Infertility is becoming an increasingly prevalent issue globally, affecting approximately one in every six couples of reproductive age, according to the World Health Organization (WHO). In Spain, data from the Spanish Society of Fertility (SEF) suggests that infertility impacts 15-20% of couples. Defined as the inability of an individual to conceive naturally, infertility is recognized as a medical condition by the WHO, capable of affecting both male and female reproductive systems. Diagnosis typically requires a couple to engage in regular unprotected sexual intercourse for 12 months without achieving pregnancy, although for women over 35, this period is shortened to six months.

The Expert Perspective

Antonia González, an embryologist specializing in fertility treatments, observes a rising trend in infertility cases, leading to the proliferation of fertility clinics. She attributes this increase to various factors, with age at first pregnancy and lifestyle being primary contributors. Couples are delaying parenthood, especially women, whose fertility is constrained by biological clocks, particularly after the age of 35. Lifestyle habits also play a crucial role, as exposure to toxins can disrupt hormonal and immune systems necessary for viable pregnancies. Conditions such as endometriosis and polycystic ovary syndrome (PCOS) have seen an uptick, potentially due to increased exposure to environmental toxins.

Lifestyle Factors and Infertility

Sedentary lifestyles are another contributing factor to rising infertility rates, according to González. Lack of exercise or prolonged sitting can adversely affect glucose and insulin levels, impacting metabolism. Nutritional deficiencies are prevalent among patients, exacerbated by poor dietary habits and compromised digestive health. Disrupted circadian rhythms, influenced by irregular eating and sleeping patterns, further compound fertility issues, as optimal reproductive function requires a balance between the immune, hormonal, and nervous systems.

Nutritional Approaches to Addressing Infertility

Beatriz Méndez del Río, a nutritional therapist and health coach specializing in functional fertility and hormonal health, emphasizes the importance of nutrition in addressing infertility. Women presenting with various conditions affecting fertility often exhibit nutritional deficiencies and hormonal imbalances, necessitating a comprehensive assessment of their medical and personal histories. Understanding factors such as birth method, breastfeeding, and familial fertility issues provides valuable insights into individual fertility challenges.

Tailored Nutrition Plans

Méndez del Río employs personalized nutrition plans based on detailed dietary assessments spanning seven to ten days. These plans not only consider food choices but also meal timing, portion sizes, and associated symptoms throughout the day. The goal is to optimize nutrient intake, stabilize blood sugar levels, and support overall health and fertility. While there’s no one-size-fits-all approach, emphasizing nutrient-dense foods, adequate caloric and macronutrient intake, and stable blood sugar levels forms the foundation of her nutritional strategies.

Impact of Lifestyle Habits

Echoing González’s observations, Méndez del Río underscores the role of lifestyle habits such as sedentary behavior, poor diet, excessive consumption of sugars and trans fats, tobacco, alcohol, and marijuana in compromising reproductive health. While exercise is beneficial, excessive physical activity can negatively impact fertility. Sleep quality also emerges as a critical factor, with inadequate rest disrupting various physiological processes essential for fertility. Furthermore, stress management is paramount, as chronic stress can significantly affect reproductive health.


Infertility presents a multifaceted challenge influenced by age, lifestyle, and environmental factors. Addressing this issue requires a comprehensive approach encompassing medical interventions, nutritional strategies, and lifestyle modifications. By understanding the underlying causes and implementing targeted interventions, individuals and couples grappling with infertility can optimize their chances of conception and achieve their dream of parenthood.

With infertility rates on the rise, the collaboration between medical professionals, nutritionists, and lifestyle coaches becomes increasingly vital in providing holistic support to those navigating the complex journey of fertility. Through education, awareness, and proactive intervention, we can work towards mitigating the impact of infertility and empowering individuals to build the families they desire.

This comprehensive approach not only addresses immediate fertility concerns but also promotes overall health and well-being, laying the foundation for a healthier, more fertile future for generations to come.
