What is Primary Infertility?

Primary infertility refers to the inability to conceive or carry a pregnancy after one year of regular unprotected intercourse, in couples who have never achieved pregnancy before. It differs from secondary infertility, where a couple has previously conceived but is unable to do so again.

Causes of Primary Infertility

Female Factors

• Ovulation disorders: Conditions like polycystic ovarian syndrome (PCOS) or thyroid dysfunction can disrupt egg release.
• Tubal damage or blockage: Often due to pelvic infections, endometriosis, or past surgeries.
• Uterine abnormalities: Fibroids, adhesions, or congenital malformations can affect implantation.
• Age-related decline: Egg quality decreases significantly after age 35.

Male Factors

• Low sperm count or motility: Can reduce chances of fertilization.
• Hormonal imbalances: Affect sperm production and quality.
• Genetic or structural issues: Blockages or testicular dysfunction can contribute.

Combined or Unexplained Causes

In some cases, both partners contribute to infertility, or no clear cause is found despite thorough evaluation (unexplained infertility).

Diagnosis and Evaluation

Accurate diagnosis is crucial for effective treatment. A fertility specialist may recommend:

• Medical history & physical exam: Reviewing menstrual patterns, lifestyle, and health conditions.
• Hormone testing: To assess ovulation, thyroid function, and reproductive hormones.
• Ultrasound or hysterosalpingography (HSG): To check uterus and fallopian tubes.
• Semen analysis: Evaluating sperm count, motility, and morphology.

Treatment Options

Treatment depends on the underlying cause and may include:

• Lifestyle modifications: Maintaining healthy weight, balanced diet, reducing stress, and avoiding smoking/alcohol.
• Medications: Fertility drugs like clomiphene or letrozole to stimulate ovulation.
• Surgical options: Removing fibroids, repairing blocked tubes, or correcting structural issues.
• Assisted Reproductive Technologies (ART): Options like intrauterine insemination (IUI) or in vitro fertilization (IVF) provide advanced solutions.
