The short version. A male fertility workup usually moves through five steps: a medical history, a physical exam, one or more semen analyses, hormone blood tests, and sometimes imaging. Each step narrows down whether there is a problem and, if so, what kind.
- It starts with history and a physical exam, including a check for a varicocele.
- The semen analysis is the centerpiece, often repeated.
- Hormone testing looks at testosterone, FSH, and LH.
- Imaging or genetic tests are added only when the earlier steps point to them.
If a semen analysis comes back abnormal, or you and your doctor decide to look deeper, the next step is a fuller male fertility workup. It sounds intimidating, but it is mostly a logical sequence of low-stress tests, each one answering a specific question. Here is what to expect, step by step.
Step 1: history
The workup starts with a conversation. A urologist or fertility specialist will ask about your medical and reproductive history: how long you have been trying, past pregnancies, childhood issues like undescended testicles, prior surgeries or injuries, infections, medications, and lifestyle factors like smoking, alcohol, heat exposure, and anabolic steroid use.
This step often surfaces the cause on its own, or at least points the rest of the workup in the right direction. Be candid here, especially about steroid or testosterone use, since that alone can explain a low count.
Step 2: physical exam
Next is a focused physical exam. The main things the doctor is checking for:
- A varicocele, enlarged veins in the scrotum, which is one of the most common and treatable causes of low sperm quality.
- Testicle size and consistency, which can indicate how well they are producing sperm.
- The vas deferens, to confirm the tubes that carry sperm are present and normal.
- Any structural issues that could point to a blockage.
It is quick and not invasive, and it frequently identifies something the history hinted at.
Step 3: semen analysis
The semen analysis is the centerpiece, and it is usually repeated, because results vary between samples and one reading is not a diagnosis. If you have already done an at-home mail-in analysis, that result is a useful starting data point to bring to the appointment. What the analysis measures, count, motility, morphology, and total motile count, is detailed in the male fertility testing guide.
An at-home analysis is a strong way to walk in with data already in hand, which can speed the conversation.
Walk in with your numbers
The Jack At-Home RSA Semen Analysis gives you a full panel to bring to your appointment, count, motility, total motile count, and morphology, from a CLIA-certified, CAP-accredited lab. $249, results in 1 to 2 days.

If the semen analysis is abnormal, a blood test checks the hormones that drive sperm production, typically testosterone, FSH (follicle-stimulating hormone), and LH (luteinizing hormone), and sometimes prolactin and others.
The pattern of these hormones tells the specialist a lot. It can distinguish a problem with the testicles themselves from a signaling problem higher up, and it can flag a hormonal cause that is directly treatable. This is also where undisclosed testosterone use tends to reveal itself.
Step 5: imaging and specialized tests
Depending on what the earlier steps show, the workup can add targeted tests:
- Scrotal ultrasound to confirm a varicocele or look for a blockage.
- Genetic testing when the count is very low or absent, since some cases have a genetic basis.
- Sperm DNA fragmentation testing in specific situations, such as recurrent pregnancy loss.
- Post-ejaculate urine testing if retrograde ejaculation is suspected.
These are not routine. They are added only when the history, exam, semen analysis, and hormones point toward a specific question.
What comes out of it
The goal of the workup is a cause and a plan. Depending on findings, that might mean treating a varicocele, correcting a hormonal issue, changing a medication, addressing lifestyle factors, or, in some cases, moving toward assisted reproduction. The point is that most findings lead somewhere actionable. When to start this process in the first place is covered in when to see a fertility doctor.
FAQ
What does a male fertility workup involve? Usually a medical history, a physical exam, one or more semen analyses, hormone blood tests, and, when indicated, imaging or genetic testing.
Is the physical exam invasive? No. It is a quick external exam checking for a varicocele, testicle size, and the vas deferens, similar to a routine genital exam.
Why do they repeat the semen analysis? Because results vary between samples. Repeating avoids drawing a conclusion from a single low or borderline reading.
Can I bring an at-home test result to the appointment? Yes, and it helps. A prior lab-analyzed result gives the specialist a data point to start from and can speed the conversation.
Will I need genetic testing? Only in specific cases, mainly when the count is very low or absent. It is not part of a routine first workup.
