Leading the way in fertility support for men
At Nexys Fertility, our mission is to provide comprehensive support for men facing fertility challenges. We envision a world where men are no longer left out of the conversation when it comes to fertility.
Derived from the Latin word ‘Nexus,’ our name represents connection — a central point where people, resources, and support converge.
We’re here to end the isolation faced by men experiencing fertility struggles. Through expert guidance, mental health support, and tailored lifestyle plans, our mission is to empower men to take control of their fertility journey.
Meet the Founders behind NeXYS Fertility
Founded by Ciaran and Shaun, who both faced their own fertility struggles, NeXYs was created to address the unique challenges men face. We provide tailored resources, expert guidance, and a supportive community — offering the help we wished we'd had.
Shaun Greenaway is a Male Fertility Coach, advocate, and co-founder of NeXYs Fertility.
When it comes to male infertility, Shaun has been there, got the t-shirt (and the scars too). Having been diagnosed with Azoospermia, he experienced the heartache, shame and secrecy attached to being a man with no sperm.
Shaun found himself navigating this trauma alone, with no support networks in place for men at the time - something that he became determined to change.
Now the proud father to twins conceived via the use of donor sperm, Shaun began his mission to break the stigma of male infertility by sharing his story via Instagram (@Knackered_Knackers).
To further expand the help and support he could provide men going through fertility struggles, Shaun trained to become an accredited Transformational Coach, and he has helped many men navigate the struggles.
He and Ciaran also co-host The Male Fertility Podcast - a podcast help support and educate men going through any kind of fertility issue.
Ciaran Hannington is a Male Fertility Coach, advocate, and co-founder of NeXYs Fertility.
In 2012, Ciaran’s life was turned upside down when a fertility consultant told him he was deemed infertile. This news shattered Ciaran, triggering a battle with his mental health as he faced isolation, grief, and feelings of inadequacy.
Repeated failed ICSI attempts and a heart breaking miscarriage only deepened his struggle.With his wife’s support, Ciaran focused on what he could control: his health. Using his background in Sport and Exercise Science he designed a health and fitness programme to optimise his health and give his sperm a much needed boost.
In 2016, his son Sebastian was born after a final ICSI attempt, and in 2020, Ciaran and his wife welcomed their daughter Enya into the world. Ciaran now supports other men facing infertility as The Male Fertility PT. Ciaran experienced first-hand that male infertility is more than a physical challenge, it’s an emotional one too, which men often faced in silence.
After launching The Male Fertility Podcast with his friend and co-host Shaun, together they founded NeXYs Fertility, creating a platform to provide men with the support, resources, and guidance need to navigate fertility.
