Answer:
Gonadotrophin
Explanation:
*GONADOTROPHINS:These are *hormones produced by the anterior lobe of the pituitary gland that regulate the male and female reproductive organ*. The two Gonadotrophins are *Follicle stimulating hormone(FSH) and Luteinising hormone(LH)*. Both are glycoproteins.
*Follicle stimulating hormone stimulates spermatogenesis by stimulating the sertoli cells to complete the development of spermatozoa from spermatids*.
*Luteinising hormone stimulates the synthesis of the hormone "testosterone" by the leydig (interstitial cells) of the testis*. Testosterone is a steroid hormone and is made from cholesterol, It stimulates growth and development of the germinal epithelial cells (spermatogonia) to form sperms,and also works with follicle stimulating hormone to stimulate sertoli cells.
