How Balanced Nutrition Improves Reproductive Health in Men and Women - Dr Aaheli Maiti

Conversations around fertility are often dominated by complex terminology, including Anti-Müllerian Hormone, Antral Follicle Count, embryo grading, endometrial receptivity, and more.

What often escapes the microscope is the diet – a silent variable that subtly affects hormones and, consequently, overall reproductive health.

Reproductive health is a chain of finely balanced processes. Hormones must function in rhythm, eggs and sperm must develop with integrity, and the uterus must be ready to sustain life.

None of this happens in isolation from what the body is fed. A poor diet does not show its effects overnight, but over the years, it influences ovulation, sperm quality, and metabolic health in ways that are sometimes only visible when couples begin trying to conceive.

For women, food choices affect both immediate and long-term fertility. Folate and iron are critical for egg development and pregnancy, while vitamin D deficiency is increasingly being recognised as a silent disruptor of cycles.

Omega-3 fatty acids and antioxidants from fresh fruits and vegetables help protect eggs from oxidative stress. On the other hand, diets built around processed foods, refined sugars, and trans fats are linked with conditions like PCOS and irregular ovulation.

What is consumed every day, quietly and consistently, becomes the backdrop against which fertility unfolds.

For men, the story is just as direct. Sperm health is highly sensitive to oxidative stress, and diets lacking in antioxidants often lead to poorer motility and DNA damage.

Zinc and selenium support both testosterone production and sperm function, and when they are deficient, semen parameters decline. Lifestyle habits – alcohol, smoking, excessive red meat, or high-fat diets – worsen the picture.

It is striking how often improvements in diet reflect positively in semen analysis, even without any other intervention.

Weight, too, is part of the conversation. Both extremes – obesity and undernutrition – interfere with hormonal balance. Women with higher body fat may struggle with irregular cycles, while very low body weight can suppress ovulation. In men, obesity lowers testosterone and reduces sperm quality.

What restores balance is not restrictive dieting but a consistent pattern of balanced eating, where energy intake, micronutrients, and metabolic health align to support reproduction.

The larger point is that nutrition is not a side note in fertility care; it is a core element. Food is the most fundamental input the body receives. Medicines and technologies can only work on the foundation that the body provides. Balanced nutrition builds that foundation, shaping not only the possibility of conception but also the health of the next generation.
