Sperm production

Sperm production, known as spermatogenesis, occurs in the male testes. It begins at puberty and continues throughout life. The process involves germ cells dividing and maturing into sperm cells over about 64 to 75 days. Initially, spermatogonia multiply and then transform into primary and secondary spermatocytes, which eventually develop into mature spermatozoa. Each sperm cell carries genetic information and comprises a head, midpiece, and tail, enabling it to swim. Hormones, particularly testosterone, play a key role in regulating sperm production, ensuring a constant supply for potential fertilization of an egg.
