In episode 338, we welcome our guest, Will Matthews, the founder and CEO of Fellow, a company that’s rethinking the future of men’s fertility and runs the largest semen analysis lab in the U.S. In today’s episode, we’re covering the topic that men like to shy away from – sperm health! We start by discussing the decline in fertility rates in the West and the possible reasons why – stress, obesity, and chemical exposure. Then Will shares what it was like to create the first clinic grade direct-to-consumer semen analysis kit so you can avoid that awkward doctor’s visit. As we wind down, Will shares his vision of creating a flywheel effect, using test data to conduct research and in turn use that research to fine-tune their test kits.
