#24 – Reimagining male contraception – L.R. Fox – NEXT Life Sciences

How would the world look like if men had the most efficient and reversible means of birth control?

The outstanding work that L.R. Fox and his team at NEXT Life Sciences are leading might bring a very tangible answer to this question.

Based on the pioneering work from Prof. Sujoy K. Guha and The Parsemus Foundation, they are developing one of the most promising male birth control methods medicine has ever known, under the name of Plan A.

As an American citizen who has grown under the Foster Care program, Fox (as he likes to be called) has witnessed firsthand the dramatic consequences that unplanned pregnancies can have on individuals and their relatives in the long term.

According to him, we have gone quite far already in terms of available options for women and men when it comes to birth control methods. But Plan A could be a revolution in the space, as it is completely hormone-free, painless to deliver and revert, and has an efficacy duration that is way beyond current standards.

And most importantly, it can redistribute the heavy responsibility of family planning from women to men.

In this episode, we talk about the science behind Plan A, where the technology comes from, how far is it from being available worldwide, and what it would change for society as a whole!

A fascinating conversation with a visionary founder, deeply led by the purpose of fostering a positive impact in the world, and with a strong social approach to entrepreneurship!
