Indeed, previous experiments have shown that women report getting more pleasure from cocaine and amphetamine use during the follicular phase compared to the luteal phase, says Dreher. He believes his findings may therefore help treat women with drug abuse problems, or those with mood disorders.
Dreher also speculates that increased feelings of reward during the follicular phase—when a woman is ovulating and therefore most likely to get pregnant—may have an evolutionary benefit. “It is interesting to note that, from an evolutionary perspective, the increased availability, receptivity and desire that may occur during the ovulatory period has been thought to facilitate procreation,” he says.
Really? That goes against everything I know of the phenomenon.
