Where is the sperm cell?

Answer 1

In humans, there are specialized cells in the testes called spermatogonia (specifically in the basal compartment of the seminiferous tubules). It divides to form two primary spermatocytes. These move up into (a different part of) the seminiferous tubules, duplicates its DNA and divides by meiosis (reduction division) to form haploid secondary spermatocytes. Each divides and forms sperm, so there are four from each spermatogonia
