Study Notes
Gametogenesis
- Process of forming and developing gametes, with a reduction in chromosome number by half.
Spermatogenesis
- Transformation of spermatogonia to spermatozoa, starting at puberty.
- Spermatogonia reside in the seminiferous tubules of the testes.
- Undergo several mitotic divisions, maturing into primary spermatocytes.
- Primary spermatocytes enter first meiotic division to produce secondary spermatocytes.
- Secondary spermatocytes complete a second meiotic division, forming spermatids.
- Sertoli cells line the seminiferous tubules, providing support and nutrients to germ cells.
Spermiogenesis
- Series of transformations from spermatids to spermatozoa.
- Formation of the acrosome, which has enzymes for ovum penetration during fertilization.
- Nucleus condenses significantly.
- Development of neck, middle piece, and tail structures.
- Most cytoplasm is shed during maturation process.
- Full development of a spermatozoon from a spermatogonium takes about 64 days.
- Spermatozoa are moved toward the epididymis, where they gain complete motility.
