There was another digit study of homosexuality correlating to digit ratios. For hetero men and lesbians, the 4D should be longer than the index finger. For homosexual men and hetero women, the index finger should be longer than the fourth digit.
It's caused by the amount of estrogen in the mother when she carries the child.

There are many phenotypic markers of heterosexual development that are slightly altered in homosexuals. 2D:4D is one that has been studied by many groups. Androsterone/etiocholanolone ratios, which probably are manifest in male scent signatures that vary with sexual orientation, is a phenotypic marker that has not been studied since the early 70's -- with few exceptions, of course.

Thanks for the link Jvkohl, I'll have a read of the paper when I get some free time, one thing that did jump out at me is the paper listed in the References by Thornhill et al:
Thornhill, R. & Gangestad, S. W. 1999 The scent of symmetry: a human sex pheromone that signals ï¬tness?
Its available here for anyone who is interested:
https://www.ceacb.ucl.ac.uk/cultureclub/...rnhill.pdf
KEY WORDS: Androgens; Androstenone; Androstenol; Developmental instability; Fluctuating asymmetry; Handicap theory; Mate choice; Menstrual cycle; Pheromones; Sexual selection; Signaling.
Do you have any thoughts on that specific paper?
Thanks

Fascinating...
Quote: Moreover, men's symmetry predicts a relatively high frequency of their sexual partners' copulatory orgasms (Thornhill et al. 1995). Female copulatory orgasm may be a mechanism of cryptic female choice in contexts in which women mate with multiple partners (Baker and Bellis 1995)
And this sounds like androstenone to me...
Quote:Compared to the body scent of relatively asymmetric men, relatively symmetric men's scent is more attractive to normally ovulating (non-pill-using) women during their period of peak fertility based on menstrual cycle point. Yet non-pill-using women show no odor preference related to male body symmetry during menstrual cycle times of low fertility. Moreover, women using hormone-based contraception do not show the preference.
