Asian rhino pregnancy at zoo another first (The Cincinnati Enquirer)- Topic: Pregnancy News

Nikki, a 15-year-old Indian rhinoceros at the zoo, is pregnant, the result of the world’s first successful artificial insemination procedure in an endangered rhino species. Her pregnancy at Cincinnati Zoo & Botanical Garden is also the world’s first in any rhino using frozen and thawed semen. Monica Stoops, reproductive physiologist at the zoo’s Lindner Center for Conservation and Research of Endangered Wildlife (CREW), supervises the project. She and her colleagues had to invent tools to collect the semen, then develop a technique for freezing and thawing, then invent more tools and techniques for intra- uterine implantation. The semen samples Stoops collected from 2002 to 2005 were kept at 323 degrees below zero in the Frozen Zoo and Garden in the CREW building. read more
