Final answer:
FSH stimulates spermatogonia to begin spermatogenesis, a process that involves mitosis followed by two rounds of meiosis to form haploid sperm cells.
Step-by-step explanation:
FSH, or follicle-stimulating hormone, stimulates the mitotic division of spermatogonia to begin the process known as spermatogenesis. This mitosis leads to the production of two identical, diploid daughter cells called primary spermatocytes.
These cells will eventually undergo meiosis to produce haploid cells required for reproduction. Spermatogenesis is a multistep process that occurs within the seminiferous tubules of the testes. After the primary spermatocytes are formed, they undergo meiosis I to produce haploid secondary spermatocytes, and following meiosis II, the secondary spermatocytes become spermatids, which will mature into fully functional sperm.
