Low Sperm Count: Understanding Causes and Modern Solutions

Infertility is often perceived as a female-centric issue, but nearly 50% of cases involve male factor challenges. Understanding your sperm health—specifically the count, volume, and vitality—is the first step toward building your family.

1. What is Low Sperm Count (Oligospermia)?

A low sperm count (Oligospermia) is diagnosed when a man has fewer than 15 million sperm per milliliter of semen. While a lower count reduces the statistical probability of natural conception, it does not mean pregnancy is impossible. Many men with oligospermia successfully father children with minimal intervention or assisted techniques.

2. Diagnosed with Zero Sperm (Azoospermia)?

Azoospermia is the complete absence of sperm in the ejaculate. It affects about 1% of all men and up to 20% of men facing infertility. However, many men with azoospermia still produce sperm within the testes; it simply doesn’t reach the ejaculate due to an obstruction or production issues.

Surgical Retrieval Options:

If sperm production is happening, we can bypass the blockage using advanced surgical extraction:

• TESA: Testicular Sperm Aspiration
• PESA: Percutaneous Epididymal Sperm Aspiration
• TESE/Micro-TESE: Direct testicular tissue extraction for better yields.

3. The Significance of Semen Volume

A normal ejaculate volume is usually above 1.5 ml. If you have a consistently low semen volume, it may suggest:

• Blockage or abnormality in the seminal vesicles.
• Ejaculatory duct obstruction.
• Retrograde Ejaculation: Where semen enters the bladder instead of leaving the penis.

4. Are the Sperm Alive? (Sperm Vitality)

Sometimes, the count is normal, but the sperm are immotile. This requires a Sperm Vitality Test to distinguish between “dead” sperm and “live but non-moving” sperm (Necrozoospermia). We use two primary methods:

Don’t Be Confused About the Future

Technological advancements in andrology mean that even “zero count” doesn’t mean “zero hope.” Every case of male infertility has a pathway—be it medication, lifestyle changes, or ICSI with surgically retrieved sperm.
