Study Notes
Spermatogenesis
- Spermatogonia that lose contact with the basement membrane undergo developmental changes and differentiate into primary spermatocytes after crossing the blood-testis barrier
- Primary spermatocytes are diploid, having 46 chromosomes
- Primary spermatocytes replicate their DNA and initiate meiosis I
- Meiosis I results in the formation of two secondary spermatocytes
- Each secondary spermatocyte has 23 chromosomes, the haploid number (n)
