As 2023 comes to a close, we’re looking back at the breakthroughs, research, and media moments that pushed male fertility into the spotlight. From new studies to national TV coverage, here are five exciting developments that made waves this year.
Sperm Health on Channel 4
This year, male fertility got a prime-time TV moment with Channel 4’s Celebrity Save Our Sperm! The show followed Russell Kane, Ollie Locke, and Melvin Odoom as they tested and worked to improve their sperm health over 10 weeks.
It raised awareness of the importance of sperm testing and explored some of the key reasons for declining sperm counts — including toxins in our environment. Each celebrity saw measurable improvements after making lifestyle changes. Ollie Locke even went on to become a dad! We hope this national conversation inspires more men to take charge of their fertility health.
ExSeed Launches CASA Lite
2023 was also a major year for ExSeed. We launched CASA Lite, our latest innovation in semen diagnostics. While our home sperm test empowers men to test their fertility privately, CASA Lite was built for professionals. It allows clinics, GPs, and other healthcare providers to perform fast, accurate semen analyses anywhere with an internet connection.
The portable device uses Computer-Assisted Sperm Analysis (CASA) technology to deliver results in as little as one minute. Combining high-resolution imaging with powerful AI-based analysis, CASA Lite is transforming the way fertility professionals work. Want to see it in action? Visit our CASA Lite page to book a demo.
New Research: Mobile Phones and Male Fertility
We’ve talked for years about how heat and tech can affect sperm health, and in 2023 a new study from the University of Geneva offered strong evidence of the link between mobile phone use and lower sperm concentration.
Researchers studied 2,886 Swiss men aged 18–22 between 2005 and 2018. They found that men who used their phones more than 20 times per day had an average sperm concentration of 44.5 million per millilitre. In contrast, those who used their phones less than once a week had 56.5 million per millilitre — a 21% difference.
These results highlight how frequent phone use might contribute to lower sperm quality. While the findings are concerning, they also open the door for more research to uncover the mechanisms behind this trend. We’re hopeful 2024 brings even more progress in this area.
Global Call for Urgent Male Fertility Action
Scientists didn’t just study male fertility in 2023 — they called for action. A global consortium of experts, led by Professor Moira O’Bryan from the University of Melbourne, urged governments to take male reproductive health more seriously.
In a paper published in Nature Reviews Urology, the group outlined a roadmap for urgent global intervention. Their recommendations included wider access to genomic sequencing, improved diagnostic testing, and stricter evaluation of endocrine-disrupting chemicals. Seeing such strong collaboration between international experts gives us hope for faster progress in understanding — and improving — male fertility worldwide.
Launch of The Male Fertility Podcast
Two of the UK’s most well-known voices in male fertility, Fertility Coach Shaun Greenaway and Personal Trainer Ciaran Hannington, joined forces this year to launch The Male Fertility Podcast.
Both men have shared their personal struggles with infertility online for years. Now, they’ve brought their experiences to a new platform — offering an honest and sometimes hilarious look at life during infertility. From awkward sperm sample stories to open conversations about emotional resilience, this podcast is a must-listen for men navigating similar journeys.
Listen to the podcast on Spotify, YouTube, or Apple Podcasts.
Looking Ahead to 2024
From media representation to scientific collaboration, 2023 was a year of real progress for male fertility awareness. We’re excited to see what 2024 brings — from new research breakthroughs to continued conversations that empower men to take control of their reproductive health.
