WebAnswer. Sperm production, otherwise known as spermatogenesis, occurs in the male testes in structures called the seminiferous tubules. Overall, spermatogenesis aims to convert diploid primary germ cells into haploid mature sperm cells, which are able to fertilize a female’s egg cell. WebSpermatogenesis refers to the formation of sperm, which is the male reproductive cell. Unlike the female reproductive cell, sperm are created continuously throughout the lifetime of the male after he reaches puberty. In fact, more than 100 million sperm cells can be produced in a single day!
