A semen analysis is one of the most informative and least invasive tests in all of men’s health. From a single sample, it reveals how many sperm are present, how well they move, and how they are shaped, offering an early and objective picture of fertility potential. For couples beginning to understand why pregnancy hasn’t happened, it is often the logical starting point and a natural companion to a broader male fertility evaluation.
Dr. Justin Houman is a board-certified urologist, Fellow of the American College of Surgeons, and fellowship-trained microsurgeon in Male Reproductive Medicine and Surgery, training he completed at UCLA Medical Center. As an Assistant Professor of Urology at Cedars-Sinai Medical Center in Los Angeles, he interprets semen analysis results the way a reproductive specialist should — in full clinical context, connecting the numbers to the larger picture of a man’s reproductive and overall health.

What Is a Semen Analysis?
A semen analysis is a laboratory test that examines a sample of semen under a microscope to assess the health and quantity of sperm. Results are compared against established World Health Organization reference values, giving Dr. Houman an objective basis for evaluating fertility potential. The test looks at several key characteristics:
- Sperm count, or the concentration of sperm in the sample
- Motility, or how well the sperm move
- Morphology, or the size and shape of the sperm
- Semen volume, pH, liquefaction time, and other supporting measures
Reasons a Semen Analysis May Be Recommended
While most men associate the test with fertility, a semen analysis serves several distinct purposes:
Fertility Evaluation
It is typically one of the first steps when a couple has had difficulty conceiving.
Post-Vasectomy Confirmation
It verifies that no sperm remain after a vasectomy before the procedure is relied upon for contraception.
Treatment Baseline
It establishes a starting point before therapy and helps measure progress afterward.
Ongoing Monitoring
It tracks changes in sperm health over time when a known condition is being managed.
What to Expect From Your Semen Analysis
Preparation matters, because several everyday factors can influence a sample. Dr. Houman generally recommends abstaining from ejaculation for two to five days beforehand, avoiding alcohol, and disclosing any medications, supplements, or hormones, since these can affect results. A sample can be provided privately in the office or collected at home and delivered within about an hour, kept at room temperature and free of lubricants that could contaminate it. The sample is assessed in the lab, often with results available within a day. Because sperm counts naturally fluctuate, Dr. Houman may repeat the analysis a few weeks later to confirm findings before drawing any conclusions.

Meet Dr. Houman
Expert in Men’s Health with Tower Urology and Cedars Sinai
Dr. Justin Houman, MD, FACS is a board-certified urologist and fellowship-trained microsurgeon at Tower Urology, Cedars-Sinai Medical Center in Los Angeles. His subspecialty training in male reproductive medicine and microsurgery is held by fewer than 2% of practicing urologists in the United States.
His clinical focus is narrow by design. Varicoceles, chronic testicular pain, male infertility, vasectomy, testosterone optimization, erectile dysfunction, penile implant surgery, and Peyronie’s disease are not add-on services here. They are the practice. Patients travel from across the country and internationally for procedures, particularly microsurgical varicocelectomy, spermatic cord denervation, and inflatable penile implant surgery, that require a level of subspecialty training and surgical volume most urology practices do not have.
