Primary Infertility: Understanding Causes, Diagnosis & Treatment

Bringing a new life into the world is one of the most cherished dreams for many couples. However, for some, this journey can be unexpectedly challenging. Primary infertility is a condition where a couple struggles to achieve pregnancy despite trying for at least 12 months of regular, unprotected intercourse (or six months if the woman is 35 or older).

At Thakral Hospital, we believe in empowering you with clear, evidence-based information and compassionate care to navigate this journey. In this comprehensive guide, we will explain what primary infertility is, its causes, diagnostic methods, treatment options, and how our experts can support you.

What is Primary Infertility?

Primary infertility is defined as the inability to conceive a first pregnancy after a year of regular unprotected sex. It is different from secondary infertility, which refers to difficulty conceiving after previously having a successful pregnancy.

Why is this distinction important?

Primary infertility indicates challenges before any successful conception.
It often involves different diagnostic and treatment considerations compared to secondary infertility.

How Common is Primary Infertility?

Infertility is a global health concern affecting millions of couples. According to the World Health Organization, approximately one in six people will experience infertility at some point in their lives.

In India, changing lifestyles, stress, delayed family planning, and medical conditions have contributed to an increasing prevalence of infertility. Recognizing this growing need, Thakral Hospital offers specialized, evidence-based fertility care tailored to individual needs.

Causes of Primary Infertility

Infertility is a complex condition that may stem from male factors, female factors, both partners, or remain unexplained despite thorough evaluation.

General Statistics

35% of infertility cases involve male factors
35% involve female factors
30% involve both partners or remain unexplained
25% of couples have multiple contributing factors

Causes of Primary Infertility in Males

Male infertility is often linked to problems with sperm production, function, or delivery. Below are the most common causes:

1️. Low Sperm Count

Fewer sperm produced reduces the chance of fertilization.
Causes: hormonal imbalances, testicular trauma, infections.

2️. Poor Sperm Motility

Sperm that cannot swim properly cannot reach the egg.
Contributing factors include inflammation, varicoceles (enlarged veins), and infections.

3️. Abnormal Sperm Shape (Morphology)

Misshapen sperm may be unable to penetrate the egg.

4️. No Sperm Production (Azoospermia)

Can be due to genetic conditions, testicular failure, or blockages.

5️. Testicular Abnormalities

Orchitis, vasculitis, varicoceles.
Genetic disorders like Klinefelter syndrome.

6️. Hormonal Disorders

Low testosterone (hypogonadism), pituitary dysfunction.

7️. Lifestyle and Environmental Factors

Smoking, alcohol, obesity, prolonged stress.
Heat exposure (tight clothing, hot tubs).

8️. Medications and Medical Treatments

Steroids, chemotherapy, radiation.

9️. Sexual Dysfunction

Erectile dysfunction, premature ejaculation, retrograde ejaculation.

10️. Infections and STDs

Can damage sperm ducts (vas deferens), leading to blockages.

Causes of Primary Infertility in Females

Female infertility is often due to structural, hormonal, or genetic factors affecting ovulation, egg quality, or the reproductive tract.

Key Causes:

1. Tubal and Peritoneal Disease (~70% of cases)

Blocked fallopian tubes from infections (e.g., Chlamydia, gonorrhoea).
Pelvic inflammatory disease (PID).
Endometriosis causing scarring.

2. Ovulatory Disorders (~20%)

Polycystic Ovary Syndrome (PCOS).
Hypothalamic or pituitary dysfunction.
Primary ovarian insufficiency (POI).

3. Uterine Abnormalities

Fibroids, polyps, congenital anomalies (septate uterus).

4. Poor Egg Quality

Increases with age, especially after 35.
Genetic or chromosomal abnormalities.

5. Endometriosis

Uterine lining tissue growing outside the uterus damages ovaries and tubes.

6. Autoimmune Conditions

Lupus, celiac disease may interfere with fertility.

7. Lifestyle and Health Factors

Obesity, smoking, alcohol, poor nutrition.
Chronic diseases (diabetes, thyroid issues, kidney/liver disease).

Count, motility, morphology.

Hormonal Tests

Testosterone, FSH, LH, prolactin.

Genetic Testing

For chromosomal or Y-chromosome microdeletions.

Imaging

5. Donor Programs
