Researchers at São Paulo State University (UNESP) in Brazil have studied a protein in sperm and discovered two new targets that can be used in combination to develop male contraceptives. The study also demonstrates the feasibility of using mice as a model for in vivo trials during the drug development process. Scientists interested in the protein have so far used primates in their experiments, making the trials more complex, time-consuming and costly.
