Understanding Infertility: Causes and Contributing Factors

Infertility is a growing concern for many couples who are trying to conceive. Medically, it is defined as the inability to achieve pregnancy after 12 months of regular, unprotected intercourse. While it can feel overwhelming, infertility is not uncommon — and most importantly, it is treatable.

At Nex IVF and Fertility Centre, Patna, we believe that awareness is the first step to action. In this blog, we break down the common causes of infertility and the factors that may be affecting your chances of conception.

Understanding Infertility Causes and Contributing Factors Nex IVF Patna

🔍 Causes of Infertility in Women

1. Ovulation Disorders

Irregular or absent ovulation is one of the most common causes of female infertility. Conditions like Polycystic Ovary Syndrome (PCOS), thyroid imbalance, or hormonal disorders can interfere with the monthly release of eggs.

2. Uterine or Cervical Issues

Structural abnormalities such as uterine fibroids, polyps, or cervical stenosis can hinder the implantation of a fertilized egg or block sperm movement.

3. Fallopian Tube Damage or Blockage

Infections like pelvic inflammatory disease (PID) or conditions like endometriosis can damage or block the fallopian tubes, preventing the egg and sperm from meeting.

4. Age and Egg Quality

As women age, both the quantity and quality of eggs naturally decline. After age 35, fertility drops significantly, and the chances of chromosomal abnormalities rise.

🔍 Causes of Infertility in Men

1. Sperm Abnormalities

Low sperm count, poor motility (movement), or abnormal sperm shape can reduce the chances of successful fertilization.

2. Varicocele

This condition involves the swelling of veins within the scrotum and can negatively impact sperm quality and production.

3. Sexual Function Disorders

Erectile dysfunction, premature ejaculation, or blockages in the reproductive tract can all affect male fertility.

4. Lifestyle Habits

Smoking, alcohol, drug use, obesity, and even tight clothing can reduce sperm production and hormonal balance.

🔍 Shared or Combined Factors

1. Medical Conditions

Diseases such as diabetes, thyroid disorders, or autoimmune conditions can disrupt hormonal or reproductive functions in both men and women.

2. Environmental Exposure

Prolonged exposure to chemicals, radiation, or pesticides may affect fertility levels over time.

3. Stress and Mental Health

Chronic stress can influence hormonal balance, ovulation, and sexual function — often without you even realizing it.
