Myth or reality: Does diet influence fertility?
By Dr. Vega Cabezuelo – Gynecologist at the Women's Unit, Ruber International Hospital
We often hear the saying "we are what we eat," but can our diet really affect our fertility? The answer is clear. yes.
According to Dr. Vega Cabezuelo, gynecologist at the Women's Unit of the Ruber International Hospital, both our dietary habits and certain external agents present in our environment can directly impact our reproductive capacity.
Diet and fertility: a direct relationship
An unbalanced diet, tobacco, alcohol, or drug use not only affect our overall health but also negatively impact fertility in both men and women. One of the key factors is being overweight or obese, which contributes to increased cellular toxicity and oxidative stress.
In the case of man, excess weight can reduce testosterone levels, alter semen quality and promote erectile dysfunction. For its part, Woman Obese women may experience ovulatory irregularities, a decreased response to hormonal treatments, and oocytes with more genetic alterations. All of this can translate into embryos with chromosomal abnormalities, a lower implantation rate, and a higher risk of miscarriage.
Furthermore, we must not forget that an inadequate diet can also alter the intestinal and endometrial microbiota, two key elements in the embryo implantation process.
External agents: beyond what we eat
But not everything depends on what we choose to eat. There are substances present in the environment, food, water, or even cosmetics that can accumulate in our bodies and affect our reproductive health. Many of these compounds lipophilic, remain in our body for years and can even be transmitted between generations by epigenetic mechanisms.
Some of the most relevant ones are:
- Endocrine disruptors: interfere with normal hormonal function.
- Organochlorines (such as DDT): present in contaminated water and some fish.
- Organophosphates: used in pesticides, could be found in fruits and vegetables.
- Phthalates: used in the manufacture of plastics such as PVC.
- Bisphenol A: present in many plastic containers and linked to adverse effects on reproductive health.
Fertility is not an issue isolated from the rest of our health. Taking care of our diet, maintaining a healthy weight, and reducing exposure to toxic substances are fundamental steps to protecting our reproductive health. At the Women's Unit, we believe in prevention and the power of information to make informed decisions.
