Spermatogenesis is under the regulatory influence of
ADH
FSH
LH
STH

FSH
Follicle Stimulating Hormone (FSH) is produced by basophilic cells of adenohypophysis of the pituitary gland. In females, this hormone is responsible for the growth of ovarian follicles up to ovulation, while in males, its functions are the development of seminiferous tubules and maintenance of spermatogenesis.

Gamete Intra Fallopian Transfer
Gamete Intra Fallopian Transfer (GIFT) is an Assisted Reproductive Technology (ART). In this technique, eggs are removed from the woman and placed in one of the Fallopian tubes, along with the man's sperm. This allows fertilisation to take place inside the woman's body. Therefore, this variation is actually an in vivo fertilisation, not an in vitro fertilisation.

Saheli is the world's first non-steroidal, oral pills. It can be only taken once a week. It contains centchroman and its functioning is based upon selective Estrogen Receptor modulation.
The function of copper ions in copper releasing IUD's is :
They suppress sperm motility and fertilising capacity of sperms
They inhibit gametogenesis
They make uterus unsuitable for implantation
