Abstract

Macroscopic and histological analyses of the ovarian cycle of Crotaphytus collaris were conducted during 1971 and 1972. The reproductive season extends from April to late June; examination of ovarian histosections revealed two distinct sets of corpora lutea, indicating that two clutches of eggs are produced per season. The average clutch size was 6.4. Corpora lutea regress into permanent ovarian scars (corpora albicantia). Consequently, corpora albicantia may be used to estimate total reproductive potential for an animal. In addition, two types of atretic follicles were staged according to their degenerate morphology. The similarity and persistence of these ovarian structures (atretic follicles and corpora albicantia) may limit the value of macroscopic interpretations.
