If a male is born with 3 million spermatogonia in each testis, the maximum number of sperms that he can produce in his lifetime is 24 million.

If a male is born with 3 million spermatogonia in each testis, the maximum number of sperms that he can produce in his lifetime is 24 million. Correct Answer False

One spermatogonium upon undergoing a process of spermatogenesis produces 4 haploid sperms. Thus 3 million spermatogonia in each testis which is a total of 6 million spermatogonia should indeed produce 24 million sperms if undergone meiosis. However, spermatogonia also undergo mitosis giving rise to many more spermatogonia by the age of puberty and even after that.
