The formation of male gametes or sperm cells is called spermatogenesis. This is a form a meiosis, in which four daughter cells are formed. The process takes places in the male reproductive organs, the testes. The female counterpart to this is called oogenesis, which produces one usable daughter cells, an oocyte or egg cell, (and three discarded cells called polar bodies) this process occurs in the ovaries.

spermatogonia
A gamete. It might be a bit too broad though. In animals the male gamete is always a sperm. In most flowering plants the male gamete is also called sperm.
Male sex cells (gametes) are known as spermatozoa - or simply sperm.
Interstitial cells of Leydig in the testes secrete testosterone.

Although only males produce sperm, that does not mean that all sperm is male. There are two types of sperm: male and female. Male sperm carry the 'y' chromosome; female sperm carry the 'x' chromosome. If all sperm where male, then there would be no females born. Thus, the difference between male and female sperm is that male sperm carries the 'y' chromosome and produces male offspring and female sperm carries the 'x' chromosome and produces female offspring.
