competitiveness and menstural cycle

 

AUGUST 14, 2012 Tuesday Women's Competitiveness Drops When Fertility Is Low Women who use contraceptive pills are 50% less competitive during the 21 days of the month when they take the drug, which contains the sex hormone progesterone, according to Thomas Buser of the University of Amsterdam. Moreover, in an experiment involving compensation schemes for a problem-solving task, women were 10.5 percentage points less likely to opt for a competitive scheme if they were at the point in their monthly cycles when fertility was low because progesterone levels were high. The findings are consistent with evolutionary theories positing that competitiveness is less useful for women during the infertile phase of the ovulation cycle. Some researchers have said that aversion to competition may help explain the low number of women in top corporate positions. Source: The impact of the menstrual cycle and hormonal contraceptives
