In the male, the principal sex hormones are the androgens, of which testosterone is the most important. The androgens are steroid hormones produced mainly by the Leydig cells(interstitial cells located near the seminiferous tubules) of the Testes.
In humans, they are found in the seminiferous tubules of the testis. They carry out meiosis to produce spermatids, which in turn give rise to mature sperm cells. The spermatocytes are of two forms: the primary and secondary. The primary spermatocytes carry out meiosis I giving rise to secondary spermatocytes. The secondary spermatocytes perform meiosis II giving rise to haploid spermatids. The spermatocytes are the male counterpart of oocytes in female.
