Duration of spermatogenesis

DURATION OF SPERMATOGENESIS

Entire spermatogenesis takes about 50-60 days in boars, 60-70 days in bull and ram.

  • Spermatogenesis comprised of four to five cycles of seminiferous epithelium.
  • Cycle of seminiferous epithelium is defined as series of stages/changes between two similar cellular associations in the given area of seminiferous tubule.

The time necessary to complete a cycle of the seminiferous epithelium is called duration of spermatogenesis and varies among domestic animals

Spermatogenic wave

The distance between two similar cellular associations in the seminiferous epithelium is called spermatogenic wave.
