The use of hormonal contraceptive pills, including birth control pills, plays a significant role in altering sexual behavior and desires of women as well as their attractiveness towards men, claims a recent study. During the course of the study, it was observed that women prefer the body odour of men who have an immune system exactly different from that of women’s immune system gene, MHC.
The research, accomplished by the Duke University on female lemurs, has revealed that hormonal contraceptives have changed the female attraction towards the males.
Further, women using contraceptive pills have complained about swings in their libido as well as in the mood along with changed sexual desires during the monthly cycle. At the time of ovulation, women tend to behave flirtier and wear sexier cloths and emit chemicals that attract men. On the other hand, a woman with birth control pills lacks such chemical changes.
However, Dr. Haselton said that the derived data cannot be considered enough to conclude anything significant about the mood fluctuations. "It is certainly possible that if women don't experience that little uptick in [desiring] masculinity that they end up choosing less masculine partners”, she added.
