Where are sperm formed?

Where are sperm formed?

• A. In the epididymis
• B. In the urethra
• C. In the seminal vesicles
• D. In the seminiferous tubules of the testes

Answer: (D)

Sperm formation happens through spermatogenesis in the seminiferous tubules of the testes. These tightly coiled tubules contain germ cells that divide and differentiate into mature sperm, with support from Sertoli cells and regulation by hormones like follicle-stimulating hormone and testosterone. After the sperm are formed, they move toward the epididymis, where they mature and gain motility. The epididymis, urethra, and seminal vesicles all play roles in transport, maturation, and seminal fluid production, but the actual production of sperm occurs in the seminiferous tubules.
