spermatogenic cycle
duration of the cycle which separates consecutive cell divisions of spermatogonia (pig is 8 days, sheep 10, cattle 14) to produce spermatocytes.
spermatogenic wave
spermatogenesis occurs in sequential waves along the length of the seminiferous tubules so that spermatozoa are produced in waves; the phenomenon which ensures that spermatozoa are produced continuously, except for seasonal pauses when spermatogenesis is initiated and terminated each year.
