Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone. [1] FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland [ 2 ] and regulates the development, growth, pubertal maturation , and reproductive processes of the body.
Additionally, FSH is involved in the male reproductive system by stimulating spermatogenesis (maturation of sperm cells) and initiating puberty. Studies show that variations in the FSHB gene can contribute to the likelihood of a woman becoming pregnant with fraternal, or dizygotic, twins. [ 8 ]
The endocrine function of gonadotrophs is derived from the effect of gonadotropins on the reproductive system. The gonadotropins produced by gonadotropic cells are FSH and LH, which are dimeric pituitary glycoprotein hormones with a common alpha subunit and distinct beta subunit that confers biological activity of the hormones.
These hormones are central to the complex endocrine system that regulates normal growth, sexual development, and reproductive function. [4] LH and FSH are secreted by the anterior pituitary gland, while hCG and eCG are secreted by the placenta in pregnant women and mares, respectively. [5]
FSH, luteinizing hormone. thyroid-stimulating hormone, and hCG are all known to affect Sertoli cell development and male reproductive health. FSH is required for Sertoli cell mitogen, which stimulates the expression of various cell markers. [7]
The reproductive system begins development at four to five weeks of gestation with germ cell migration. The bipotential gonad results from the collection of the medioventral region of the urogenital ridge. At the five-week point, the developing gonads break away from the adrenal primordium. Gonadal differentiation begins 42 days following ...
The male reproductive system is a series of organs located outside the body and around the pelvis region of a male that contribute towards the reproduction process. The primary direct function of the male reproductive system is to provide the male sperm for fertilization of the ovum. [3] The major reproductive organs of the male can be grouped ...
The main cause of infertility is due to obstructive azoospermia (OA). OA is a condition where there is a blockage in a male's reproductive tract, resulting in a lack of sperm in a male's ejaculate. This is mostly due to an absence of the vas deferens, which is thought to be caused by CFTR mutations.
