However, nutrition and other lifestyle decisions on fertility should not be underestimated. Whether used in conjunction with fertility therapy or on their own, changes in food can have a substantial and measurable impact on fertility.

Bodyweight is perhaps the most crucial thing to consider.

The well-known relationship between fertility and weight
Patients, both male and female, should be aware that being underweight or obese can significantly impact their fertility. The male and female reproductive systems rely on a precise hormonal balance to function effectively. When these systems are stressed due to low or high body weight, their normal chemical cycles break down.

Obese or underweight women, in particular, have been demonstrated to have a greater prevalence of infertility and a lower likelihood of IVF pregnancy. Obesity has been shown to negatively influence male fertility in terms of sperm count and motility (the rate at which sperm move).

Furthermore, obesity has been associated with the onset and progression of polycystic ovarian syndrome (PCOS), a major cause of infertility in women with irregular periods and inconsistent ovulation. When an overweight woman with PCOS reduces just 10% to 15% of her body weight, her symptoms, including infertility, can be decreased.

To Deal with PCOS, Change Your Lifestyle

How can you tell whether your weight has an impact on your fertility? Take a look at your BMI to get a decent idea of where to start (BMI). While BMI does not consider critical aspects like muscle mass and body fat percentage, it can help patients determine whether they would benefit from decreasing or gaining weight to improve their fertility. A BMI of less than 18.5 (underweight) or more than 30 (obesity) may indicate that a patient’s weight is harming their fertility.
