Spermatogenesis in mammals involves the production of spermatocytes from the stem cell lineage, the spermatogonia. Spermatocytes undergo two meiotic divisions to generate haploid spermatids. Spermatids undergo differentiation during spermiogenesis to generate spermatozoa. Spermatozoa have three main regions: the head, midpiece and tail. In which region would you expect to find the mitochondria?
1 answer
The mitochondria in spermatozoa are typically found in the midpiece region. The midpiece contains a high concentration of mitochondria, which provide the energy required for sperm motility and survival.
