A semen analysis examines a fresh sample of ejaculate in an andrology laboratory. It measures the volume, the number of sperm, how many are moving and how well, and what proportion have a normal shape, together with acidity, liquefaction and signs of infection.
It is the first and most informative test of male fertility and guides the choice between natural conception, insemination, IVF and ICSI. It does not measure fertility directly: many men with values below the reference range father children, some with normal values do not, and results vary considerably from one sample to the next.
What Semen Analysis (Sperm Test) shows
Results are compared with World Health Organization reference limits, which are the lower fifth centile values of men whose partners conceived within a year: volume of about 1.4 millilitres, concentration of 16 million per millilitre, total count of 39 million, total motility of 42 percent, progressive motility of 30 percent and normal forms of 4 percent. The report may describe low count (oligozoospermia), poor movement (asthenozoospermia), abnormal shape (teratozoospermia) or no sperm at all (azoospermia). Low volume with acidic semen suggests a blockage or absent ducts. Many round cells or white blood cells raise the question of infection. Optional extras include sperm DNA fragmentation, antisperm antibodies and vitality staining.
When Semen Analysis (Sperm Test) is recommended
- Couples who have not conceived after 12 months of regular unprotected intercourse, or after 6 months if the woman is over 35
- Before any fertility treatment, to choose between IUI, IVF and ICSI
- Men with a history of undescended testes, testicular surgery, mumps orchitis, chemotherapy or a varicocele
- Before sperm freezing ahead of cancer treatment or vasectomy
- After vasectomy, to confirm absence of sperm, usually at 12 weeks
- After vasectomy reversal or varicocele repair, to monitor recovery
Limits and situations where another test is better:
- A single abnormal result should not be acted on; repeat it after 2 to 3 months, since sperm take about 10 weeks to form
- A recent fever, illness, hot tub use or anabolic steroid or testosterone use can temporarily depress results
- Home test kits only estimate concentration and miss motility and shape
- It does not explain the cause; abnormal results need hormone tests, examination, ultrasound and sometimes genetic tests
How to prepare
- Abstain from ejaculation for 2 to 7 days; shorter or longer intervals distort count and motility
- Avoid alcohol excess, saunas and hot baths in the preceding days, and mention any fever in the last 3 months
- Produce the sample by masturbation without lubricants or ordinary condoms, which harm sperm
- Collect the entire sample, and say if any part was lost, particularly the first portion
- If producing at home, keep the container at body temperature and deliver it within 60 minutes
What happens during the test
You are given a sterile, labelled container and a private room at the laboratory. The sample is left to liquefy for 20 to 30 minutes and then examined under the microscope within an hour, by a trained scientist or with computer-assisted analysis checked by hand. The visit takes about 30 minutes and involves no discomfort. If producing a sample on site is difficult, discuss alternatives beforehand.
Results and next steps
Basic results are often ready the same day or within 1 to 2 days; DNA fragmentation and culture take several days longer. A normal result shifts attention to the female partner's tests. An abnormal result is repeated, and the man is examined by a urologist or andrologist, with FSH, LH, testosterone and prolactin tests, scrotal ultrasound and, when the count is very low, karyotype and Y-chromosome microdeletion testing. Treatment ranges from lifestyle change and varicocele repair to ICSI or surgical sperm retrieval.
- Test time: About 30 minutes at the laboratory
- Results ready: Same day to 2 days
- Back to everyday activity: None
Safety and risks
- No physical risk
- Embarrassment or difficulty producing a sample under pressure
- Misleading results if abstinence or collection instructions were not followed
- Anxiety from a single borderline result that later proves normal
Arranging Semen Analysis (Sperm Test) in Türkiye
A semen analysis is simple and available everywhere, so do not travel for it alone. It is, however, the first step of any fertility visit to Istanbul and is usually repeated by the treating clinic even when you bring a result from home, because IVF laboratories prefer their own assessment. Men with azoospermia can combine the work-up with a planned sperm retrieval procedure on the same trip.
Send your previous reports and the question you want answered and a Clinic-Y coordinator replies within 24 hours with suitable teams and written, all-inclusive proposals side by side. Reviewing your case is free.
Frequently Asked Questions
My result is below the reference range. Am I infertile?
No. The ranges describe fertile men's lower limit, not a pass mark. Chances fall gradually as values fall, and the result has to be repeated before conclusions are drawn.
Can I improve my sperm?
Stopping smoking, reducing alcohol, losing excess weight, avoiding heat and stopping testosterone or anabolic steroids all help, with effects showing after about 3 months. Antioxidant supplements have weak evidence.
Is a sperm DNA fragmentation test worthwhile?
It may help after repeated IVF failure or miscarriage, or with a varicocele. It is not recommended as a routine first test.
What does azoospermia mean for us?
No sperm in the ejaculate. If the cause is a blockage, sperm can nearly always be retrieved surgically. If production has failed, micro-TESE finds sperm in roughly 40 to 50 percent of men.
