Explore why female infertility is on the rise, key causes, risk factors, prevention tips, and treatment options for women’s reproductive health.
Infertility is no longer an uncommon challenge. In recent years, the number of women experiencing difficulties conceiving has steadily increased across the globe. While technological advancements have made treatments like IVF more accessible, understanding the root causes of infertility—also referred to as barrenness—is vital for prevention and intervention.
What Is Female Infertility?
Female infertility refers to a woman’s inability to get pregnant after a year of regular, unprotected sex. In women over 35, this window shortens to six months. It can be due to problems with ovulation, fallopian tubes, uterus, or other hormonal and lifestyle factors.
Common Causes of Infertility in Women
1. Ovulation Disorders
The majority of infertility cases in women are linked to ovulation disorders. These include conditions like:
- Polycystic Ovary Syndrome (PCOS): A hormonal imbalance that interferes with the regular release of eggs.
- Hypothalamic Dysfunction: Stress, excessive exercise, or sudden weight changes can affect the part of the brain that controls ovulation.
- Premature Ovarian Insufficiency: When ovaries stop functioning before age 40 due to genetics or autoimmune conditions.
- Hyperprolactinemia: Elevated prolactin levels can disrupt ovulation and cause irregular periods.
2. Fallopian Tube Damage or Blockage
Fallopian tubes are responsible for transporting the egg from the ovary to the uterus. Any damage can prevent fertilisation. Common causes include:
- Pelvic inflammatory disease (PID)
- Sexually transmitted infections like chlamydia and gonorrhoea
- Previous surgeries or ectopic pregnancies
3. Endometriosis
This is a painful disorder where uterine-like tissue grows outside the uterus. It can damage the ovaries, block fallopian tubes, and create inflammation, making conception difficult.
4. Uterine and Cervical Abnormalities
These include:
- Uterine polyps or fibroids: Can obstruct implantation.
- Abnormally shaped uterus: Can interfere with fertilisation or increase miscarriage risk.
- Cervical stenosis: Narrowing of the cervix can hinder sperm passage.
5. Unexplained Infertility
In nearly 10–20% of infertility cases, no exact cause is found. These might involve subtle abnormalities in eggs, sperm, or reproductive functioning that current technology cannot yet detect.
Rising Risk Factors for Infertility
1. Delaying Parenthood
One major modern factor is delayed childbearing. Women are increasingly choosing to start families later in life due to education, career goals, or financial planning. However, fertility begins to decline significantly after 35.
2. Lifestyle and Environmental Factors
- Smoking and alcohol: These substances harm reproductive organs and hormone balance.
- Poor diet and obesity: Excess weight can affect ovulation and insulin resistance, especially in PCOS cases.
- Environmental toxins: Exposure to pesticides, plastics (like BPA), and radiation can impact fertility.
- Chronic stress: High stress hormones can suppress reproductive hormone activity.
3. Medical Conditions
Autoimmune disorders, thyroid imbalances, diabetes, or even undiagnosed infections can impair fertility. Regular medical screenings are essential.
When Should You Seek Medical Advice?
If you're under 35 and haven’t conceived after a year of trying, or over 35 and haven’t conceived after six months, it’s time to speak to a gynaecologist or fertility specialist. Early testing can help determine the best path forward.
Diagnosis of Infertility
A fertility assessment may include:
- Blood hormone tests
- Pelvic ultrasound
- Ovulation tracking
- Hysterosalpingography (X-ray of uterus and fallopian tubes)
- Partner's semen analysis
Fertility Treatment Options
1. Medication
Drugs like Clomiphene citrate and Letrozole help stimulate ovulation. These are often used in early stages.
2. Assisted Reproductive Technologies (ART)
- Intrauterine insemination (IUI): Washed sperm is inserted directly into the uterus.
- In-vitro fertilisation (IVF): Eggs are fertilised outside the body and then transferred into the uterus.
- Intracytoplasmic sperm injection (ICSI): A single sperm is injected into an egg, often used in male infertility cases.
3. Surgery
In cases of fibroids, endometriosis, or blocked fallopian tubes, surgery may be necessary to restore normal anatomy.
Can Infertility Be Prevented?
While not all causes are preventable, here are ways to protect your fertility:
- Maintain a healthy weight and exercise regularly
- Avoid smoking, alcohol, and recreational drugs
- Use protection against STIs
- Manage chronic conditions like diabetes or thyroid issues
- Get regular gynaecological check-ups
Emotional Impact of Infertility
Struggling with infertility can be emotionally draining and may lead to anxiety, depression, or relationship stress. Seeking mental health support through counselling or fertility support groups is highly recommended.
Women’s Fertility Awareness: A Public Health Priority
Governments and healthcare organisations should prioritise reproductive education, preventive care, and destigmatisation of infertility. Early intervention and awareness can significantly reduce complications and empower women in their reproductive journey.
