Stronger, More Athletic
In naturally cycling women [women not on contraceptives suppressing ovulation] there was a significant increase of about 11% in quadriceps and handgrip strength at mid-cycle.
-Sarwar et al (1996)
The knee (or one its major ligaments, the ACL) contains hormone receptors—including receptors for estrogen. Women are three times more likely to injure their ACL during ovulation than during other times of their cycle.
-Belanger (2013), Zazulak (2006)
Lightning Fast Reflexes for Language
Verbal reflexes--speed, articulation, accuracy--are superfast now as women approach ovulation and climbing estrogen peaks.
Wired for Reward!
Before ovulation, women’s brains respond to reward more than at other times. They feel the pleasure of winning more keenly. After ovulation, rising progesterone crashes the party which can strip away that sharp sense of triumph. This could explain PMS, or even why women “are more vulnerable to addictive drugs” before ovulation.
Ask for her # THIS week
Women are more receptive to men now. During the ovulatory part of their cycle, women were more likely to give their phone number to random male strangers who approached them in a park.
Women report greater interest in going out to dance clubs and parties to meet men than on non-fertile days.
-Haselton & Gangestad (2006)
Female On Female
Lesbian sexuality shows same surge at ovulation.
--Matteo (1984), Burleson (2002)
Women put more care and attention into self-ornamentation. They wear more jewelry, make-up, and show more skin. People judge photos of the faces of ovulating women to be sexier (compared to photos of the same women two weeks earlier).
-Haselton (2006) , Durante, Li, & Haselton (2008)
Women’s waists shrink by a half inch, enhancing the hourglass shape.
Facial skin is relatively unblemished, smooth, and hairless due to high estrogen concentrations.
Women’s voices take on a higher pitch, which is regarded as more attractive, more feminine, by both men and women.
-Bryant (2009), Pipitone & Gallup (2008)
Fertility Can Cause Cattiness
Women during fertile days put down the competition, ranking other women as less attractive during the very phase when their own reproductive stakes are high.
-M.L. Fisher (2004)
At ovulation women report heightened awareness of other women as competitors. They are more inclined to see other women as the competition, but only in their local environment--not with women thousands of miles away.
-Durante, Griskevicius et al (2010)
At ovulation a woman is more concerned with relative status, how she ranks compared to the other women in her group.
-Durante et al (2008)
At ovulation women share fewer resources with women and more with men.
-Lucas, Koff, & Skeath (2007)
I Need It Now
Women Initiate Sex
The ovary oozes with estradiol (an estrogen) during the most fertile days of the cycle. Two reasons: 1) To thin the cervical fluid so sperm can move quickly. 2) To boost motivation to interact with men.
-Evolution and Human Sexual Behavior, Gray & Garcia, (2013)
Women make more eye contact with male strangers.They look not to learn but to signal interest. Non-verbal solicitation is mainly done by the female and common signals include direct eye contact, outstaring, fixing the gaze on the target male then breathing synchronously.
Female primates stare at males and then flick their tongues. This pairing of signals is an invitation for the male to mount.
Women feel greater impatience now, want immediate rewards.
-Dreher et al, (2007)
Women possess more confidence during ovulation; they perceive themselves as sexier.
-Haselton & Gangestad, (2006)
“No Time to Eat”: Women devote more time and attention to mating concerns. They range farther from home and are less motivated to eat. They explore the environment more.
Visual attention is sharper during these few days.
-Barris (1980), Colzato, (2011)
Women are more likely to wear red or pink at peak fertility.
-Beall & Tracy (2013)
Both women and men perceive a woman in a red dress to be more sexually receptive than a woman in white. Women are more likely to derogate the sexual fidelity of a woman in red than a woman in white. Women are more likely to guard their romantic partner from a woman wearing red compared to green.
The Pill Makes Her Less Sexy
Surprising Effects of the BC Pill
The BCPill works by keeping progesterone and estrogen dosed in such a steady way that ovulation is prevented. Sure enough, women on the birth control pill don’t experience the same fluctuations—either the lusty behavior of midcycle or the devastating lows of PMS.
-Alvergne & Lummaa (2010)
Strippers earn higher tips when they perform during their fertile days…unless they’re on the birth control pill, in which case they’re not getting the surge of estrogen. These women’s tips do not spike midmonth.
-Miller, Tybur, & Jordan (2007)
Captive female lemurs on birth control suppressing ovulation didn’t get as much attention from male lemurs. The reason? Birth control radically changes a fertile female’s signature scent.
-Crawford, Boulet, & Drea (2010)
The peak of mid-cycle sexuality and trough in luteal phase is a pattern which is altered by the administration of contraceptive pills.
-Udry, Morris, & Waller (1973)
“I Could Do Better” or “Lucky Me”
How A Woman Feels Midcycle could depend on her man’s T:
Women with Low-Testosterone men are more critical of their partners now—as if their standards are raised during the 2-3 days around ovulation.
Women partnered with Low-Testosterone men are more likely to cheat now than at other times in cycle.
Women look less for partnership and more for good genes. They are more likely than usual to sleep with someone they don’t care about.
-Larson et al (2012)
WANTED : Symmetry
Women subconsciously scan for
a symmetrical face now.
If he has a symmetrical face, then:
- she has more orgasms during sex
-Thornhill & Gangestad, (1995)
- he has social presence, and doesn’t back down from other men
-Gangestad et al, (2003, 2004)
- he tends to be high on general intelligence
- compared with other men, he smiles less
- he prefers to womanize rather than invest in a long-term relationship
- he’s less honest, more likely to cheat
-Gangestad & Thornhill, (1997)
- he’s more likely to antagonize other men, and engage in fights
- he is less interested in romance
-van der Meij, (2008)
- he has a higher number of sex partners
-Van Dongen (2008)
The shift in taste for men is an unconscious one brought about by hormonal changes. Women’s saliva levels of estradiol (the estrogen that’s highest at ovulation) predicts changes in desire for men with facial features shaped by testosterone.
-Roney, Simmons, Gray, (2011)
