Effect of Over weight
Most of us are facing obesity problem throughout the industrialized world and a series of cautions about this growing problem from the rest of the world. This fact creates lots of questions about how obesity would influence millions of lives have been raised. Actually, there is no research have been performed yet to find this. But there are several indirect links between obesity and decrease in the quality of sperm that science has already identified. The fact that overweight and obese people tend to cut down on effort whenever they can has a big influence on sex. It is because regular effort is crucial to the secretion of testosterone by the body. Testosterone influences the sex drive and the growth of spermatogenic tissue in the testes. It does not regulate the quality of sperm. Spermatogenic tissue performs the very production of sperm. If the level of one’s testosterone decreases, which is bound to happen to every "couch potato" person who tends to avoid effort, his libido may drop. Then if one has his libido drop, he is no longer as interested in sex as before, not does he get as much pleasure from it as he used to. Combined with the frequent exposure to substances that mimic the effects of the estrogen hormone, the low level of testosterone may set off shrinking penis and testicles.
