Infertility

Infertility is defined as the inability to conceive after 12 months of regular, unprotected intercourse for women under 35, or after six months for women over 35. It can also refer to the inability to carry a pregnancy to term.

Types of Infertility

  1. Primary Infertility:
    Difficulty in conceiving a child for the first time.

  2. Secondary Infertility:
    Difficulty in conceiving after having previously given birth to a child.

Causes of Infertility

In Women

  1. Ovulation Disorders:

    • Polycystic Ovary Syndrome (PCOS).
    • Premature ovarian insufficiency.
    • Hormonal imbalances affecting ovulation (e.g., thyroid disorders).

  2. Uterine or Tubal Problems:

    • Blocked or damaged fallopian tubes.
    • Uterine fibroids or polyps.
    • Endometriosis.

  3. Cervical Issues:

    • Abnormal cervical mucus that prevents sperm from reaching the egg.

  4. Age-Related Decline:

    • Decreased ovarian reserve and egg quality with age.

  5. Lifestyle Factors:

    • Obesity, smoking, excessive alcohol consumption, or stress.

In Men

  1. Low Sperm Quality or Quantity:

    • Low sperm count or poor motility.

  2. Structural or Functional Problems:

    • Varicocele (enlarged veins in the scrotum).
    • Blockages in the reproductive tract.

  3. Hormonal Imbalances:

    • Low testosterone levels.

  4. Genetic Factors:

    • Chromosomal abnormalities or genetic conditions like Klinefelter syndrome.

  5. Lifestyle Factors:

    • Excessive alcohol, smoking, drug use, or exposure to toxins.

Diagnosis of Infertility

  1. In Women:

    • Ovulation Tracking: Monitoring ovulation patterns with basal body temperature or ovulation predictor kits.
    • Blood Tests: Hormonal tests for FSH, LH, AMH, or thyroid function.
    • Imaging Tests: Ultrasound, hysterosalpingography (HSG), or laparoscopy to evaluate reproductive organs.

  2. In Men:

    • Semen Analysis: Assessing sperm count, motility, and morphology.
    • Blood Tests: Checking testosterone and other hormone levels.
    • Imaging Tests: Ultrasound of the scrotum to detect abnormalities.

Treatment Options

Lifestyle Changes:

  • Maintain a healthy weight.
  • Quit smoking and limit alcohol consumption.
  • Reduce stress through mindfulness or therapy.

Medications:

  1. For Women:

    • Clomiphene Citrate: Stimulates ovulation.
    • Letrozole: Often used for women with PCOS.
    • Gonadotropins: Hormonal injections to promote egg production.

  2. For Men:

    • Hormonal therapy for low testosterone.
    • Medications to treat infections or other underlying conditions.

Assisted Reproductive Techniques (ART):

  1. Intrauterine Insemination (IUI):

    • Sperm is directly placed into the uterus during ovulation.

  2. In Vitro Fertilization (IVF):

    • Eggs are fertilized outside the body, and the embryo is implanted into the uterus.

  3. Intracytoplasmic Sperm Injection (ICSI):

    • A single sperm is injected into an egg to assist fertilization.

  4. Egg or Sperm Donation:

    • Using donor eggs or sperm if quality issues are present.

  5. Surrogacy:

    • Another woman carries the pregnancy for the intended parents.

Emotional and Psychological Impact

Infertility can cause significant stress, anxiety, or depression. Counseling or support groups can provide emotional relief and coping strategies.

Prevention of Infertility

  1. Maintain a healthy lifestyle.
  2. Avoid STIs by practicing safe sex.
  3. Limit exposure to environmental toxins.
  4. Seek early treatment for underlying medical conditions.
