Study Notes
Spermatogenesis
- Sertoli cells are responsible for the differentiation of spermatids into mature spermatozoa.
- Sertoli cells function to provide nutrition and support to developing sperm cells, as well as phagocytose excess sperm cytoplasm.
Spermatocyte Development
- One primary spermatocyte produces four haploid mature spermatozoa.
Sertoli Cell Function
- Mullerian inhibitory factor (MIF) produced by Sertoli cells inhibits the development of Müllerian ducts in males, which would otherwise develop into female reproductive organs.
Spermatogenesis Timeline
- Spermatogenesis takes approximately 74 days to complete.
