gonadotropin level and parameters related to insulin resistance in Korean women with polycystic ovary syndrome (PCOS). METHODS This retrospective study included 138 women aged 18 to 35 years who were newly diagnosed with PCOS according to the Rotterdam consensus. Participants were divided into three groups based on the serum luteinizing hor...

The effect of space flight in a National Aeronautics and Space Administration (NASA) shuttle was studied in pregnant rats. Rats were launched on day 9 of gestation and recovered on day 20 of gestation. On day 20 of gestation, rats were unilaterally hysterectomized and subsequently allowed to go to term and deliver vaginally. There was no effect of space flight on pituitary and ovary mass postpa...

In ovarian antral follicles cumulus cells (approximately 1,000/follicle) closely surround the oocyte, and mural granulosa cells (approximately 50,000/follicle) are distributed at the periphery. Previous work (Salustri, A., Yanagishita, M., and Hascall, V. C. (1990) Dev. Biol. 138, 26-32) showed that oocytes produce a factor(s) which stimulates hyaluronic acid (HA) synthesis by cumulus cells dur...

The concentrations of serum homovanillic acid (HVA), luteinizing liormone (LH), follicle-stimulating hormone (FSH) and testosterone (T) were examined in 20 male schizophrenic patients not taking neuroleptic drugs, 44 treated with neuroleptic drugs, and 15 male healthy control subjects. Kurskal-Wallis analysis of variance showed no significant difference among the three groups in serum HVA, FSH,...

Objective: This study investigated the changes in the anterior pituitary hormones of patients who were admitted to an emergency service and diagnosed with acute meningitis. Methods: A total of 21 patients who were admitted to an emergency service between 01 January and 31 October 2012, and diagnosed with meningitis, were included. Blood samples were collected from the patients within an initial...

The phosphoinositide-3-kinase/Akt (PI3K/AKT) signaling pathway is crucial for Sertoli cell development and completing spermatogenesis. Its main role to promote proliferation inhibit apoptosis. Many factors activate the PI3K/AKT pathway, like hormones, such as follicle stimulating hormone (FSH), androgen, estrogen, insulin name a few. of these have receptors inside or on surface cells (SCs). Thi...

To better understand possible effects of bisphenol A (BPA) exposure on ovarian reserve in women with polycystic ovary syndrome (PCOS), we measured creatinine adjusted urinary BPA (BPA_Cre) concentrations and used regression models to evaluate the association between urinary BPA level and antral follicle count (AFC), antimullerian hormone (AMH), day-3 follicle stimulating hormone levels (FSH) an...

Anti-müllerian hormone (AmH) or müllerian inhibiting substance (mIS), is a dimeric protein part of the transforming growth factor (TGF)-beta subfamily. It plays two important roles in follicle genesis. First, it delays entrance of primordial follicle into pool of follicles in growth and secondly, it decreases the sensitivity of ovarian follicle toward follicle-stimulating hormone (FSH). The ova...
