Birth Control Pills Affect Women's Taste in Men

Nowadays the divorce rate is raising in every corner of the world. Recent studies have shown that birth control pills could alter which type of men women like.

Normally, women tend to prefer men with a different major histocompatibility complex (MHC), a group of genes involved in the immune system. This is probability relate with the fact that children whose parents have a different MHC have a better immune system. Women can have a clue to a man's MHC by scent.

However, when taking the pill that simulates pregnacy, women's taste is affected. Recent studies reveled that women on the pill find more atractive men with similar MHC.

So, if during a relationship women start or stop to take the pill the relationship could be in trouble. Moreover, there are studies that state that women coupled with men with similar MHC are more likely to cheat and less sexualy satisfied. To sum it up, a woman taking the pill will more likely choose a MHC-similar man. If she stop taking it, she could be less sexualy satisfied, her taste would change, and she would be more likely to cheat.
