The Fertility Clinic Most Men Walk Into Wasn't Built for Them
You walk into a fertility clinic for the first time. The waiting room is pastel. The magazines are Parents and Fit Pregnancy. The intake form asks about your partner’s cycle length, ovulation history, and whether she’s had previous treatments. At the bottom, there’s a line for “male partner notes.” Maybe three inches of blank space.That small detail tells you everything about how most clinics think about men.I’ve spent months digging into fertility research, clinic protocols, and what actually happens when a couple walks through the door. What I found is... Read more...
The New Rules of Male Fertility: What the Best Specialists Are Asking Now
Ten years ago, if you walked into a fertility clinic with a low sperm count, the conversation went like this: “Here’s a list of supplements. Try to keep your laptop off your lap. Come back in three months.” That was about the extent of it.The best male fertility specialists today don’t do that anymore. They’ve started connecting dots that were sitting in plain sight for decades-between the environment a man lives in, the heat he exposes himself to, and the toxins his body processes. The shift hasn’t made headlines, but... Read more...
The Right Way to Talk to Your Doctor About Male Fertility (No Awkwardness Required)
You and your partner have been trying for months. Maybe a year. She's had blood drawn, tracked ovulation, peed on sticks, sat through ultrasounds. You've been supportive. But nobody has asked you for a sample.That silence isn't random. It's built into how medicine treats male fertility, and it's kept men from getting answers for decades. I've spent years digging into the research on sperm counts, heat exposure, endocrine disruptors, and clinical guidelines. I'm not a doctor. I'm a guy who reads the studies so you don't have to. Here's what... Read more...
Why Most Fertility Doctors Miss the Real Problem (And How to Pick One Who Doesn't)
I spent a month reading everything I could find on how men pick fertility doctors. The pattern was depressing. Most guys type "fertility clinic near me," click the first result with five stars, and call it a day. Some don't even bother seeing a doctor - they just hand their partner a cup and stay out of it.Here's what I dug up from medical journals, training program histories, and the actual numbers on male infertility: the system was never designed with you in mind. Male fertility has been treated like... Read more...
How the Modern World Broke Male Fertility—And What the Research Says About Fixing It
I spent a week reading through the literature on male infertility. What I found surprised me-not because the treatments are exotic or cutting-edge, but because of what they reveal about how drastically our environment has changed in the last fifty years.Sperm counts have dropped by more than half since the 1970s. That isn’t a niche finding from one lab in Denmark. It is a meta-analysis of 185 studies covering 42,000 men across North America, Europe, Australia, and New Zealand (Levine et al., 2017, Human Reproduction Update). The decline shows no...

Keto and Sperm: The Evolutionary Mismatch Between Fat-Burning and Fertility
A buddy of mine started keto last January. Lost 18 pounds in six weeks. Felt sharper mentally. Then he and his wife started trying for a kid. Six months passed. Nothing. His doctor ran labs and flagged low sperm motility. When he told me about it, the keto connection clicked because I'd been digging into how extreme carb restriction affects male reproduction.This isn't an anti-keto hit piece. I'm not here to tell anyone what to eat. But if you're a man in your twenties or thirties who might want children... Read more...
The Number That Keeps Moving: What Sperm Analysis Normal Ranges Really Mean
The normal range for sperm analysis keeps moving because the WHO sets its cutoff at the fifth percentile of men who recently fathered a child, and that reference population's average count has fallen with each new edition of the manual, dropping the threshold from 40 million per mL in 1978 to 15 million per mL by 2010.You get a semen analysis report back. The lab says your count is 18 million sperm per milliliter. Normal range? According to the current WHO reference, anything above 15 million is considered normal. So... Read more...
The Number That Keeps Moving: What Sperm Count “Normal” Actually Means (And Why It Changed So Fast)
The WHO's definition of a normal sperm count is a statistical snapshot based on the bottom 5 percent of today's fertile men, not a fixed biological standard, and it's dropped from 100 million per milliliter in 1973 to 15 million per milliliter in 2021 because the average man's sperm count has genuinely declined over those decades.In 1973, the World Health Organization said a normal sperm concentration was at least 100 million sperm per milliliter. By 2021, they had dropped that number to 15 million per milliliter.That is an 85 percent... Read more...
Why I Think Every Guy Under 35 Should At Least Get a Semen Analysis
Getting a semen analysis before you're trying to conceive gives you a real data point about your fertility while you still have time to act on it, and the research behind declining sperm quality across populations makes that case hard to ignore for men under 35.I’ll say it straight up: I’m not a doctor. I’m a guy who spent way too many weekends reading fertility studies and talking to urologists because I wanted to know what actually matters for men my age. What I found changed how I think about...

The Sperm Donor Screening That 98% of Men Fail—And What It Tells Us About Male Fertility
In 2022 the FDA reported that only about 2 percent of men who apply to become sperm donors are accepted, meaning roughly 98 percent are turned away. Screening happens in stages, from application and family history to semen analysis, so not every rejection is about sperm quality, but the low acceptance rate has drawn attention to broader pressures on male reproductive health.I spent two months reading through fertility clinic protocols, sperm bank application requirements, and the research on what happens to men who donate repeatedly. What I found surprised me.The... Read more...
