Human Chorionic Gonadotrophin Treatment for Sexual Immaturity in a Male Ibex (Capra Pyrenaica)
Journal Title: Veterinary Medicine – Open Journal - Year 2017, Vol 2, Issue 2
Abstract
Gonadotrophin deficiency, a condition usually present from birth, can cause delayed puberty in humans and domestic animals, but this has not been confirmed in wild mountain ruminants. During the rutting season (December), signs of sexual immaturity were detected in a 2.5 yearold male Iberian ibex (Capra pyrenaica) maintained in captivity. Cryptorchidism of the right testicle was diagnosed, along with complete adherence of the urethral process to the prepuce. The animal was treated with five injections of 500 UI hCG, administered intramuscularly over four weeks (two injections four days apart in the first week, and then one injection per week). Upon completion of the treatment, the right testicle completed its descent into the scrotum, and the urethral process detached from the preputial mucous membrane. A semen sample was collected which revealed oligoasthenospermia, confirming hCG to be at least partially effective in the stimulation of spermatogenesis in ibexes with gonadotrophin deficiency.
