Although follicle stimulating hormone is often associated with the female reproductive cycle, it is actually essential to growth, physical development, pubertal processes, and reproduction in males. Specifically, it stimulates the maturation of sperm cells prior to them becoming functional.estosterone levels control the secretion of GnRH. When T levels are low, the hypothalamus releases more GnRH, which increases FSH as well as luteinizing hormone (LH) secretion. This increase in FSH in turn increases T levels in a self-correcting feedback loop.
