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. And when the amount of fat is large, an excessive hormone release is observed, which leads to hormonal imbalance.
Excess weight and infertility are related, i.e. the first can cause the appearance of the second. This condition reduces the chances of conceiving as well as 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 is an indication for 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 6 months in a row). Moreover, excess weight can be a root cause of infertility and vice versa.
Excess weight and infertility are interconnected by the following factors:
Changes in the concentration of sex hormones and the violation of their production;
The development of type 2 diabetes disrupts carbohydrate metabolism, decreases the sensitivity of tissues 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 as a result of hypothyroidism (a violation of the synthesis of thyroid hormones), resulting 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, in this case, complications during pregnancy are not excluded. Therefore it is recommended to lose at least 10% of the weight.
Increased body weight is one of the causes of male infertility. The presence of a large amount of fat leads to an increase in 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, and 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 reduced. The likelihood of developing diabetes in obesity in men and women is the same.
Overweight and infertility in men are also interrelated, i.e. extra pounds affect:
Obesity, unlike women, in the stronger sex is not a guarantee of infertility, it only reduces the chances of conception.
