Anatomy of oviducts and sperm storage structures in lizards
MetadataShow full item record
This study was undertaken with the following objectives: (l) to conduct an exploratory survey for the presence of seminal receptacles in a variety of lizard species; (2) to test the fertilizing capacity of stored sperm in the seminal receptacles; (3) to make a detailed examination of the vaginal portion of the oviduct. Recent studies have directed much attention to discussions of the seminal receptacles and have neglected accurate description of the vagina where the receptacles have been found (Saint Girons, 1962; Fox, 1963). Earlier studies of the anatomy and histology of oviducts have been relatively superficial, particularly in descriptions of the vaginal segment (Brooks, 1905; Giersberg, 1922).
