Why Am I Not Getting Pregnant? Key Factors That Affect Fertility
For many couples, the dream of becoming parents turns into a frustrating journey when pregnancy doesn’t arrive. While it’s natural to expect quick results, only about one third of fertile couples conceive within the first month of trying. At Clínica Fertia, we provide expert support in assisted reproduction to help you identify possible causes and find the right path to parenthood.

When should I consult a fertility specialist?
- Under 35: Seek help if pregnancy hasn’t occurred after 12 months of regular unprotected intercourse.
- Ages 35–39: Consult a specialist after 6 months of trying without success.
- 40 and over: It is advisable to consult immediately.
Main factors affecting fertility
Age
Fertility decreases significantly with age, especially after 35. The number and quality of eggs decline, increasing the risk of miscarriage and reducing the chances of natural conception.
Smoking
Smoking harms ovarian reserve and damages sperm DNA, reducing embryo quality and increasing miscarriage risk.
Alcohol
Alcohol consumption can impair both female and male fertility.
Body weight
Both overweight and underweight conditions can disrupt ovulation. Obesity in women and men affects hormonal balance and reproductive health.
Sexually transmitted infections (STIs)
Infections like chlamydia or gonorrhoea may damage the fallopian tubes, impacting fertility.
Endometriosis
This condition affects around 35% of women with infertility. It can damage ovarian function, alter reproductive anatomy, and interfere with embryo implantation.
Polycystic Ovary Syndrome (PCOS)
PCOS is a hormonal disorder that often causes irregular ovulation and metabolic changes that reduce fertility.
How can I improve my fertility?
- Maintain a healthy weight: Regular moderate exercise supports ovulation. Avoid extreme physical activity.
- Quit smoking and alcohol: These habits negatively affect fertility and fetal development.
- Reduce stress: Chronic stress may reduce treatment success. Prioritise rest, exercise, and a balanced diet.
- Adopt a healthy diet: Avoid trans fats and processed foods. Choose vegetables, fruits, legumes, oily fish, and folic acid-rich foods.
