ST. LOUIS Apr 28, 2005 — Three yapping, cuddly South American bush dog pups at the Saint Louis Zoo are making fertility history among wild canids, with implications for the rest of the animal world.
Youngsters Mariana, Turi and Sherman, resembling chubby, furry, Chihuahuas, were born in January following a successful, first-of-its-kind vasectomy reversal on the pups’ father. The procedure was performed in August 2003 by St. Louis infertility specialist, Dr. Sherman Silber, a 15-year zoo consultant, who perfected it on more than 4,000 humans before trying it on Brent, the bush dog.
