Male Infertility

What is it?

Male infertility is a condition in which pregnancy is difficult to achieve due to male-related factors. Generally, if a couple is unable to conceive after one year of regular unprotected intercourse, medical evaluation is recommended. Approximately 40–50% of infertility cases involve male-related factors.

Possible Causes

1. Sperm Production Problems

• Low sperm count
• Reduced sperm motility
• Abnormal sperm structure (morphology)

2. Varicocele

• Enlargement of the veins in the testicles
• One of the most common causes of male infertility

3. Hormonal Problems

• Imbalance of testosterone or other hormones

4. Infections

• Genital infections
• Prostate or epididymis infections

5. Lifestyle Factors

• Smoking
• Alcohol consumption
• Obesity
• Excessive heat exposure
• Certain medications

Main Symptoms

In many cases, there may be no obvious symptoms. However, some men may experience:

• Pain or swelling in the testicles
• Sexual problems
• Symptoms related to hormonal imbalance

Diagnosis

Evaluation of male infertility may include several tests.

1. Semen Analysis

The most important test. It evaluates:

• Sperm count
• Sperm motility
• Sperm morphology

2. Hormone Tests

• Testosterone
• FSH
• LH
• Prolactin

3. Imaging

• Ultrasound scrotum
• Doppler study (for varicocele)

4. Genetic Tests

In some severe cases:

• Karyotype analysis
• Y chromosome microdeletion test

Treatment

Treatment depends on the underlying cause.

1. Lifestyle Improvement
