Reaction to a study showing the efficacy of a male oral contraceptive in mice

A study in mice found that a molecule called TDI-11861 works as an oral male contraceptive, temporarily blocking sperm function. The paper, published in Nature Communications, presents the research as a step towards an on-demand male contraceptive drug: the user could take a birth control pill before sex and become fertile again the next day. Four co-authors of the study have founded a company in the US to develop such products.
