Can obesity cause fertility problems?

You are unsuccessfully trying to get pregnant and you do not know what is causing the problems? Consider which weight category you and your partner can be classified into. Clinical studies indicate that obesity is a factor significantly increasing the risk of experiencing fertility problems in both sexes.

The easiest way to diagnose obesity is calculation of body mass index, also known as BMI (Body Mass Index). This factor can be obtained after performing a simple operation - the weight should be divided by the height given in meters and raised to the square. If the number obtained is equal to or higher than 30, it means obesity.

How does excess weight affect a woman's fertility?

The development of obesity leads, among others for carbohydrate disorders, which is responsible for the proper functioning of the ovaries. The result of such changes may be a decrease in the regularity of ovulation and an increase in the frequency of anovulatory cycles. In addition, excessive body weight increases the likelihood of developing polycystic ovary syndrome - a disease which is one of the most common causes of female infertility.

Obesity and pregnancy complications

Obese women are much more likely to have postpartum complications or complications during pregnancy. Excessive body weight can contribute to the development of, among others ailments such as gestational diabetes, hypertension, preeclampsia or thrombosis. Mother's weight can also have a direct impact on the health of the fetus - the largest number of miscarriages and the birth of dead children is recorded among women suffering from obesity or severe overweight. People with excessive body weight are also much more likely to undergo cesarean delivery or artificial delivery.

How does excess body fat affect male fertility?

The development of obesity can significantly affect sperm parameters. According to specialists, ejaculate of people with normal BMI is more valuable because it contains more sperm - in addition, they show higher mobility. Clinical studies show that an average of 18.6 million mobile sperm are found in the body of a man maintaining optimal body weight, while the ejaculate of an obese man contains only 0.7 million.

The decrease in the quality of sperm produced is a result of hormonal disorders. The process of transforming testosterone into estrogens occurs in adipose tissue. Because of this, men with excessive body weight often experience disturbances in the ratio between male and female sex hormones. Another factor affecting the quality of ejaculate in obese men is the increase in testicular temperature. The optimal temperature of this organ plays a key role in the process of producing healthy and strong sperm.

Are fertility problems permanent?

Fertility disorders experienced by people who are overweight or obese are not permanent. Studies show that a 5% weight loss significantly increases the likelihood of becoming pregnant. Losing excess weight can have a positive effect on the course of the menstrual cycle and improve the quality of ejaculate.
