Fertility Killers – What Can Harm Your Chances of Becoming a Parent

In a world where many couples dream of becoming parents, it is important to understand that certain everyday factors can seriously affect fertility—both in women and in men. These “fertility killers,” often overlooked, deserve our full attention. Here are the main ones.

1. Chronic Stress

Intense and prolonged stress can disrupt the hormonal axis that regulates ovulation in women and sperm production in men. It can also affect libido, making intercourse less frequent. Stress management is therefore essential in any pregnancy plan.

2. Tobacco and Alcohol

In women, smoking damages the ovarian reserve and accelerates ovarian aging. In men, it reduces sperm quality. Alcohol can disrupt the menstrual cycle and lower testosterone levels. Ideally, both substances should be stopped or significantly reduced.

3. Overweight and Obesity

A high body mass index (BMI) is associated with reduced fertility. In women, it can lead to irregular cycles or absence of ovulation. In men, it can lower sperm concentration and motility.

4. Being Underweight

On the other hand, being underweight can also prevent ovulation. The body, in “survival mode,” puts non-vital functions like reproduction on hold.

5. Age

This is one of the most determining factors. Fertility naturally declines with age—especially after 35 for women and, to a lesser extent, after 40 for men. It is important to take this into account when planning to have children.

6. Endocrine Disruptors

These chemical substances—found in plastics, certain cosmetics, pesticides, and cleaning products—can interfere with reproductive hormones. It’s advisable to choose natural, fragrance-free, and paraben-free products, and to avoid heating food in plastic containers.

7. Excessive Heat (in Men)

Testicles need to stay slightly cooler than body temperature. Frequent hot baths, laptops on the lap, or tight clothing can impair sperm production.

8. Sleep Disorders

Poor sleep can interfere with the secretion of reproductive hormones. Good sleep hygiene supports fertility.

9. Sexually Transmitted Infections (STIs)

If left untreated, certain STIs like chlamydia or gonorrhea can cause damage to the fallopian tubes or male reproductive system, leading to infertility.

10. Certain Medications or Medical Treatments

Some treatments—such as cancer therapies, antidepressants, or anti-inflammatory drugs—can affect fertility. It’s important to inform your doctor about any pregnancy plans.

Conclusion:

Many of these factors are modifiable. Early intervention, a healthy lifestyle, and regular medical check-ups can greatly improve your chances of conceiving. If pregnancy has not occurred after more than 12 months of regular intercourse (or after 6 months if you’re over 35), it’s advisable to consult a fertility specialist.
