In 1985, a man whose semen analysis came back low often got a pat on the back and a suggestion to try again in a few months. If he asked to see a male fertility specialist, the front desk might not know what that meant. The field barely existed. A urologist might run a basic analysis between prostate exams and kidney stone consults. The couple's care usually centered on the woman. The man got a cup, a room, and a form letter with results.
That world is gone. Male factor infertility now shows up in roughly half of all infertility evaluations, and the people who handle it have split into subspecialties with different training paths and different standards. The problem is that the title fertility specialist tells you almost nothing about what kind of care you will get. A reproductive urologist and a reproductive endocrinologist are different clinicians. So the filter comes down to three things. Know the credentials, know what a real workup looks like, and know which questions expose the difference.
The strange history: why male fertility care lagged
The first real breakthrough in understanding male fertility came in 1951, when researchers figured out sperm could survive freezing. Sperm banks followed in the 1960s. But clinical care stayed thin. The turning point arrived in 1978 with IVF. By the 1990s, intracytoplasmic sperm injection meant a lab could take a single viable sperm and inject it into an egg. That changed the incentives. Why investigate why a man had low counts if the lab could bypass the problem? The money and attention shifted to the female partner's ovaries and uterus because that is where the embryo lab made its revenue. Male evaluation became a gatekeeper step: produce a sample, get a number, proceed to IVF.
The subfield of male reproductive medicine only started getting serious academic attention in the late 1990s and early 2000s. Fellowships in andrology and male infertility became more common. Urology departments began producing clinicians who did nothing but male fertility all day. The consequences of that delay still show up in clinics. Many general urology offices still approach male fertility as a lab test plus a referral, not as a diagnosable condition with its own exam and hormonal interpretation.
The three types of specialists
Three types of physicians routinely treat male fertility issues. Each brings a different skill set.
- Reproductive urologists are urologists who completed a fellowship specifically in male infertility and microsurgery. They evaluate anatomical causes, do testicular mapping for sperm retrieval, perform varicocele repairs, and reconstruct blockages from prior vasectomies or injury. If the problem is structural or obstructive, this is the person.
- Reproductive endocrinologists are trained in hormonal causes of infertility. Many focus on the female side, but some handle male hormonal evaluation. They can review bloodwork and address hormonal imbalances. They do not do the surgical side. Think of them as the hormone experts.
- General urologists and general practitioners sometimes run semen analyses and call themselves fertility-focused. Many do not have the training to do a full male workup. You would not ask a general contractor to run your electrical. Similar logic.
So the first question when booking is narrow and specific. Ask whether the male team completed a fellowship in male fertility or andrology and whether they interpret semen samples themselves. You might feel awkward asking. Do not. The front desk hears versions of this every week. Andrology is a clinical field with standards, not just a lab test.
What a proper workup actually includes
A complete male fertility evaluation is not a semen analysis plus a handshake. It should include a history that asks specific things most men have never been asked about: childhood undescended testicles, mumps after puberty, hernias, prolonged chemical exposure, prior hormone use, supplements in the last six months, sauna or hot tub use, tight jeans, occupational heat exposure, cycling volume, and whether you ever sat with a laptop directly on your lap for years.
One study that gets quoted often, by Garolla and colleagues in Human Reproduction back in 2013, found that regular sauna-level heat temporarily lowered sperm count and made morphology worse. The changes reversed after heat exposure stopped. Sperm production needs the testicles a few degrees cooler than core body temperature. A specialist who never asks about heat, occupational or recreational, is missing a basic part of the history.
The physical exam should include testicular volume measurement with an orchidometer, not a guess. Low volume is a useful clinical finding. Scrotal examination for varicocele, done lying and standing with and without Valsalva, matters. So does checking for epididymal abnormalities, inguinal scars, and prostate issues.
The lab work is where gaps appear. A complete panel measures follicle stimulating hormone, luteinizing hormone, total testosterone, estradiol, and prolactin. Some clinicians add sex hormone binding globulin, free testosterone, thyroid studies, and DNA fragmentation. Ordering is not the issue. Interpretation is. High FSH with low sperm count suggests testicular failure. Normal FSH with low sperm count suggests something upstream, maybe a blockage or pituitary issue. The pattern matters more than any single number.
The semen analysis itself varies by lab. The World Health Organization updated its semen reference values again in 2021. A lab still using older criteria might call a sample normal when a current one would not. The lab should do strict morphology scoring, not loose estimates. Some clinics outsource semen analysis to labs that process samples late in the day. Motility and viable count drop as the clock runs.
Questions that separate real care from a sample mill
Ask these without feeling like a difficult patient.
- Do you evaluate and treat male factor separately from our IVF plan, or is the male side mostly handled through the lab? This one question reveals the model. If the answer is that the female partner's doctor will handle the male side, understand that the clinic likely views you as a sample source, not a patient with a diagnosable condition. A reproductive urologist evaluates and treats the man directly.
- Will my semen sample be collected on site and analyzed within an hour? Sperm motility drops measurably after about an hour. Collecting at home for a baseline is fine with proper transport, but the clinic should give you a kit and tell you to keep the sample at body temperature, not in the glovebox and not in the fridge.
