Injectable Male Contraceptive Gel Effective in Rabbits: Study

An injectable male contraceptive gel was effective in rabbits, researchers say.

The flow of sperm was blocked after an injection of Vasalgel, and resumed after the gel was removed, United Press International reported.

The gel would provide a non-permanent birth control alternative to vasectomy, according to the authors of the study in the journal Basic and Clinical Andrology.

The researchers are planning to start a human clinical trial late this year, UPI reported.
