What is Semen Analysis?
Semen analysis is one of the most commonly performed tests during a male fertility evaluation. It examines a semen sample to assess important sperm parameters such as sperm concentration, motility, morphology, semen volume, and other characteristics. The test helps evaluate sperm production and overall sperm quality, which can play an important role in conception. Based on the results, a fertility specialist can identify possible sperm-related factors affecting fertility and recommend further evaluation or appropriate treatment when needed. In some cases, the test may be repeated to confirm the findings and assess consistency. The results can also help guide the choice of fertility treatment based on the individual’s reproductive health.
A standard semen analysis test or sperm test (semen test) done from a regular pathology laboratory reports mainly motility and concentration of sperms seen in the provided semen sample.
One of the most important characteristics of sperm is it’s morphology. It takes a trained technician and appropriate equipment to comprehend the abnormality in morphology of sperms.
High end microscopes like the Phase Contrast Microscope make study of morphology easier and more predictable. Due to its high cost, not all labs have phase contrast microscopes and usually their availability is restricted to Infertility units and their Laboratories. This is the reason why sperm test or semen analysis test is more expensive at Infertility Units.
Insufficient magnification and contrast provides little data about the morphology of sperms, making the Semen Analysis done at regular Pathology services of little use when it comes to diagnosing infertility.
What is Advanced Semen Analysis?
Overview
Advanced Semen Analysis includes study of Morphology and Vitality of sperms in the semen sample apart from the Concentration and Motility assessment. Since we use a high end Phase Contrast Microscope to analyse the semen sample, it leads to a more reliable and accurate assessment of all factors that can affect fertility.
As shown below, Phase Contrast Microscope gives much better visualization of Sperms making their assessment accurate.
Commonly Asked Semen Analysis Questions
Find answers to common questions about semen analysis, sample collection, preparation, sperm parameters and understanding test results.
Semen analysis is a laboratory test used to evaluate semen and sperm characteristics. It commonly assesses semen volume, sperm concentration, sperm motility and sperm morphology.
Semen analysis is commonly performed as part of a male fertility evaluation. It provides information about sperm production and important sperm characteristics.
Depending on the laboratory and test requested, semen analysis may evaluate semen volume, sperm concentration, sperm motility, sperm morphology and, when indicated, sperm vitality or other parameters.
A semen sample is generally collected according to the instructions provided by the fertility clinic or laboratory. The laboratory will explain the appropriate collection procedure before testing.
The recommended period of sexual abstinence can vary according to laboratory instructions. Follow the specific instructions provided by your fertility specialist or testing laboratory.
Some laboratories allow home collection if their specific requirements are followed. Ask the laboratory about its collection, transportation and timing instructions before collecting the sample at home.
Sperm concentration refers to the number of sperm present in a specific volume of semen. It is one of the important parameters assessed during semen analysis.
Sperm motility refers to sperm movement. The laboratory evaluates how many sperm are moving and may classify their movement according to laboratory standards.
Sperm morphology refers to the size and shape of sperm cells. It is evaluated as one part of the semen analysis.
Sperm vitality indicates the proportion of sperm that are alive in the semen sample. It may be assessed when clinically indicated.
Not necessarily. Semen parameters can vary, and an individual abnormal result does not by itself determine the complete fertility status of a man or couple. The results should be interpreted by a fertility specialist in the appropriate clinical context.
Yes. Semen parameters may vary between samples. Depending on the result and clinical situation, a fertility specialist may recommend repeating the analysis.
The time required depends on the laboratory and the tests included. Basic semen analysis can generally be processed within a relatively short period, while specialized testing may require additional time.
If semen parameters are outside the expected range, the fertility specialist may review your medical history and examination and may recommend repeat semen analysis or additional hormonal, imaging, genetic or specialized investigations.
Yes. Semen analysis is commonly used during the evaluation of male fertility and may be performed before selecting an appropriate fertility treatment.
