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

The Quiet Revolution in Men’s Fertility: Why Tracking Apps Are Finally For Us, Too
Male FertilityApps & Tracking
Fertility tracking apps designed specifically for men are now a real category, covering everything from lifestyle logging to at-home sperm analysis, though the evidence that tracking itself improves pregnancy rates is still limited and the technology is ahead of the science.Five years ago, if you searched for “fertility tracking app” in the App Store, every result showed a calendar with pink flowers and ovulation predictions designed for women. The assumption was clear: fertility is a woman’s problem. Men just show up.That’s changed. If you’re a guy in his thirties trying... Read more...
Sperm Analysis vs Semen Analysis: Two Names, Two Different Questions
Male FertilitySperm Health
Semen analysis is a full system test of the entire ejaculate, covering both the sperm and the fluid environment they travel in, while sperm analysis usually refers to the sperm-specific portion of that evaluation, covering count, motility, and morphology. They're often used interchangeably in everyday conversation, but what gets tested and reported can differ meaningfully depending on the setting.If you have ever been told to “get a sperm analysis,” there is a decent chance the person meant “semen analysis,” and an equally decent chance the lab meant something more specific....

Testosterone Supplements for Fertility: The Awkward Reality That “More T” Can Shut Sperm Down
Male FertilityTestosterone
Testosterone supplements don't reliably support fertility and can actively work against it. Taking testosterone from outside the body signals the brain to reduce its own hormonal output, which can lower sperm production and in some men push sperm counts to zero.Men usually don’t search “testosterone supplements for fertility” because they’re chasing a bigger number on a blood test. They’re trying to stack two goals at once: feel better day to day and improve the odds of a pregnancy. The problem is that testosterone sits in a weird spot in male... Read more...
Acupuncture for Male Fertility: What I Learned After Reading Every Study I Could Find
Male FertilitySperm Health
Research shows acupuncture can modestly improve sperm motility and morphology in some men, with biological mechanisms involving blood flow, oxidative stress, and hormone production offering plausible explanations, though effects are small rather than dramatic and it works best alongside standard medical care rather than as a replacement for it.I went into this research expecting to roll my eyes. Acupuncture for male fertility? I figured I’d find a handful of small, shoddy studies and a lot of wellness bloggers making claims they couldn’t back up.I was wrong about part of that....

When Trying for a Baby Wrecks Your Head, and Your Head Wrecks the Process: Mental Health and Male Infertility
Male FertilityEmotional Health
Mental health and male infertility tend to form a two-way feedback loop: the fertility struggle drives anxiety, low mood, and relationship strain, and those mental health hits then spill into sleep, libido, erections, and follow-through on the plan, which can reduce the odds of conception even when sperm numbers haven't changed dramatically.A semen analysis gives you a set of numbers. It does not show what your nights look like, how tense sex has gotten, or how much mental bandwidth this has started to take up. For a lot of men,... Read more...
Semen Analysis: The Male Health Check You're Ignoring
Male FertilitySperm Health
A semen analysis measures sperm concentration, motility, morphology, and volume, and research shows those numbers reflect your metabolic health, oxidative stress load, sleep quality, and even your long-term mortality risk, making it one of the most informative health screenings a man can get, not just a fertility check.If you've ever held a semen analysis report in your hands, you probably scanned for one number: is it high enough to get someone pregnant? That's fair. That's why most men get the test in the first place.But after months of digging into... Read more...
Preconception Planning for Men: The 90-Day Runway, and the Heat Problem Nobody Counts
Male FertilitySperm Health
Male preconception planning centers on a 90-day runway because sperm take roughly 2 to 3 months to be made and mature, meaning the habits you build today shape the sperm involved in conception weeks from now. Heat is the most overlooked variable in that window, quietly degrading sperm quality through everyday routines most men never consider.Thinking about having a kid? Preconception planning isn't just your partner taking a prenatal and tracking cycles. Men bring half the DNA, and the quality of that DNA is shaped by what your body has... Read more...
Your Varicocele Isn't a Plumbing Problem—It's a Broken Thermostat
Male FertilitySperm Health
A varicocele isn't simply a tangle of broken veins, it's a failed cooling system. The enlarged, faulty veins let warm blood from the abdomen flow backward, keeping the testicles chronically overheated and disrupting the lower temperature the body needs for healthy sperm production.If you've gone down the rabbit hole researching varicocele surgery, you've heard the standard line. It's a plumbing fix: swollen veins get tied off, blood flow improves, and fertility might follow. That's not wrong, but it's incomplete. After digging through the research, a clearer story emerges. This isn't... Read more...
Beyond the Surgery: What Every Man Should Know About Varicocele Repair
Male FertilitySperm Health
Varicocele repair addresses faulty veins that raise testicular temperature and harm sperm, but it does nothing about the chemical and environmental stressors that compound the damage, so every man who goes through the procedure needs a long-term plan to protect what the surgery creates.If you're looking into varicocele repair, you've likely been handed a simple story. Swollen veins cause overheating, overheating hurts sperm, and fixing the veins fixes the problem. The medical flowchart is clear: consider microsurgery or embolization, then move on. But after spending months sifting through reproductive science... Read more...
The Invisible Fight: What's Really Dragging Down Male Fertility
Male FertilityEndocrine Disruptors
Male fertility is being dragged down by a constant, low-level exposure to endocrine disrupting chemicals in the air, food, and home environment that mimic or block natural hormones, quietly interfering with sperm production long before most men realize anything is wrong.Let's talk about a number that doesn't lie: 51.6%. That's the average global drop in sperm concentration since the late 1970s. You've seen the headlines. You've heard the usual suspects—stress, processed food, never getting off the couch. Those matter, but they're only part of the story. After digging through the... Read more...
