Sauna, heat, and the fundamentals of trying to conceive. What the evidence says about protecting fertility while you use heat.

Male Infertility and Depression: What the Research Really Shows
Male FertilityEmotional Health
I spent a weird amount of last winter reading studies on male infertility and depression. Not because I had to. Because something about the usual explanation kept bugging me.Every fertility clinic website, every health podcast, every men's wellness article tells the same story: infertility is stressful, stress makes you depressed, and that depression makes everything worse. It's a clean one-way arrow. It's also incomplete.What the deeper research suggests is messier, more interesting, and honestly more useful. Infertility and depression might not be cause and effect at all. They might be... Read more...
The Surprising History of Conception Advice—and Why the Every-Other-Day Rule Isn’t Always Right
Male FertilityClaims Examined
If you are trying to conceive, you have probably heard the standard advice: have sex every other day during the fertile window. Maybe you have also heard the older version: “save up” for a few days to build your sperm count. Or maybe a friend told you to have sex daily for better odds.The truth is, advice on how often to have sex for conception has changed a lot over the centuries. And most of it was never based on good science. The every-other-day rule is actually a recent invention,... Read more...
The Fertility Clinic Most Men Walk Into Wasn't Built for Them
Male FertilityStatistics & Trends
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...
What Plastic Is Doing to Your Hormones and Fertility—What the Research Actually Says
Male FertilityEndocrine Disruptors
I was twelve when my dad handed me a plastic water bottle and told me to refill it from the tap before soccer practice. I used that same bottle for two years. The bottom had a number 7 stamped into it-polycarbonate, which leaches BPA when heated. Nobody told us that back then. Nobody knew.Twenty years later, the research is hard to ignore. The average Western man carries measurable levels of plastic-derived chemicals in his urine, blood, and tissues. Those chemicals interact with his hormones. And the epidemiological data shows a...

What I Learned Watching Men Turn Infertility Support Groups Into Research Teams
Male FertilityMicroplastics
I spent the last few months digging into infertility support groups for men. Not because I was looking for a story about men learning to open up and talk about their feelings. I went in expecting something closer to that. What I found was something else entirely.There were guys sharing full PDFs of studies from journals like Human Reproduction Update. Someone had built a spreadsheet tracking phthalate levels in different protein powders. Another guy spent his Saturday cross-referencing his city's water quality reports against sperm motility data from a paper... Read more...
What Our Great-Grandfathers Knew About Fertility That We’ve Forgotten
Male FertilityHeat & Fertility
Let’s start with a number that should stop you cold: global sperm counts have dropped more than 50% over the last 50 years. That comes from a 2017 meta‑analysis by Levine and his team, which pulled data from 42,000 men across 50 countries. The decline isn’t slowing. We’ve been told to wear loose boxers, avoid hot baths, and eat more oysters. That’s not wrong, but it’s reactive. It treats the symptom, not the environment that created it.I’ve spent years digging into the research on male fertility-heat, environmental toxins, diet, sleep,... Read more...
The New Rules of Male Fertility: What the Best Specialists Are Asking Now
Male FertilityStatistics & Trends
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...
What Your Great-Grandfather's Sunlight Habits Could Teach You About Sperm Health
Male FertilitySperm Health
Finnish men who sauna four to seven times a week have a 40% lower risk of dying from heart disease. Danish men with higher vitamin D levels have better sperm motility. Two different countries, two different angles on health, but the same thread runs through both: what you expose your body to-heat, light, nutrients-shapes how well your cells work.I spent weeks digging into the vitamin D and male fertility connection. Not because I'm a doctor, but because the numbers kept showing up in the research. Men in northern Europe have... Read more...
The Right Way to Talk to Your Doctor About Male Fertility (No Awkwardness Required)
Male FertilityStatistics & Trends
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...
What Your Semen Analysis Doesn't Tell You (And Why That Matters)
Male FertilitySperm Health
I spent three months buried in semen analysis studies. Not because I was trying to conceive. Because I couldn't make sense of what I kept hearing from fertility clinics against what the research actually said.Here's what I found: the standard semen analysis-the one your doctor orders, the one with the neat reference ranges printed on the lab report-tells you less than most people believe. And what it misses might matter more than what it catches.Let me be clear: I'm not a doctor. I'm a guy who reads the studies so... Read more...
