Infertility Explained: Causes, Diagnosis & Support for Couples
Last Updated: 4 February 2026
Introduction
Infertility is a medical condition affecting millions of couples worldwide. Defined as the inability to achieve pregnancy after 12 months of regular, unprotected intercourse, infertility can have multiple causes in both men and women. This guide provides an educational overview of common causes, diagnostic evaluation, lifestyle considerations, and emotional support strategies to help couples understand and navigate fertility challenges.
Common Causes of Infertility
Infertility is multifactorial. It can be categorized as female, male, combined, or unexplained. Evidence-based studies show that identifying underlying factors improves outcomes and guides treatment decisions. [WHO, 2024]
| Category | Examples / Conditions | Notes |
|---|---|---|
| Female Factors | Ovulatory disorders (PCOS, hypothalamic dysfunction), tubal damage, endometriosis | Approximately 30–40% of infertility cases involve female factors |
| Male Factors | Low sperm count, poor motility, abnormal morphology | Approximately 30% of cases are male-related |
| Combined | Both partners have contributing factors | 10–20% of cases |
| Unexplained | No identifiable cause despite evaluation | Up to 15% of cases |
Diagnostic Evaluation of Infertility
Early and thorough evaluation helps identify reversible or treatable factors. Typical assessment steps include:
- Medical History: Menstrual cycles, sexual history, previous pregnancies, chronic illnesses, surgeries.
- Physical Examination: Reproductive system assessment, hormonal evaluation.
- Hormonal Testing: FSH, LH, prolactin, thyroid, AMH, and other fertility-related hormones.
- Imaging: Pelvic ultrasound, hysterosalpingography (HSG), or sonohysterography for female factors.
- Semen Analysis: Evaluation of count, motility, and morphology in male partners.
- Specialist Referral: Reproductive endocrinologist or fertility clinic consultation if indicated.
Lifestyle Factors and Fertility
Evidence shows lifestyle significantly impacts fertility. Consider the following recommendations:
- Maintain healthy body weight (BMI 18.5–24.9)
- Consume a balanced diet rich in vitamins, minerals, and antioxidants
- Avoid tobacco, excessive alcohol, and recreational drugs
- Engage in regular, moderate physical activity
- Manage stress through mindfulness, counseling, or supportive social networks
Emotional and Psychological Support
Infertility can cause significant emotional distress, anxiety, and relationship strain. Supportive strategies include:
- Access to counseling or therapy specializing in reproductive health
- Joining support groups for couples experiencing infertility
- Open communication between partners to share feelings and decisions
- Educational resources to improve understanding of treatment options
