Understanding Infertility

Infertility is defined as the inability to conceive even after 12 months of regular, unprotected intercourse (or 6 months if the woman is above 35 years). It affects both men and women equally, yet many couples feel confused, anxious, or guilty when pregnancy doesn’t happen naturally.

The good news is most causes of infertility are identifiable and treatable, especially with early diagnosis and expert care.

Common Reasons for Infertility in Women

1. Ovulation Disorders

Irregular or absent ovulation is one of the leading causes of female infertility. Conditions like:

PCOS (Polycystic Ovary Syndrome)

Hormonal imbalance

Thyroid disorders

can prevent eggs from being released regularly.

2. Low Egg Reserve (Low AMH)

As women age, the number and quality of eggs decline. Low AMH levels indicate reduced ovarian reserve, which can affect natural conception and IVF outcomes.

3. Blocked Fallopian Tubes

Blocked or damaged tubes prevent the egg and sperm from meeting. Common causes include:

Pelvic infections

Tuberculosis

Previous surgeries

4. Endometriosis

Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus, affecting egg quality, ovulation, and implantation.

5. Uterine Problems

Fibroids, polyps, or abnormalities in the uterus can interfere with embryo implantation or cause repeated miscarriages.

Common Reasons for Infertility in Men

6. Low Sperm Count

Low sperm concentration reduces the chances of fertilisation. Causes may include:

Hormonal issues

Heat exposure

Lifestyle habits

7. Poor Sperm Motility or Shape

Even if sperm count is normal, poor movement or abnormal shape can prevent sperm from reaching and fertilising the egg.

8. Azoospermia (No Sperm in Semen)

Some men produce little or no sperm due to:

Blockages

Hormonal disorders

Genetic conditions

Advanced fertility treatments can still offer solutions.

9. Lifestyle Factors

Smoking, alcohol consumption, stress, obesity, lack of exercise, and poor sleep can negatively affect both male and female fertility.

Shared Causes Affecting Both Partners

10. Age

Fertility naturally declines with age, especially after 35 in women and 40 in men.

11. Unexplained Infertility

In some cases, all tests appear normal, yet pregnancy does not occur. This is known as unexplained infertility and can often be treated successfully with advanced fertility techniques.
