What is an andrologist?

Andrology is the branch of medicine devoted to male reproductive health, male hormones, and male sexual function. The name comes from the Greek word for man. Where gynecology covers the female reproductive system, andrology covers the male one.

The symmetry stops at the training system. Gynecology has its own American residency and its own board. Andrology does not. In the United States this care lives inside urology, which is already the surgical specialty responsible for the male reproductive organs.

So the practical definition is straightforward. An American andrologist is a urologist whose practice concentrates on male fertility, sexual function, and testosterone. The word describes what the doctor focuses on, not a separate license.

Search a US hospital website for "andrologist" and you will often get nothing back. The doctor you want is usually two clicks away under a different heading. Health systems here market the service line, not the Greek root.

The word is standard in much of Europe, Latin America, the Middle East, and South Asia. Many countries recognize andrology as its own specialty or subspecialty with its own certificate. Patients who move to the United States, or who read international health content, keep using the term that made sense at home.

That mismatch has a real cost. Men are told to "see an andrologist," search for one, and find nothing local. The care exists in every large American city. It is simply filed under men's health, male sexual medicine, or reproductive urology.

Knowing the mapping is the single most useful thing on this page. Once you search the department name instead of the job title, the specialist becomes easy to find.

The path starts with four years of medical school. Next comes a urology residency of five to six years, which includes general surgery training and covers the entire urinary tract in men, women, and children (AUA).

After residency, some urologists complete a fellowship of one to two years in andrology, male reproductive medicine, or sexual medicine. This is the step that produces the doctor most people mean by "andrologist." Fellowship training in this area is associated with the Sexual Medicine Society of North America and the American Society of Andrology.

Board certification is through the American Board of Urology. There is no separate American board certificate in andrology, so certification in urology is the credential to verify. The ABMS certification lookup will show whether a urologist is currently certified.

Fellowship is what adds the microsurgical and prosthetic skills. Microsurgical vasectomy reversal, microsurgical varicocelectomy, testicular sperm extraction, penile prosthesis implantation, and Peyronie's reconstruction are learned in that extra year or two, not in general residency.

The conditions fall into four groups. Fertility comes first: abnormal semen analysis, low sperm count, azoospermia, varicocele, prior vasectomy, and fertility preservation before cancer treatment.

Sexual function is the second group. That includes erectile dysfunction, Peyronie's disease, premature and delayed ejaculation, painful ejaculation, blood in the semen, and priapism.

Hormones are the third. Low testosterone, also called hypogonadism, is the common entry point. An andrologist evaluates the cause rather than only replacing the hormone, which matters because standard testosterone therapy suppresses sperm production.

Structural and surgical problems make up the fourth group. Penile prosthesis surgery, Peyronie's reconstruction, varicocele repair, vasectomy and vasectomy reversal, and sperm retrieval procedures all sit here.

Every American andrologist is a urologist. The reverse is not true. Urology is the broader specialty, and andrology is the male reproductive and sexual slice of it.

A general urologist handles a great deal of andrology every week. Vasectomy, first-line erectile dysfunction treatment, an initial testosterone workup, and a first semen analysis are routine general urology work. You do not need a fellowship-trained specialist to start.

The escalation triggers are specific. No sperm in the ejaculate, a planned vasectomy reversal, sperm retrieval for IVF, a penile implant, complex or recurrent Peyronie's disease, priapism, or erectile dysfunction that failed medication and injections all point to fellowship training.

There is also a volume argument. Microsurgery and prosthetic surgery reward experience. Asking how many of a specific procedure a surgeon performs each year is a fair and useful question.

The word has a second meaning inside fertility clinics, and it causes real confusion. In many American IVF laboratories, the andrologist is the laboratory scientist who prepares, analyzes, and freezes semen samples.

That person is not a physician and does not diagnose or treat patients. They run the semen analysis, perform sperm washing and preparation for insemination or IVF, and manage cryopreservation. Their certification path runs through laboratory and bioanalysis credentialing, not through a medical residency.

This explains why "is an andrologist a doctor" is one of the most searched questions on the topic. Both answers are correct depending on the setting. If a fertility clinic says the andrologist will call about your sample, they usually mean the laboratory.

For a treatment decision you want the physician. Ask directly whether you are being scheduled with a urologist or with laboratory staff.

Endocrinologists treat hormone disorders across the whole body, including pituitary, thyroid, adrenal, and diabetes care. They may manage testosterone, and they are the right choice when a pituitary problem or a broader endocrine disease is suspected. They do not perform urologic surgery or fertility microsurgery.

Reproductive endocrinologists are obstetrician-gynecologists who treat the female partner and run IVF cycles. They frequently work alongside a male-side specialist rather than replacing one. If a couple is in IVF, both doctors are often involved.

Primary care physicians and online men's health services can order first labs and prescribe first-line erectile dysfunction medication. That is a reasonable starting point. It is not a substitute for evaluation when sperm counts are abnormal, when fertility is a goal, or when surgery is on the table.

One caution is worth stating plainly. Testosterone therapy started without a fertility conversation can suppress sperm production, sometimes for a long period. Men who may want children should raise that before beginning treatment.

Expect a detailed history. The doctor will ask about symptom timeline, previous pregnancies or attempts, surgeries, infections, medications, supplements, anabolic steroid or testosterone use, and cardiovascular risk factors.

A physical examination follows, including a genital and scrotal exam. Testicular size and consistency, the presence of a varicocele, and whether the vas deferens is present are all findings that change the plan.

Testing is targeted rather than universal. Semen analysis, morning testosterone with confirmatory hormone labs, and scrotal ultrasound cover most first workups. Genetic testing and specialized sperm-function testing are reserved for selected situations.

Bring records. Prior semen analyses, hormone results, imaging reports, operative notes, and a current medication list often prevent a wasted appointment.

Start with the department name rather than the job title. Search a health system for men's health, male sexual medicine, or reproductive urology, then read the physician biographies for fellowship training.

Verify credentials next. Confirm board certification in urology through the ABMS lookup, then confirm the fellowship in andrology, male reproductive medicine, or sexual medicine. Membership in SMSNA or the American Society of Andrology is a useful supporting signal.

Then match the doctor to the problem. Microsurgery and prosthetic surgery are the two areas where fellowship training and annual volume matter most. For a first ED or testosterone conversation, a general urologist can begin the work.
