Spermatests

Spermatests, also known as semen analysis or sperm count tests, are laboratory examinations of a semen sample. This type of test is primarily used to assess male fertility. It evaluates several parameters of the semen, including the volume of ejaculate, the concentration of sperm (sperm count), the motility of the sperm (how well they move), and the morphology of the sperm (their shape).

The procedure typically involves collecting a semen sample through masturbation after a period of abstinence, usually 2 to 5 days. The sample is then analyzed in a laboratory by trained technicians or scientists. They will examine physical characteristics such as color and viscosity. Microscopic examination is crucial for assessing sperm count per milliliter, the percentage of motile sperm, and the percentage of sperm with normal morphology.

Abnormal results in a spermatest can indicate various issues affecting fertility, such as low sperm count (oligozoospermia), poor sperm movement (asthenozoospermia), or an unusually high number of abnormally shaped sperm (teratozoospermia). Other factors like the presence of white blood cells can also be detected, suggesting infection.

Spermatests are a fundamental tool in the evaluation of male infertility and can also be used to confirm the success of vasectomy. While a single test provides valuable information, it is often recommended to repeat the analysis to ensure accuracy and account for natural variations in sperm production. The interpretation of results should always be done in conjunction with a healthcare professional, who can consider the full clinical context.
