Sperm Quality- A Quick Overview

Sperm quality is the measure of the overall health of the total number of sperm cells present in the ejaculate. It helps to determine their ability to accomplish fertilization and maintain male fertility.

This article will be a brief overview of sperm quality and its relationship with male infertility.

What Does Sperm Quality Entail?

Sperm quality is a broad term and includes all the vital features of sperm cells except their count. These include:

1. Sperm Morphology

Sperm morphology is the shape or structure of sperm. For a pregnancy, your sperm should be free of manufacturing errors and contain a head, tail, and midpiece.

  • The head is like a tadpole with a nucleus and a cap covering it from the top.

Above all, 4% of your sperm should have this accurate alignment of structures. If this percentage is lower, it is called teratozoospermia and translates into low sperm quality.

2. Sperm Motility

Sperm motility represents the ability of sperm to move in a way that reaches fertilization. For a high sperm quality, more than 40% of your sperm cells should have forward progression.

Asthenozoospermia (inadequate motile sperm) dampens this quality and results in male infertility.

3. DNA quality

DNA quality is the “software” of sperm cells. If your sperm are structurally sound and motile but possess damaged DNA, their “hardware” features are useless. After all, fertilization is the fusion of male and female genetic material.

Does Semen Have A Role in Sperm Quality?

Semen is a whitish-grey fluid produced by glands in the male reproductive tract.

As its primary function is the transport of sperm through the male reproductive tract, it does not influence sperm production. However, semen plays a vital role in maintaining integrity, because:

· Semen has fructose, which acts as a fuel for sperm motility.

· Semen contains nutrients like zinc that protect DNA from fragmentation.

· Abnormal semen might contain antibodies that attack sperm cells and destroy their morphology.

Semen quality can be judged by its texture, color, and volume.

  1. Texture: The texture should be slightly thicker and not dry up too quickly. Sometimes due to lesser intervals between subsequent ejaculations, semen can become thin or liquidy. If the interval is appropriate, a thin semen consistency is due to a lack of nutrients.
