Women are seeking someone to take care of the child after ovulation. The hormone profile = lower testosterone + lower estrogen (preferably + lower cortisol). Similar to the profile pushed toward by progesterone, the hormone elevated during that time.none on hand unfortunately, its been a while. googling for birth control and partner preferences may yield some results. if i remember correctly it was basically stated that women on the pill tend to prefer „safer“ and genetically more similar men , as if they were pregnant. thats on top of what estrogens and progestins do to the body as a whole
