However, oogenesis and spermatogenesis occur at very different times during development and achieve different endpoints. In females, this process is initiated in the fetus well before birth, with the goal of forming a finite number of stored gametes that are used periodically over a defined reproductive lifetime.

At what age does spermatogenesis begin?

Males start producing sperm when they reach puberty, which is usually from 10-16 years old.

What is spermatogenesis and when does it occur?

Spermatogenesis is an ongoing differentiation process that occurs in the seminiferous epithelium in the testis in males to produce spermatozoa (sperm) and is sustained by a tissue-specific stem cell termed the “spermatogonial stem cell.”
