Birth control conspiracy

There is conspiracy story making the rounds and could very well be true. Married women are in greater numbers becoming increasingly frigid. They have lost their sexual drive I believe it is called libido. The sperm count in men has fallen too. Whatever chemical is being put in the food and water is resulting in this drop in fertility. Since wives do not have any sexual desire their husbands cannot go to them. Even if some women manage to retain their libido, their husband's sperm would not result in the birth of a child. Families do not extend beyond one or two children, not because they do not want to have more children, it is because of some kind chemicals have been inroduced either in the environment or in the food or water that most married couples lead absolute sexless lives. The chemical's effect is so great that women have a growing aversion to anything pertaining to sex. While the husbands have the sexual drive but are not in a position to father children even if they do have the rare chance of sexual intercourse. More and more men are seriously considering abandoning their wives and to marry other women who can give them intimacy and sex. The number of divorces have increased - women leave their husbands because of their dislike of sex and men divorcing their wives because of the lack of any sexual relationship.
Some people theorised that the reason why this is happening is because of money. But what is conveniently forgotten is that the poor and the wealthy both have had plenty of children. If money was a factor then the poor would never children only those with money would. But the problem is affecting both. Fewer children are being born. What better way of wiping out an entire nation then by reducing its population, instead of killing them not allowing more to be born. This may sound like science fiction but it does seem eerily more like science fact.
