She added that Lloyd "meticulously considers the theoretical and empirical bases for each account and ultimately concludes that there is little evidence to support an adaptionist account of female orgasm" and that Lloyd instead "views female orgasm as an ontogenetic leftover; women have orgasms because the urogenital neurophysiology for orgasm is so strongly selected for in males that this developmental blueprint gets expressed in females without affecting fitness, just as males have nipples that serve no fitness-related function".A 2005 twin study found that one in three women reported never or seldom achieving orgasm during sexual intercourse, and only one in ten always orgasmed. This variation in ability to orgasm, generally thought to be psychosocial, was found to be 34% to 45% genetic. The study, examining 4000 women, was published in Biology Letters, a Royal Society journal. Elisabeth Lloyd has cited this as evidence for the notion that female orgasm is not adaptive.Miller, Hrdy, Helen OConnell and Natalie Angier have criticized the "female orgasm is vestigial" hypothesis as understating and devaluing the psychosocial value of the female orgasm. Hrdy stated that the hypothesis smacks of sexism. OConnell said, "It boils down to rivalry between the sexes: the idea that one sex is sexual and the other reproductive. The truth is that both are sexual and both are reproductive." OConnell used MRI technology to define the true size and shape of the clitoris, suggesting that it extends into the anterior wall of the vagina (see above).
