What is spermatogenesis?

What is spermatogenesis?

• A. Process by which sperm are produced by the male.
• B. Condition in which one or both testicles remain in the body cavity.
• C. Process by which ova are produced by the female.
• D. Causes destruction of the cotyledons of the uterus.

Answer: (A)

Spermatogenesis is the formation of sperm cells in the male reproductive system. It takes place in the seminiferous tubules of the testes, where germ cells undergo mitotic divisions and two rounds of meiotic divisions to become haploid spermatozoa. Sertoli cells support and nourish developing sperm, while Leydig cells produce testosterone that drives the process, under hormonal control (LH and FSH). The mature sperm then move to the epididymis to finish maturation and gain motility. This concept is distinct from other options: producing ova is oogenesis and occurs in the female; a condition where testicles remain in the body cavity would affect sperm production due to temperature but is not the definition of the process; and destruction of cotyledons relates to placental structures, not sperm formation.
