A semen analysis test is a medical procedure that evaluates different aspects of a man’s semen and sperm. The purpose is to see whether the sperm count, form, and motility are healthy. The test can identify potential fertility problems in the male partner.
However, the semen analysis only provides one part of the complex fertility picture. A couple’s ability to conceive also depends on factors like the woman’s health, genetics, lifestyle choices, and age. Nevertheless, comprehensive testing and analysis of the man’s semen gives couples struggling with infertility useful information to better understand their situation on the male side. This test assists them in making personalized decisions about options for starting a family.

Why Doctors Can Prescribe Semen Analysis
A doctor can advise this test when a couple has not started a family for six to twelve months, especially if the wife is over thirty-five years of age. A semen analysis performed on the man can reveal any sperms anomalies right from the start and assist in the right fertility treatments if required.It may also be recommended to investigate potential causes of infertility if a patient has risk factors that could impact sperm production, or to confirm the success of a vasectomy procedure. Overall, semen testing is a standard step in fertility evaluation that provides valuable information to diagnose and address issues.
How to Get Ready for Semen Analysis?
- Schedule the test with your doctor or a fertility clinic when you want to have your sperm count test.
- Abstain from sexual activity for 2-5 days before collecting the sample and any activity that leads to ejaculation. This allows sperm counts to build up to reflect accurate numbers.
- Keep the collection container at body temperature before producing the sample. The clinic or lab should provide a sterile specimen cup for collecting semen. Make sure it stays warm; putting it in an inside pocket for an hour before the test ensures a proper temperature. Cold temperatures can impact the motility of sperm.
- Make sure to collect the entire semen sample for examination. This gives the most complete data about your sperm count and semen quality. Discarding any portion may exclude important information.
- Record the time of ejaculation and abstinence periods. This provides essential data to interpret your results accurately.
- Deliver the sample immediately after collection. Get the specimen to the clinic promptly, within 1 hour, to prevent inaccurate results. Keep at body temperature during transport.
How Semen Analysis Is Performed
Sample Collection
When ready to provide the sample, the man masturbates and ejaculates into a clean, wide-mouth cup or container. It is preferable to attract a sample from the clinic or from the laboratory. In that manner, the sample is not spoiled during sample collection as it might cool or heat up depending on the location of the transport vehicle, hence, its capacity to swim.
Initial Macroscopic Examination
The fresh, untreated semen sample is first checked for:
- Viscosity – how thick or thin it is;
- Volume – amount ejaculated;
- pH – acidity or alkalinity;
- Liquefaction – how long it takes to liquefy;
- Color – normal is grayish-white;
- Presence of debris or blood.
Motility of Sperm
The technician then examines the semen sample under a microscope in order to determine what proportion of the sperm gives the impression of being motile. The technician also closely evaluates the quality and vigor of the movement displayed by the sperm. Healthy, strong mobility is an important factor in the sperm’s ability to reach and fertilize the egg.
Sperm Concentration
Sperm Morphology
The technician prepares a stained smear from the semen sample and then also examines the sample under the given microscope. Special attention is paid to the measurement of the size and form of sperm. In ideal samples meant for conception, at least 4% of sperm will have normal morphological forms. Abnormal shapes and sizes can mean defects that impede the sperm’s motility and navigation abilities.
White Blood Cell Count
A high level of white blood cells detected in the semen could signify an infection. Infection can often negatively impact fertility.
Other Tests
The laboratory also cultures samples of the semen to test for infections that could be present. Antisperm antibody tests check for antibodies that attack sperm.
What Are Normal Results?
The lab report details all test results along with reference values. Your doctor interprets the results.
Semen Analysis Test Normal Report
It is considered that a normal semen analysis should show such parameters as:
- Shape: Healthy sperm have an oval head and long tail, which helps them move. Over 85% of sperm should have a normal shape. Abnormally shaped sperm may have two heads, two tails, a crooked tail, or a large head.
- Movement: At least 50% of sperm should have good forward movement. This helps them reach and fertilize the egg. Poor movement can prevent conception.
- pH: Semen is an alkaline mixture and typically has a normal ph of 7.2-8.0. This tells one that an abnormal pH can mean one thing: infection or blockage.
- Volume: The normal semen volume per ejaculate is 1.5-5 milliliters (mL). Low volumes below 1.5 mL can indicate low sperm production or blockages.
- Liquefaction: Semen starts out gelatinous and liquefies over 15-30 minutes after ejaculation. Delayed or failed liquefaction can impact sperm health.
- Sperm count: A normal sperm concentration is 15 million sperm per milliliter (mL) or more. Counts between 15-100 million per mL are optimal for fertility. Counts under 15 million (oligospermia) or a lack of sperm (azoospermia) can cause infertility.
Abnormal results on any parameter may require treatment or lifestyle changes.
Healthy Sperm vs Unhealthy Sperm Color
Normal semen color is whitish-gray. Yellow, green, or red semen may reflect infections, blood in the ejaculate, or other abnormalities.
Total Sperm Count Normal Range
The World Health Organization defines a normal total sperm count as 39 million per ejaculate or more. Counts between 39-300 million are considered normal. A low sperm count is called oligospermia.
Conclusion
While a single test does not define absolute fertility prospects, this simple, low-cost analysis of sperm count, shape, and movement delivers vital information to identify obstacles and guide next steps. Abnormal semen results enable understanding of deficiencies and personalized weighing of medical or assisted reproduction options to optimize chances of pregnancy. Though male fertility is complex, semen testing illuminates one critical piece of the intricate fertility puzzle. For couples struggling with infertility, a comprehensive male fertility test equips them to better comprehend their situation and thoughtfully create a family
