Essential tests for male infertility: What to expect?
20 December 2024Essential tests for male infertility: What to expect?
Male infertility is a common issue that affects many couples trying to conceive. While female infertility is often the focus, male infertility plays a significant role in about 30-40% of infertility cases. To identify the root causes, various tests are essential for diagnosing male infertility. Understanding these tests and what to expect can help reduce anxiety and provide clarity in your fertility journey.
- Semen analysis.
- Physical examination
- Hormone testing.
- Ultrasound examination.
- Genetic testing.
- Sperm DNA fragmentation test.
1. Semen analysis
What it is: The first and most essential test in evaluating male infertility is a semen analysis. This test measures the quantity, quality, and movement (motility) of sperm in the semen.
What to expect:
- Procedure: The test requires the collection of a semen sample. The sample is typically obtained through masturbation in a private room at the clinic or at home using a sterile container provided by the clinic. In some cases, a special condom may be used during intercourse to collect the sample.
- Procedure: The test requires the collection of a semen sample. The sample is typically obtained through masturbation in a private room at the clinic or at home using a sterile container provided by the clinic. In some cases, a special condom may be used during intercourse to collect the sample.
- Parameters checked:
- Sperm count: The number of sperm present per milliliter of semen.
- Sperm motility: The ability of the sperm to move effectively.
- Sperm morphology: The shape and structure of the sperm.
- Semen volume: The total amount of fluid ejaculated.
- pH level: The acidity or alkalinity of the semen.
- Liquefaction time: The time it takes for the semen to change from a gel-like consistency to a liquid form.
- Presence of white blood cells: Indicates potential infections or inflammation.
- Sperm count: The number of sperm present per milliliter of semen.
Why it’s important: A low sperm count, poor sperm motility, or abnormal sperm morphology can significantly impact fertility. Semen analysis is often repeated to confirm results, as sperm quality can fluctuate due to various factors like stress, lifestyle, or illness.
2. Physical examination
What to expect:
- Procedure: The doctor examines you by examining testis , penis and other reproductive organs.
- Procedure: The doctor examines you by examining testis , penis and other reproductive organs.
- Parameters checked:
- Testis size: Small size testis have less number of sperm producing cells leading to reduced sperm count.
- Sexual characteristics: Suboptimal Male pattern hair growth and musculature may suggest hormonal imbalances.
- Presence of varicocele: Varicocele of Enlarged veins in the scrotum that can impair sperm quality and production. If severe enough it can be felt during examination.
- Vas and epididymis: Thickening of Vas and fullness of epididymis may suggest infection , inflammation or blockage.
- Testis size: Small size testis have less number of sperm producing cells leading to reduced sperm count.
Why it’s important: It helps in identification of the cause of infertility and design a potential treatment plan.
3. Hormone testing
What it is: Hormone testing evaluates levels of key reproductive hormones that regulate sperm production and male reproductive function.
What to expect:
- Procedure: A blood test is performed to measure hormone levels, including:
- Testosterone: The primary male sex hormone responsible for sperm production.
- Luteinizing Hormone (LH): Stimulates testosterone production in the testes.
- Follicle-Stimulating Hormone (FSH): Encourages sperm production.
- Prolactin: Elevated levels can indicate hormonal imbalances or pituitary gland issues.
- Estradiol: High levels may suggest hormonal disturbances.
- Testosterone: The primary male sex hormone responsible for sperm production.
Why it’s important: Abnormal hormone levels can signal dysfunction in the hypothalamus or pituitary gland, which control sperm production. For example:
- Low testosterone may indicate reduced sperm production possibly due to inadequate signal from brain (if FSH level is low or normal)
- Elevated FSH can suggest testicular failure or impaired sperm production.
- Addressing hormonal imbalances can improve fertility outcomes.
4. Ultrasound examination
What it is: Ultrasound imaging is used to identify structural or physical abnormalities in the male reproductive organs.
What to expect:
- Procedure: A non-invasive test where a transducer (a handheld device) emits high-frequency sound waves to create images of the scrotum, testes, and surrounding structures. The test is usually performed externally on the scrotal area.
Why it’s important: Ultrasound can detect conditions such as:
- Varicocele: Enlarged veins in the scrotum that can impair sperm quality and production.
- Testicular atrophy: Shrinking of the testes.
- Blockages: Obstructions in the vas deferens or epididymis that hinder sperm transport. Diagnosing these physical issues helps determine appropriate treatments, such as surgery or assisted reproductive techniques. Usually blockages are difficult to diagnose on ultrasound.
5. Genetic testing
What it is: Genetic testing identifies genetic abnormalities that may contribute to infertility.
What to expect:
- Procedure: A blood sample or cheek swab is collected to analyze the genetic material (DNA).
Why it’s important: Certain genetic conditions can impair sperm production or function, including:
- Y-chromosome microdeletions: Missing genes necessary for sperm production.
- Klinefelter syndrome: A condition where males have an extra X chromosome.
- Cystic fibrosis mutations: Can cause congenital absence of the vas deferens (a tube that carries sperm). Identifying genetic factors helps in counseling couples about potential risks of passing genetic issues to offspring and determining treatment options.
6. Sperm DNA fragmentation test
What it is: This test assesses the integrity of sperm DNA, which is crucial for fertilization and embryo development.
What to expect:
- Procedure: A semen sample is collected and analyzed in a laboratory to measure the extent of DNA fragmentation.
Why it’s important:
- High sperm DNA fragmentation is associated with:
- Poor embryo quality.
- Recurrent miscarriages.
- Unexplained infertility. This test is recommended for couples experiencing failed IVF cycles despite normal sperm parameters.
- Poor embryo quality.
Conclusion
Male infertility can have a significant impact on a couple’s ability to conceive, but with the right tests, the causes can be identified and treated. Semen analysis, hormone testing, ultrasound, genetic testing, and more can help determine the best course of action. If you suspect infertility, consulting with a fertility specialist is crucial to find the right tests for your situation.

FAQs
The results of a semen analysis typically take 4 hrs to 1 day, but it can vary depending on the clinic or laboratory.
A urologist specializes in the male reproductive system and may conduct tests, provide a diagnosis, and recommend treatment options for male infertility. Although primary diagnosis is made by a fertility expert. Fertility expert should always be in the treating team as it is important to treat the couple, not just one partner.
Yes, lifestyle changes such as maintaining a healthy diet, reducing alcohol consumption, quitting smoking, and managing stress can help improve sperm quality.
A varicocele is an enlargement of veins within the scrotum that can affect sperm quality, while a hydrocele is a fluid-filled sac around the testes, which typically doesn’t affect fertility.
While the sperm DNA fragmentation test can provide important insights into sperm quality, it is not always definitive and is typically used in combination with other fertility tests.
Depending on the genetic condition, treatment options may include sperm retrieval methods, such as ICSI, or genetic counseling to guide future family planning. In cases of chromosomal rearrangements IVF with PGT-SR (Preimplantation Genetic Testing for Structural Rearrangements ) is helpful.
Hormone testing is a simple blood test and carries minimal risks. Some men may experience slight discomfort or bruising at the blood draw site.
