Semen analysis

Semen analysis, also known as a sperm count test, is a vital aspect of male fertility testing and diagnosis. It measures the quantity and quality of semen and sperm produced by a male, giving vital information on male reproductive potential and helping to identify potential causes of infertility.

Overview

Semen analysis is usually one of the first tests recommended when a couple has difficulty conceiving. The results can provide information about the male's fertility status or suggest possible underlying conditions, such as a blockage in the male reproductive tract or a hormonal imbalance.

Components of a Semen Analysis

Semen analysis assesses several parameters, each providing unique information about the sperm and seminal fluid.

Semen Volume

This measures the total amount of semen produced in one ejaculation. Low volume can suggest problems with the seminal vesicles or prostate.

Sperm Concentration

Also known as sperm count, this assesses the number of sperm per milliliter of semen. A low sperm concentration can contribute to infertility.

Sperm Morphology

This evaluates the shape of the sperm. A high percentage of abnormally shaped sperm can affect the ability of the sperm to fertilize an egg.

Sperm Motility

This measures the ability of the sperm to move effectively towards an egg. Poor motility can limit the sperm's ability to reach and fertilize the egg.

Other Parameters

Other aspects assessed can include the semen's pH level, the presence of white blood cells (indicating infection or inflammation), and the presence of immature sperm.

Preparation and Procedure

Prior to a semen analysis, men are typically instructed to abstain from ejaculation for two to seven days to ensure the most accurate results. The sample is usually collected by masturbation into a sterile container, although alternative methods may be used if necessary.

Interpreting Results

Semen analysis results must be interpreted within the context of the individual's overall health and fertility history. Abnormal results can indicate a variety of issues, from hormonal imbalances to physical blockages, and often require further testing to pinpoint the underlying issue.
