Ultrasound imaging of reproductive organs and eggs in Galapagos tortoises, Geochelone elephantopus spp
Abstract 10.1002/zoo.1430090503.abs This study demonstrates the efficacy of using ultrasound to determine the presence of ovarian developing, preovulatory, and atretic follicular structures and oviductal eggs in the Galapagos tortoise, Geochelone elephantopus spp. Ultrasound was effective in locating both right and left ovarian structures in 92% (n = 100 ovaries) of the trials. Developing and preovulatory […]
Observations on the female reproductive cycle of captive giant tortoises (Geochelone spp.) using ultrasound scanning
The reproductive activities of one adult female Galapagos tortoise (Geochelone nigra) and three adult female Aldabra trotoises (Geochelone gigantea) were monitored over 2 yrs using ultrasound scanning. A nonrestraining technique o tactile stimulation was used for all examinations. Developing, preovulatory, and atretic ovarian follicles, as well as eggs at various stages of shell deposition, were […]
