According to the 2023 National Health Survey, 16% of adults in Spain are obese, with childhood obesity affecting 10% of the population. Additionally, 39% of adults in Spain are overweight. Combined, more than half of the adult population in Spain struggles with excess weight.
This poses a general health risk but also significantly impacts reproductive health. According to the Spanish Fertility Society (SEF), being overweight affects fertility in both men and women.
For women, it is estimated that for each unit increase in Body Mass Index (BMI) above the ideal range, the likelihood of spontaneous pregnancy decreases by 5% per year. Additionally, a higher BMI negatively impacts fertility by worsening various reproductive and metabolic aspects.
For example, women with obesity are at a higher risk of developing polycystic ovary syndrome (PCOS), a condition that can disrupt ovulation and lead to infertility.
Obesity can also cause menstrual irregularities and reduce the effectiveness of fertility treatments such as in vitro fertilization (IVF). Furthermore, excess weight is linked to an increased risk of miscarriage.
In men, obesity is associated with reduced sperm quality and a higher likelihood of infertility.
Being overweight can disrupt hormonal balance, affecting sperm production, and may even lead to erectile dysfunction, making conception more challenging.
In general, adopting a balanced diet rich in healthy foods can significantly enhance fertility. Fruits and vegetables are packed with antioxidants, with berries like blueberries and raspberries being particularly beneficial.
It’s also crucial to include healthy fats from sources like avocados, nuts, seeds, and olive oil, as well as high-quality proteins found in lean meat, fish, eggs, and legumes. These foods are essential for hormonal production and ovarian follicle growth.
