Introduction. Male infertility, caused by a high level of sperm DNA fragmentation, remains one the significant problems reproductive medicine. One methods to overcome it may be use recombinant follicle-stimulating hormone (FSH), but results studies on this issue are ambiguous. The purpose literature review is systematize publications issue. Materials and methods. search, analysis systematizatio...

background: polycystic ovary syndrome (pcos) is a disorder in which there are numerous benign cysts that form on ovaries under a thick white covering that is one of the causes of infertility. follistatin is a single chain glycosylated polypeptide that can bind to activin. when follistatin binds to activin it suppresses the role of activin to stimulate the secretion of follicle stimulating hormo...

A highly purified follicle-stimulating hormone from human pituitary glands has been prepared by ammonium sulfate and ethanol fractionation, gel filtration on Sephadex G-100, ion exchange chromatography on carboxymethyl cellulose, zone electrophoresis on cellulose columns, and preparative continuous flow polyacrylamide gel electrophoresis. The final product has shown lO,OOO-fold purification ove...

Background: Infertility is defined as the inability to conceive after one two years of unprotected intercourse. It types: primary infertility and secondary 5On basis etiopathology divided into five groups: unexplained (28%), male factor (24%), ovarian dysfunction (21%), tubal (14%) others (13%). Luteinizing hormone (LH) follicle-stimulating (FSH) are integral parts neural endocrine interchange ...

Antibodies directed against human follicle-stimulating hormone (FSH) were demonstrated in rabbit serum by neutralization of biological activity. Antibodies that bound FSH-(131)I were produced in rabbits and guinea pigs by repeated injections of FSH. By (131)I immunochemical methods, we found that at least 90% of the FSH-(131)I-binding antibody failed to distinguish the four human glycoprotein h...

Ovarian follicle selection is an important process impacting the laying performance and fecundity of hens, and is regulated by follicle-stimulating hormone (FSH) through binding to its receptor [follicle-stimulating hormone receptor (FSHR)]. In laying hens, the small yellow follicle (6-8 mm in diameter) with the highest expression of FSHR will be recruited into the preovulatory hierarchy during...

To investigate the effect of thyroid hormone on the proliferative activity and apoptosis of granulosa cells at the varying stages of follicular growth, porcine granulosa cells obtained from small (1-2 mm), medium (3-5 mm) and large (6-11 mm) follicles were cultured under a serum-free condition in the presence or absence of follicle stimulating hormone (FSH; 20 ng/ml), with or without triiodothy...
