The uncomfortable truth about male fertility decline (and the research-baked solution)

There isn’t one single reason for the drop in sperm counts — it’s a mix of everyday habits and hidden exposures that quietly take a toll. Modern life has become a slow, steady stressor on reproductive health.

A few of the biggest factors:

• Endocrine-disrupting chemicals: BPAs and phthalates (common in plastics and food packaging) can interfere with hormone balance and sperm development.
• Heat exposure: Laptops on laps, long hot-tub sessions, even heated car seats can reduce sperm production over time.
• Nutrient gaps: Diets heavy in processed foods and sugar often miss the specific micronutrients sperm need to form and mature properly.
• Lifestyle stressors: Poor sleep, chronic stress, and regular alcohol or cannabis use can all lower sperm count, mobility, and shape.

It’s a perfect storm — one that’s left many men without clear answers or resources. SwimClub was created to change that.

That frustration and lack of guidance is exactly what Dr. Michael Eisenberg, a top urologist and Director of Male Reproductive Medicine and Surgery at Stanford, decided to fix.

“Sperm quality is declining at a rate we can’t ignore,” says Dr. Eisenberg. “That’s why I partnered with SwimClub to develop the first sperm performance supplement based on decades of research and clinical experience.”

SwimClub is the first clinically-formulated, expert-driven protocol that directly addresses this crisis.

“Most supplements are built on generic formulas,” Dr. Eisenberg adds. “SwimClub is different. It’s formulated to target the root causes of suboptimal sperm health, using bioactives at clinical levels sourced from the best manufacturers in the world.”

At the core of SwimClub is its Spermatogen™ Complex. The complex is delivered in daily capsules and softgels to maximize bioavailability, featuring powerful, research-backed ingredients at clinically-backed dosages:

• Omega-3s (EPA/DHA): Helps keep sperm flexible and mobile.
• Coenzyme Q10 (CoQ10): Powers the mitochondria: the tiny engines inside each sperm that drive movement.
• L-Carnitine: Helps transport fat into sperm mitochondria, where it’s turned into energy.
• Lycopene: Effective at countering damage from heat and toxins.
• Vitamin D3: Regulates testosterone levels and supports sperm function
• Methylfolate: Supports DNA synthesis and cell division.

SwimClub is not an overnight fix. It’s a 90-day protocol because it’s designed to optimize the entire sperm production cycle.
Here’s what happens during Spermatogenesis: sperm are formed from stem cells in the testicles, a phase that takes roughly 72 days.

Then, they spend another 10–14 days maturing in the epididymis, gaining the ability to swim and fertilize an egg.

That cycle can’t be rushed.

SwimClub gives your body the nutrients it needs to support sperm at every stage, so each new cycle starts with a stronger foundation.

SwimClub was born out of frustration. A group of founders who faced their own fertility challenges and wanted better answers. They combined years of research, expert insight, and real-world results to create a protocol that actually reflects how sperm health works.

Whether you’re trying to conceive or simply want to understand your reproductive health better, SwimClub offers a way to take a more proactive, informed approach.
