When you think of fertility, you might automatically think of women’s fertility. But there are men online doing something called ‘fertilitymaxxing’ - it’s all about young men trying a bunch of unproven hacks in hopes of improving their sperm health.

Content with these hacks are often pushed by male wellness and manosphere influencers online - but is this really about raising more awareness of male fertility (which is an under-researched issue)? Or is it about other anxieties Gen Z men might have about their health - and masculinity more generally?

Jacqui Wakefield is our Global Health Correspondent and has been speaking to men, like Simon in Miami, who have been doing things like icing his testicles in a bid to boost sperm count. And also Professor Channa Jayasena, a reproductive endocrinologist and Imperial College, explains that some medicines these influencers are recommending can be very dangerous.
