The spermatogenic period refers to the time it takes for spermatogenesis, the process of sperm cell development, to occur in the male reproductive system. In humans, this period lasts approximately 64 to 72 days, during which spermatogonia develop into mature spermatozoa through several stages, including mitosis, meiosis, and spermiogenesis. This process continuously produces sperm throughout a male's reproductive life, with millions of sperm being generated daily.