- Do you do DNA fragmentation testing, and what do you do with the result? DNA fragmentation testing measures how much DNA inside the sperm head is damaged. High DNA fragmentation has been associated with lower pregnancy rates and higher miscarriage rates in some studies with natural conception and IVF. The clinical guidance is still evolving. What matters is whether the specialist can explain when the test is useful and when it is not. A blank stare tells you something. A three-minute explanation of SCSA, TUNEL, and COMET assays tells you something else.
Do not overvalue DNA fragmentation either. Some clinics market it to every patient. The test has real value for unexplained infertility and recurrent pregnancy loss, not as a universal screen.
The shift from volume to precision
The biggest change I have noticed in the last five years is the move away from total motile count as the master number. It still matters for choosing between timed intercourse, intrauterine insemination, and IVF with ICSI. But clinics that treat the man as a real patient now do more upstream investigation.
There is a growing recognition that poor semen parameters often travel with other health conditions. The research connecting semen quality to broader cardiometabolic health keeps stacking up. The best male fertility doctors act like the first doctor a man has seen in ten years. They check blood pressure, cholesterol, glucose. They ask about sleep, alcohol, exercise, and sleep apnea. The fertility problem is the doorway. The real health workup is the room.
Genetics has also become standard. Karyotype, Y chromosome microdeletion, and CFTR testing for congenital absence of the vas deferens are no longer exotic. A specialist who does not bring genetics into the discussion is behind.
Then there is the environmental piece. Sensitive analytical methods have now detected microplastics in human testicular tissue and semen. Studies published in 2023 and 2024 found microplastics in testicular and semen samples. The presence is real and measurable. What researchers cannot tell you yet is whether that presence drives lower fertility, because the human data are associations. A current specialist will know the literature and ask about occupational exposures, plastic food packaging, and personal care products. A specialist who rolls their eyes at environmental exposures is telling you about their reading habits.
What a specialist cannot do
Some men walk in expecting a specialist to fix everything with a prescription and a protocol. Fertility medicine has real limits. If the tubules contain no germ cells at all, no doctor and no supplement will change that. If a Y chromosome microdeletion affects the AZFa or AZFb region, sperm retrieval generally fails. If a man has suppressed sperm production from prior hormone use, recovery often takes months and is not guaranteed.
A good specialist gives you the honest ceiling. One of the most valuable things a reproductive urologist can tell you is not that he can fix everything, but what the evidence says is possible in your specific case and what is not. If you sit with a doctor who only tells you what you want to hear, you are not getting medical care. You are getting sales.
A practical filter in four steps
- Seek out a fellowship trained reproductive urologist if any of these apply: azoospermia or counts below 5 million per milliliter, a history of testicular injury or surgery, a varicocele on exam, prior vasectomy, recurrent pregnancy loss, or unexplained infertility with a normal female evaluation. The training difference is real.
- Verify the basics before booking. Does the clinic have an on-site andrology lab with same-day analysis? Will you see the physician directly for the first consult and physical exam? A nurse practitioner or physician assistant can be excellent for follow-up, but the first visit should be with the person making decisions.
- Ask about the physical exam and hormone panel directly when you book. If the receptionist says the clinic does not do testicular volume or hormone testing, that is not evasion. That is information. Thank them and call the next place.
- Go in with your history prepared. Prior surgeries, childhood issues, medications, supplements, exercise routine including sauna and cycling, occupational heat exposure. Bring your partner if she is in the picture. The male evaluation and female evaluation are two halves of one conversation.
Where the field is heading
The pace of change right now is real. Single cell RNA sequencing is revealing subpopulations of sperm precursors that were invisible ten years ago. Epigenetic and proteomic analysis of semen is moving from research into early clinical use. At-home sperm testing has matured into a useful triage tool, though it cannot replace a lab analysis. The microplastics and endocrine disruptor work is forcing fertility medicine to think about environmental exposure histories as standard intake. And the link between male fertility and overall health is pushing andrologists to become, oddly enough, the first real primary care many men ever get.
The specialist you pick is not just reading a sperm count. The good ones are thinking about you as a man with a body, a history, and a future. That is the standard to search for.

Frequently asked questions
what kind of doctor should a man see for fertility testing
A fellowship trained reproductive urologist is the most complete option, especially if counts are very low, a varicocele is present, or there is a history of testicular injury or vasectomy. Reproductive endocrinologists can handle hormonal evaluation, and general urologists can run baseline tests, but their depth of male-specific training varies.
what does a full male fertility workup include
A proper workup includes a detailed history on heat exposure, prior hormone use, childhood issues, and medications, plus a physical exam with testicular volume measurement and a varicocele check. Bloodwork should cover FSH, LH, total testosterone, estradiol, and prolactin at minimum, and the semen analysis should be done on-site with strict morphology scoring.
is dna fragmentation testing worth doing
DNA fragmentation testing can be useful for unexplained infertility and recurrent pregnancy loss, but it is not a universal screening tool. The more important factor is whether the specialist can explain when the test is indicated and what the result would change in your specific case.
does sauna use affect sperm count
One of the established findings in the field, from Garolla and colleagues in Human Reproduction in 2013, is that regular sauna-level heat temporarily lowers sperm count and can worsen morphology. The effect appears reversible once heat exposure stops. A specialist who never asks about sauna or hot tub use is missing a basic part of the history.
