Are overweight and infertility related?

Obesity is a disease in which the volume of body fat in a person is large, and the body mass index exceeds 25 kg / m2. Excess weight provokes the emergence of many diseases, including infertility, in both men and women. Infertility in women occurs as a result of violations of the production of sex hormones. Adipose tissue is also capable of producing hormones. Besides, when the amount of fat is significant, an excessive hormone release occurs, which leads to hormonal imbalance. Overweight and infertility are related, i.e. the first can cause the appearance of the second.

This condition reduces the chances of conceiving. It also represents a risk of miscarriage or the threat of premature birth. Gestational diabetes, hypertension, varicose veins, thrombosis and other diseases can develop during pregnancy. Also, the fetus may be too large in women with an overweight of 75%, which indicates a cesarean section.

Those suffering from obesity have an irregular menstrual cycle, which is primarily associated with impaired egg maturation. Often there is amenorrhea (absence of menstrual bleeding for more than six months in a row). Moreover, excess weight can be a root cause of infertility and vice versa.



Excess weight

The following factors interconnect overweight and infertility:

Changes in the concentration of sex hormones and the violation of their production;

The development of type 2 diabetes disrupts carbohydrate metabolism and decreases tissues’ sensitivity to glucose, resulting in insulin resistance. Elevated levels of insulin in the blood leads to the hormonal imbalance of sex hormones, which disrupts the development of the egg and, as a result, a woman cannot conceive a child.

Obesity resulting from hypothyroidism, which violates the synthesis of thyroid hormones, results in reduced fertility.

The likelihood of pregnancy in obesity depends on the reasons that caused the disease. If the appearance of excess weight has contributed to poor diet and lack of exercise, while a woman has regular menstrual bleeding and hormone levels are more or less healthy, then conception occurs without problems. However, cases like that do not exclude complications during pregnancy. Therefore, we recommend losing at least 10% of the weight.

Are overweight and infertility associated with the male half of the population?

Increased body weight is one of the causes of male infertility. The presence of a significant amount of fat increases the concentration of prolactin and a decrease in testosterone.

Violation of the functions of sex hormones in men affects the process of maturation of spermatozoa. Then a small number of motile sperm is determined according to the results of spermograms. With this condition, the chances of conceiving a child are reducing. The likelihood of developing diabetes in obesity in men and women is the same.

Extra pounds

Overweight interrelates with infertility in men too, i.e. extra pounds affect:

  • On sperm motility and sperm quality.
  • On the blood circulation, when the blood supply is disturbed. As a result, the potency weakens. In this case, the inability to implement full sexual intercourse causes infertility.
  • On the urinary system. Violation of the urinary sphincter function, which provokes retrograde urination.

Obesity, unlike women, in the more vigorous sex is not a guarantee of infertility. It only reduces the chances of conception.
