Abnormal Semen Analysis

Abnormal Semen Analysis: What Can It Mean?

Semen analysis is an important test that evaluates sperm concentration, movement and shape, together with other semen characteristics. If one or more semen-analysis results fall outside the reference range, there may be various reasons affecting fertility. However, it is important to remember that sperm production varies considerably from one sample to the next, and an abnormal semen analysis does not necessarily mean that there is a serious male fertility problem. In this article, we will explain what an abnormal semen analysis means, what the common abnormalities are, and what can be done to address them.

Abnormal Semen Analysis: Common Abnormalities

Abnormal Semen Analysis: Common Abnormalities

When semen analysis results show abnormalities, it means that one or more of these measurements fall outside the reference range. Below are some common abnormalities and what they may mean:

1. Oligospermia

• What it is: Oligospermia is the condition in which the sperm concentration is below the lower fifth-percentile reference value of 16 million sperm per mL of semen.
• What it means: Oligospermia can reduce the chances of conception, as fewer sperm are available to fertilize the egg.
• Possible causes: Hormonal disorders, genetic abnormalities, infection/inflammation, varicocele, unhealthy lifestyle (smoking, alcohol, obesity).

2. Asthenospermia

• What it is: Asthenospermia is the condition in which sperm motility is low (less than 32% of sperm have progressive motility).
• What it means: Low motility can prevent sperm from reaching and fertilizing the egg.
• Possible causes include poor nutrition, exposure to toxic substances, infection or inflammation, and varicocele.

3. Teratospermia

• What it is: Teratospermia is the condition in which the percentage of sperm with normal morphology is low (below 4%).
• What it means: Abnormal morphology can affect the sperm’s ability to fertilize the egg.
• Possible causes: Genetic abnormalities, infection/inflammation, exposure to toxic substances, radiation.

4. Azoospermia

• What it is: Azoospermia is the complete absence of sperm in the ejaculate.
• What it means: Azoospermia means there are no sperm available for fertilisation, making natural conception impossible.
• Possible causes: Hormonal disorders, obstructive problems (e.g., blocked sperm ducts), genetic abnormalities, previous surgical procedures.

5. Leukocytospermia

• What it is: Leukocytospermia is the presence of a high number of white blood cells in the semen.
• What it means: Leukocytospermia may indicate infection or inflammation in the reproductive system.
• Possible causes: Infections, inflammatory conditions, autoimmune diseases.

What Can You Do?

If semen analysis shows abnormalities, there are various strategies and treatments that can help improve sperm quality and increase the chances of conception.

1. Lifestyle Changes

• Healthy diet: Consume foods rich in antioxidants, vitamins, and minerals.
• Regular exercise: Regular exercise can improve sperm quality.
• Avoid toxic substances: Avoid smoking, excessive alcohol, and exposure to toxic substances.
• Stress management: Use relaxation techniques, such as yoga and meditation.

2. Medical Treatments

• Medication: Some medications can improve sperm production and quality, although this is often uncertain and requires a significant period of time (3-6 months).
• Surgical intervention: In cases of varicocele or obstructive problems, surgical intervention can help.
• Antibiotics: If an infection is confirmed, targeted antibiotics may be prescribed; their effect on semen quality varies.

3. Assisted Reproduction

• Intrauterine Insemination (IUI): Placing sperm directly into the woman’s uterus can increase the chances of conception, especially in cases of mild sperm disorders.
• In Vitro Fertilisation (IVF): Fertilizing eggs with sperm in the laboratory and transferring the fertilised embryos to the uterus can be an effective solution, especially in more severe sperm disorders.
• Intracytoplasmic Sperm Injection (ICSI): Injecting a single sperm directly into the egg can help in cases of severe male infertility.
