The Man Cave

“It is estimated that infertility affects 8–12% of couples globally, with a male factor being a primary or contributing cause in approximately 50% of couples.” (The Lancet)

The Man Cave is an organisation for men with fertility issues. Founder Kevin Button is working with Best Fertility Now, to provide resources and support to men who are facing fertility challenges.

The Man Cave focuses on men’s mental health and aftercare when they are going through infertility diagnosis and treatment. The organisation provides information aimed at all men, to help them to understand the challenges facing men with infertility.
