Fertility Test for Men

Introduction

The male fertility process is a complex process and depends on healthy sperm production and the ability of sperm to fertilise an egg. The sperm needs to be mature, healthy, and able to swim through the female reproductive tract effectively to fertilise an egg successfully. Timely evaluation through male infertility tests can support early diagnosis and identification of issues, and help to get appropriate medical treatment and make lifestyle modifications to improve chances of conception.

What Fertility Test Is Used to Diagnose Male Infertility?

Male fertility testing assesses sperm viability. The semen analysis is the main test to assess whether a man's sperm can fertilise an egg. The semen analysis is often the first test a doctor will recommend for a couple who have been trying to conceive for over one year and have not achieved natural conception. The test helps determine the physical characteristics of sperm, such as their number, speed, and structure. It aims to evaluate the health of the man's sperm without relying on self-reported information.

Guidelines to Prepare for a Semen Test

Doctors guide patients in preparing for a semen test to ensure accurate results. This includes the following:

• Avoid alcohol, smoking, and caffeine intake
• Tell your doctor if you are taking any medications
• Avoid taking hot baths and saunas
• Avoid sexual activity for up to 72 hours

Understanding the Results of Semen Analysis

The results of semen analysis are compared with the standard reference ranges, which are the following:

• A normal sperm count includes 15 million sperm per millilitre or more
• At least 40 per cent motile sperm is considered normal
• Normal morphology refers to the presence of at least 4 per cent properly shaped sperm.
• Abnormal results do not mean infertility in all cases, but further evaluation is indicated.

What Other Fertility Tests Are Used for Men?

When there are abnormal findings from a semen analysis, the doctor may recommend other fertility tests for men to to identify causes of difficulty in achieving conception.

Blood tests may be done to determine hormone levels (testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH)), as these hormones regulate sperm production and male reproductive function.

Genetic testing may be conducted to identify inherited diseases, chromosomal abnormalities, or other reasons that could impact the ability to conceive.

An ultrasound of the scrotum is a typical, non-invasive imaging procedure that evaluates the anatomy of both testicles and the surrounding structures. An ultrasound can assist in the evaluation of conditions such as varicocele and blockages that may affect sperm production and transport, as well as abnormalities that impede normal sperm function.

Another advanced method evaluates sperm (sperm DNA fragmentation) to determine damage to the sperm DNA. High levels of DNA damage can significantly reduce the likelihood of successful fertilisation and can contribute to recurrent pregnancy loss.

The combination of these advanced diagnostic tests enhances understanding of male infertility and facilitates implementation of appropriate medical therapy.

Conclusion

Male fertility testing is an important process for determining male reproductive health. Semen analysis is still the best and most frequently used method for diagnosing male infertility and provides detailed information about the quality and function of sperm. Most men should undergo at least one sperm count test; therefore, getting tested early may help men identify potential problems that affect their ability to have children and allow the couple to seek treatments that will help them conceive.
