Gonadotropin-releasing hormone (GnRH) and activin regulate synthesis of FSH and ultimately fertility. Recent in vivo studies cast SMAD4 and FOXL2 as master transcriptional mediators of activin signaling that act together and independently of GnRH to regulate Fshb gene expression and female fertility. Ovarian hormones regulate GnRH and its receptor (GNRHR) through negative and positive feedback ...

Introduction: The role of ovarian hormones and nitric oxide (NO) in learning and memory and their interaction has been widely investigated. The present study carried out to evaluate different effect of L-NAME on spatial learning and memory of ovariectomized (OVX) and sham operated rats. Methods: 32 rats were divided into 4 groups: 1) Sham 2) OVX 3) Sham-LN and 4) OVX-LN. The animals of groups 3...

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...

Behaviorally subordinate female common marmosets (Callithrix jacchus) undergo suppression of ovulation and chronic reductions in basal plasma cortisol concentrations. Indirect evidence suggests that hypophyseal chorionic gonadotropin (CG; the major pituitary luteinizing gonadotropin in marmosets) may elevate cortisol concentrations in female marmosets, and therefore that social suppression of C...

Infertility is a main manifestation of endometriosis, though the exact pathogenesis endometriosis-associated infertility remains unclear. Compromised ovarian functions may be one causes endometriosis related infertility. The function can classified into three basic elements, (1) production hormones, (2) maintenance follicular development until ovulation, and (3) reservoir dormant oocytes (ovari...

Ovarian hormones are associated with binge eating in women, however findings are limited by the lack of experimental control inherent in human studies. Animal research that manipulates ovarian hormone status and examines individual differences in extreme binge eating proneness is needed to model clinical phenotypes in humans and to confirm causal effects. The purpose of this study was to examin...
