How Does Weight Affect Fertility?
Scientific research shows that weight can have a significant impact on the time it takes for a healthy woman to become pregnant. Being overweight, obese, or underweight can negatively affect the menstrual cycle, egg development, and overall ability to conceive.
In men, studies have indicated that obesity may reduce seminal quality, resulting in lower sperm concentration and abnormal sperm morphology.
For the best chance of achieving pregnancy, it is recommended to maintain a weight within the normal range.
How Do I Know if My Weight Is Right for Conception? What Are the Risks?
Rather than focusing solely on weight, it's important to consider your Body Mass Index (BMI). Many online BMI calculators can help determine this value. According to WHO recommendations:
A BMI less than 18.5 indicates excessive thinness, which is associated with ovarian dysfunction and an increased risk of preterm pregnancy.
A BMI between 18.5 and 25 is considered normal weight, providing ideal conditions for safe conception.
A BMI between 25 and 30 indicates overweight.
A BMI over 30 indicates obesity, which is linked to higher rates of cycle cancellations, lower embryo implantation rates (due to reduced endometrial receptivity), and increased rates of miscarriage. Obesity is also associated with a higher likelihood of gestational complications, such as gestational diabetes.
What Can We Do if We Are Not at the Right Weight to Conceive?
As we’ve seen, maintaining the right weight is essential for achieving a healthy pregnancy. Fortunately, many of the negative effects on fertility are reversible if addressed in time.
The main recommendations are simple: improving your diet and increasing physical activity, along with monitoring by a healthcare specialist, can help prepare your body for pregnancy.
