As mentioned above, spermatogenesis is the process by which sperm cell production occurs; the germ cells give rise to the haploid spermatozoa. Sperm production takes place inside the
When does spermatogenesis take place?
Spermatogenesis is initiated in the male testis with the beginning of puberty. This comprises the entire development of the spermatogonia (former primordial germ cells) up to sperm cells. The gonadal cords that are solid up till then in the juvenile testis develop a lumen with the start of puberty.
When does spermatogenesis begin and end?
Spermatogenesis takes approximately 70 days, therefore in order for sperm production to be continuous and not intermittent, multiple spermatogenic processes are occurring simultaneously within the same seminiferous tubule, with new groups of spermatogonia arising every 16 days (spermatogenic cycle).
