There are several factors that can affect fertility, including body weight. When you are trying to conceive, certain lifestyle changes, including maintaining an optimal BMI (body mass index), can help you increase your chances of pregnancy and achieve your goals. Our team at the Fertility Center of San Antonio in San Antonio, TX, can speak with you about BMI and infertility during a consultation.
Obesity and Fertility
We know that obesity can have a negative impact on overall health. It only makes sense that extra body weight can have a direct influence on fertility. For example:
- Women who are overweight are less likely to become pregnant at all.
- Those who are overweight are twice as likely to develop gestational diabetes, while those who are obese are eight times as likely.
- Babies born to obese woman are more likely to struggle with obesity. They also have a higher risk for congenital abnormalities.
- Women who are obese are twice as likely to have a miscarriage.
Women who have a BMI over 30 may improve their chances for pregnancy by losing weight. In some cases, weight loss can address disruption in the ovulation cycle. So if you are overweight and notice that your menstrual cycle is irregular, weight loss could regulate it. In turn, this could improve your chances for pregnancy.
Low BMI and Fertility
Many people assume that being overweight is the only BMI issue affecting pregnancy. On the contrary, being underweight can have a significant negative impact on fertility as well. In fact, compared to women of a healthy weight, those who are underweight are over twice as likely to take more than 12 months to conceive. This is primarily due to hormone imbalances that can directly affect ovulation. If you have a BMI under 18.5 and are having difficulties conceiving, you may want to consider healthy ways to gain weight.
Male Factor Infertility and BMI
Several patients are surprised to hear that BMI in men can also have a direct impact on fertility. Being overweight or underweight can lead to significant changes in the body. This can sometimes affect hormone regulation and sperm production, causing low sperm count or low motility.
What Normal BMI Can Do for Your Fertility
When your BMI is considered normal, you can expect a reduced risk of complications, not only for you, but for your baby as well. According to the Institute of Medicine, normal weight is indicated when the BMI is between 18.5 and 24.9. These couples respond better to fertility treatments when compared to those who are underweight or overweight.
