New Study: Oral Contraceptives Disrupt Ability to Choose Genetically Favorable Mate

LIVERPOOL, United Kingdom, August 12, 2008 ( – A recent study by the University of Liverpool found that the contraceptive pill may adversely affect a woman’s natural ability to choose a genetically favorable mate.  The ability to choose a genetically favorable mate is ascribed in part to pheromones, chemicals that can cause behavioral changes in the opposite sex. These chemicals also contain the genes involved in immunity response.  When these genes interact with normal skin bacteria, they influence an individual’s particular body odor. 

Research has indicated that women tend to be more attracted to the odors of men whose genes are more unlike their own; this instinctive attraction is key in helping ensure a match that is genetically advantageous to a couple’s offspring.  If a couple’s genes are too similar, they are at an increased risk of miscarriage and difficulty conceiving, and if they do conceive, the child may have a weakened immune system.

Yet this natural sense may be endangered by the use of oral contraceptives.  The research team conducting the study asked women to indicate their preferences of six male body odors before and after initiating use of oral contraceptives. 

According to Craig Roberts, a Lecturer in Evolutionary Psychology and one of the researchers in this study, women taking the pill began to prefer men with more genetically similar odors.  Addressing the implications of such a disruption, he states: “Not only could [gene] similarity in couples lead to fertility problems, but it could ultimately lead to the breakdown of relationships when women stop using the contraceptive pill, as odour perception plays a significant role in maintaining attraction to partners.”

These claims are not the first to question the pill’s impact on hormone activity and sexuality.  Dr. David Brownstein, commenting on a study linking oral contraceptives to increased arterial plaque, emphasized the precarious balance of hormones needed for good health, a balance disrupted de facto in pill users:

“Oral contraceptives totally disrupt the normal hormonal cascade. When the hormonal system is disrupted, cardiovascular disease, cancer, fibromyalgia, chronic fatigue syndrome and other serious illnesses will increase.  My clinical experience has clearly shown that it is impossible to adequately treat these illnesses if there is an imbalanced hormonal system.”  (Read “Oral Contraceptives May Be Linked to Atherosclerosis”

In addition to altering women’s natural attraction to suitable partners, the pill also permanently damages sex drive over long-term use, according to one study (Read 

So not only does the Pill cause major health consequences and exponentially increase your chance of divorce, but it also makes you stupid too?

The Pill.

Isn’t it great?

  1. Another other “great” thing about the pill and our culture of death is that it kinks the evolutionary hose. If a person believes the science that tells us that we evolve by Natural Selection passing down beneficial mutations from generation to generation, then we are interrupting that process by contracepting and aborting. There’s a lot to be said for the simple holistic elements in Natural Family Planning.

  2. Check me if I am wrong but I seem to remember Pope Paul VI saying something similar back in 1968 in an encyclical on human life which condemned artificial birth control as being contrary to catholic beliefs. This would make the second time in the twentieth century that the Catholic Church was right and popular opinion was wrong. In the 1920’s the Catholic Church condemned eugenics when popular opinion supported the idea of forcibly sterilizing people whom society deemed unfit to reproduce. The renowned jurist Oliver Wendel Holmes wrote a majority decision of the U.S. Supreme Court which upheld the State of California right to sterilize a “feeble minded” woman who bore a child outside of wedlock. Such atrocities were not confined to Nazi Germany.
