My recent essay for Aeon Magazine discusses the development of newer male contraceptives which may offer a degree of reliability and reversibility similar to that of female contraceptives. Male hormonal contraceptives have been tested in small clinical trials since the 1970s, but none of them have been approved for general use. Research funding agencies and pharmaceutical companies need to make the necessary investments and forge partnerships so that the stalled research in male contraception can be revitalized.
It is a fascinating area of research and I hope you enjoy reading the Aeon Magazine essay.
I also encourage you to also read some of the original references to learn more about the research. Here is a list of key references and a couple of informative websites:
