The problem of obesity has reached critical levels in some countries and is growing in India. According to a piece published by NDTV in 2014, India ranks third behind the U.S. and China, with 41 million people considered obese. The health problems associated with being overweight are many, and fertility problems are no exception.
While planning a pregnancy, women are often advised on how to change their lifestyles by reducing weight, cutting their intake on sugary &caffeinated drinks, stop smoking and drinking if they want to conceive and have a healthy pregnancy. More preference is given to the health of women when trying to conceive. The focus is less on the lifestyle choices of men, but it should be kept in mind that it takes two to conceive. The overall health of both partners must be considered for a healthy conception. Also, according to a new study, it has been found that men's health can have a more significant effect on a couple's chances of conceiving by adversely affecting sperm quality.
Research says that there is a connection between a man's weight and his potential fertility. There are many emerging studies which prove that male obesity adversely impacts fertility through changes in the hormonal levels affecting sperm production, which results in low sperm count. Besides, in these men, sperm motility (movement: which is necessary to swim up in the female reproductive tract) was also found to be poor. Due to reduced sperm motility and low sperm count, it becomes difficult for these men to conceive. If this kind of obesity trend continues, then more and more men will have problems in reproducing.
Fertility specialists nowadays handle cases where up to a third of couples who come to seek help in conceiving deal with male-factor infertility, and so it has become necessary for researchers to investigate that how a man's lifestyle may affect his fertility. This topic is still not clearly understood, but specialists believe that some theories can explain how excess body fat impacts male fertility, and the theories are as below:
Due to obesity, changes happen in sperm function and sperm molecular composition, and this affects the overall quality of the sperm. Poor sperm quality can lower fertility thereby affecting the chances of conception. Semen parameters in these men were found to be altered as excess weight can be linked to a lower volume of semen, lower sperm counts and lower sperm concentration. In case both the parents are obese, then parental obesity at conception can have harmful effects on the embryo health, its implantation, consequently pregnancy and birth rates. In such cases losing weight could improve sperm and egg quality.
