In a new paper published by Nature Communications, The Lundquist Institute (TLI) Investigator Wei Yan, MD, PhD, and his research colleagues spell out an innovative strategy that has led to the discovery of a natural compound as a safe, effective and reversible male contraceptive agent in pre-clinical animal models. Despite tremendous efforts over the past decades, the progress in developing non-hormonal male contraceptives has been very limited.
“Thanks to decades of basic research, which inspired us to develop the idea that a compound that targets a protein critical for the last several steps of sperm assembly would lead to the production of nonfunctional sperm without causing severe depletion of testicular cells,” said Dr. Yan. “We are very excited that the new idea worked and that this compound appears to be an ideal male contraceptive. Our results using non-injurious studies on lower primates suggest triptonide will be an effective treatment for human males as well. Hopefully, we will be able to start human clinical trials soon to make the non-hormonal male contraceptive a reality.”
“Dr. Yan’s discovery represents a major leap forward in the field,” said Drs. Christina Wang and Ronald Swerdloff, who are TLI co-Principal Investigators helping lead NIH-supported advanced clinical trials on hormone-based birth control approaches. “The more contraceptive methods available, the better, as we will want a family of pharmaceutical products to safely and effectively meet the family planning needs of men and couples at different stages of their reproductive lives, with differing ethnic, cultural and religious backgrounds and economic means,” emphasized Wang and Swerdloff.
