Electroejaculation and semen analysis in the La Plata three-banded armadillo (Tolypeutes matacus)
Abstract 10.1002/zoo.10053.abs The objectives of this study were to: 1) develop an electroejaculation procedure for collecting semen from the La Plata three-banded armadillo (Tolypeutes matacus), and 2) characterize basal reproductive traits, including sperm concentration, motility, morphology, acrosomal status, and viability. Three male armadillos were each electroejaculated on one to five occasions. Fluid containing spermatozoa was […]
Semen collection and analysis in the conservation of endangered nonhuman primates
Abstract 10.1002/zoo.1430080507.abs In-depth investigations are needed on methods of semen collection and analysis in endangered nonhuman primates. Due to lack of resources, zoos need the assistance and support of universities and primate centers to perform these investigations. Several collection methods are described. Penile and rectal probe electrical stimulation methods for semen collection are compared. Rectal […]
A review of the reproductive physiology of rhinoceros species in captivity
Substantial progress in understanding the reproductive physiology of the four rhinoceros species in captivity, White rhinoceros Ceratotherium simum, Black rhinoceros Diceros bicornis, Indian or Greater one-horned rhinoceros Rhinoceros unicornis and Suma-tran rhinoceros Dicerorhinus sumatrensis, has been achieved over the last two decades largely owing to advances in endocrine and ultrasound techniques, and improved methods of […]
