Sperm storage in Hemidactylus mabouia: morphological and ultrastructural aspect...
Sartori, Sirlene Souza Rodrigues; Nogueira, Katiane de Oliveira Pinto Coelho; Araújo, Vinícius Albano; Neves, Clóvis Andrade; Kolisnyk, BenjaminSperm storage is a common phenomenon in most female reptiles. Evidence of sperm storage is based on the observation that female fertilization occurs even when females are separated from males, as well as the presence of agglomerates of spermatozoa in specific regions of the oviducts. Lizards are capable of storing sperm in the uterine tube, vagina, or in both regions. However, representatives of the Gekkonidae ...
