Dr. Turek Awarded an NIH Grant to Build Artificial Testicle
Proposal to make human sperm from stem cells receives government funding
San Francisco – January 9, 2012. Dr. Paul Turek, Director and Founder of The Turek Clinic, a men’s health medical practice, and Dr. Constance John, chief executive of MandalMed, Inc, a San Francisco-based biotech company, were recently awarded a Small Business Innovation Research (SBIR) grant from the National Institute of Environmental Health Sciences (NIEHS) of the National Institutes of Health (NIH) to construct an artificial human testicle and research how sperm are made from stem cells.
“Fertile sperm can be made from various stem cells in mice, but making human sperm from these same sources has been elusive,” says Turek, a practicing male infertility specialist in San Francisco. In this project, they will try to produce mature human sperm in a live laboratory model of a human testicle.
We have assembled a great group of scientists who are very committed to its success.”

This work extends on previously published research by Dr. Turek on human testicular stem cells, the forerunners of sperm. Dr. John is an expert on human Sertoli cells, which critically nurture sperm as they develop in the testicle. “This grant is quite an honor and comes after several years working together on this idea,” notes Turek. “We have assembled a great group of scientists who are very committed to its success.”
A functioning artificial testicle has important implications for the field of reproductive biology. It could shed enormous light on the intricate details behind the mysterious and complicated process of spermatogenesis or sperm production. Even further, it could be used to later develop patient-specific, fertile sperm for men who simply do not make sperm due to genetic or acquired causes.
