Low Sperm Count (Oligospermia)

What is Low Sperm Count (Oligospermia)?

Low sperm count, or oligospermia, is a condition where the number of sperm in a man’s semen is below the normal range. Sperm are the male reproductive cells that fertilize a woman’s egg during conception. A low sperm count can make it harder to conceive, but it does not always mean infertility.

Normal Sperm Count

According to the World Health Organization (WHO), a normal sperm count is 15 million sperm per milliliter (ml) of semen or more.

• Mild Oligospermia: 10–15 million sperm/ml
• Moderate Oligospermia: 5–10 million sperm/ml
• Severe Oligospermia: Less than 5 million sperm/ml

Having a low sperm count doesn’t mean that the sperm are of poor quality—although this can sometimes be the case. Both the number of sperm and their ability to move effectively (motility) play crucial roles in conception.

Types of Low Sperm Count 

Oligospermia is classified into two main types based on its cause:

1. Primary Oligospermia: This is due to problems directly in the testes, such as genetic or structural issues.
2. Secondary Oligospermia: This occurs due to external factors like hormonal imbalances, lifestyle habits, or illnesses that interfere with sperm production.

What Are the Risk Factors?

Many factors can contribute to a low sperm count. Some of these are linked to your health, while others are influenced by your lifestyle or environment. Common risk factors include:

• Hormonal Problems: Disorders involving testosterone and other reproductive hormones can reduce sperm production.
   
• Testicular Problems: Injury, infection, or structural abnormalities affecting the testes can lead to low sperm count.
   
• Genetic Conditions: Klinefelter syndrome or other chromosomal abnormalities may impact sperm production.
   
• Varicocele: Enlarged veins in the scrotum can interfere with blood flow to the testes, affecting their function.
   
• Lifestyle Choices: Smoking, heavy alcohol consumption, and recreational drug use can lower sperm count.
   
• Excessive Heat Exposure: Frequent use of hot tubs, saunas, or sitting for long periods can raise scrotal temperature, impacting sperm production.
   
• Obesity: Being overweight or obese affects hormone levels, which in turn may reduce sperm count.
   
• Medications: Some drugs for cancer, infections, or depression can temporarily or permanently affect sperm quality.
   
• Environmental Toxins: Prolonged exposure to pesticides, industrial chemicals, heavy metals, or radiation can harm sperm production.

Knowing these risks can help you take steps to reduce their impact.

Signs and Symptoms of Low Sperm Count

Low sperm count often goes unnoticed until a couple struggles with infertility. However, there are some signs and symptoms that might indicate an issue:

• Difficulty conceiving a child despite regular, unprotected intercourse
• Thinner or low semen volume during ejaculation
• Hormonal symptoms like low sex drive, reduced body hair, or breast development in men (gynecomastia)
• Testicular swelling, discomfort, or pain
• Erectile dysfunction or trouble achieving/maintaining an erection

Since these symptoms overlap with other conditions, speaking to a specialist is the best way to determine whether you have oligospermia.

How Is Oligospermia Diagnosed?

At Mamata Fertility Hospital, we use advanced diagnostic tools to identify and evaluate low sperm count. A thorough evaluation helps us create the most effective treatment plan for you.

1. Medical History and Physical Examination

Your doctor may ask about your general health, medical history, lifestyle habits, and any ongoing medications. A physical exam will check for conditions like varicocele or abnormalities in the testes or scrotum.

2. Semen Analysis

A semen sample will be analyzed in a laboratory to measure sperm count, motility, and morphology (shape). This test may need to be repeated at least twice to confirm results, as sperm count can vary with time and health.

3. Hormonal Testing

Blood tests are done to check levels of hormones such as testosterone, FSH (follicle-stimulating hormone), and LH (luteinizing hormone). Imbalances could indicate issues with sperm production.

4. Scrotal Ultrasound

This imaging test provides a detailed look at the testes and surrounding structures. It can help detect issues like varicocele or blockages.

5. Genetic Testing

If no clear cause is found, genetic testing may be suggested. Chromosomal abnormalities or gene mutations can sometimes contribute to oligospermia.

6. Special Tests (If Necessary)

Additional tests to assess sperm DNA integrity or biochemical markers may be done for complex cases.

Treatment Options for Low Sperm Count

With the right treatment, many men with oligospermia can improve their chances of fathering a child. Treatment will depend on the underlying cause and severity of the condition.

1. Lifestyle Changes and Supplements

• Quitting smoking, reducing alcohol intake, and avoiding drugs can boost sperm health.
• Regular exercise and a balanced diet rich in antioxidants (e.g., Vitamins C and E, zinc, and folic acid) can improve sperm quality.
• Reducing stress and addressing weight issues can positively impact hormone levels.

2. Medications and Hormone Therapy

If hormonal imbalances are causing low sperm count, medications such as gonadotropins or clomiphene citrate can help regulate and boost sperm production. Treating infections with antibiotics may also resolve related fertility issues.

3. Surgical Treatments

• Varicocele Repair: Surgery can correct varicocele, improving testicular blood flow and sperm production.
• Epididymal or Vas Deferens Blockage Removal: Any blockages preventing sperm from traveling during ejaculation can be surgically treated.

4. Assisted Reproductive Technology (ART)

When natural conception seems difficult, ART options bring hope:

• IVF (In Vitro Fertilization): Combining eggs and sperm in a lab to achieve fertilization, followed by implantation into the uterus.
• ICSI (Intracytoplasmic Sperm Injection): A single healthy sperm is injected directly into an egg. This is ideal when sperm count is very low.

5. Sperm Donation or Adoption

For men whose low sperm count cannot be treated, using donor sperm or exploring adoption may be fulfilling alternatives.

Every patient’s needs are unique, and an individualized approach is key to successful outcomes.
