SwimClub™, a new male fertility supplement, has officially launched, offering the first clinically-formulated approach designed to improve sperm performance through evidence-based ingredients at therapeutic doses. The product comes as a single daily regimen or a subscription “SwimClub Box” to provide comprehensive support for men navigating fertility challenges.
Led by CEO Steve Zanette and developed by Squared Circles—a consumer health venture studio founded by Alexander Gilkes, Osman Khan, and Lukas Derksen—SwimClub aims to address a critical, often overlooked public health issue: male reproductive health.
A Silent Global Crisis
Experts describe a phenomenon known as “Spermageddon,” highlighting a 59% decline in sperm counts since 1973 and a sharp drop in testosterone levels since 2020. Additionally, the average age of first-time fathers has increased by four years since 1980. Despite men contributing to 50% of infertility cases, most solutions have historically focused on women, leaving male reproductive health under-addressed.
Dr. Michael Eisenberg, Chief Scientist at SwimClub and Professor of Urology at Stanford University, emphasized:
“Modern lifestyles—high stress, environmental toxins, and dietary shifts—have driven sperm counts to historic lows. SwimClub is the first product taking a clinically-informed, male-first approach to this urgent crisis.”
From Personal Experience to Clinical Innovation
For Osman Khan, co-founder of Squared Circles, the journey to creating SwimClub was deeply personal. He and his wife, Lauren, navigated a long, complicated fertility journey that involved over 20 different supplements, ultimately inspiring them to build a science-backed, simplified solution.
Steve Zanette echoed the sentiment, citing multiple miscarriages and limited options for men seeking to improve fertility:
“SwimClub is the product I wish existed during our journey—a clinically validated way for men to take control of their reproductive health.”
The SwimClub Solution
SwimClub’s proprietary Spermatogen Complex™ targets four critical sperm parameters: count, motility, morphology, and DNA integrity. Its formula includes 12 clinically-studied ingredients:
Omega-3 fatty acids (EPA & DHA): Enhance motility and membrane integrity.
Coenzyme Q10: Boosts ATP production and protects sperm from oxidative damage.
L-Carnitine: Supports motility and DNA quality.
Folate (5-MTHF): Reduces DNA fragmentation and supports genomic stability.
R-Alpha Lipoic Acid (R-ALA): Improves motility, morphology, and concentration.
Other key nutrients include zinc, Vitamin D, and Vitamin E, all contributing to oxidative stress reduction and enhanced spermatogenesis. Clinical data suggest consistent improvements in sperm quality over a 3-month supplementation period.
Real-Time Health Data and Advice
Recent studies indicate that nearly 40% of men aged 25–45 in North America have below-optimal sperm counts. Experts recommend lifestyle measures in parallel with supplementation:
Exercise regularly: Moderate physical activity boosts testosterone and sperm motility.
Maintain a balanced diet: Emphasize antioxidants, omega-3s, and whole foods.
Minimize toxin exposure: Limit smoking, alcohol, and endocrine-disrupting chemicals.
Manage stress: Chronic stress negatively affects sperm DNA integrity.
Dr. Eisenberg notes that combining lifestyle changes with clinically-formulated supplements like SwimClub offers men the highest likelihood of improving fertility outcomes.
