Will Obesity Leads to Infertility?
It is a known fact that obesity will cause many chronic diseases and sometimes can leads to death also. But nowadays a new question has arrived that will it lead to infertility? Yes!! It also affects fertility. Both men and women have the same risk. In women, the menstrual cycle is regulated by a fine hormonal balance. In the case of overweight and obese women have higher levels of a hormone called leptin, which is produced in fatty tissue. This leptin can disrupt the hormone balance and lead to reduced fertility.
This disruption may lead to irregular menstrual
cycles, which in turn reduces fertility. Studies have proven that women
with overweight cannot conceive within one year of stopping contraception but
in cause women with normal weight range will not have any such problems. Such
changes in the menstrual cycle generated by excess weight and obesity also
increase the risk of anovulation (when no egg is released by the ovaries).
Many women can ovulate, even with excess weight this
will affect the quality of the eggs they produce will be reduced. Women with BMI
of 35, the likelihood of getting pregnant within a year is 26% lower, and for a
woman with a BMI of 40, it is 43% lower compared with women with a BMI between
21 and 29.
In men, obesity is also associated with lower
fertility. The factors of
infertility in men are a bit similar to women. These include hormone
problems, sexual dysfunction and other health problems which are linked with
obesity such as type 2 diabetes and sleep apnea which are both associated with
lowered testosterone levels and erectile problems.
The facts about obesity and fertility can seem to be scary,
but there is good news too. Intervention in weight-loss
such as both diet and exercise can promote menstrual cycle regularity and improve
the chance of pregnancy. Even a modest weight loss of 5-10% in obese women can
improve fertility and the chance of conceiving.
