Podobno tylko heteroseksualne, których partnerzy nie używają gumek ;)

"Our interest in the psychological properties of semen arose as a by-product
of an initial interest in menstrual synchrony," explain co-discoverers
Gordon Gallup and Rebecca Burch, evolutionary psychologists from the State
University of New York system, in a 2006 chapter about human semen. In
particular, Gallup and Burch had stumbled onto a set of intriguing data from
the mid-1990s showing that, unlike heterosexually active women residing
together, sexually involved lesbians failed to exhibit the well-known
"McClintock effect," in which menstrual cycles in cohabitating women (as
well those of females from many other species) are synchronized. Since
subtle olfactory cues (called pheromones) are known to mediate menstrual
synchrony, write the authors, "This struck us as peculiar..."

. because lesbians would be expected to be in closer, more intimate
contact with one another on a daily basis than other females who live
together. What is it about heterosexual females that promotes menstrual
synchrony, or conversely what is it about lesbians that prevents menstrual
synchrony? It occurred to us that one feature that distinguishes
heterosexual women from lesbians is the presence or absence of semen in the
female reproductive tract. Lesbians have semen-free sex.


Perhaps you already see where this is leading. Gallup and Burch reasoned
that certain chemicals in human semen, through vaginal absorption, affect
female biology in such a way that women who have condomless sex literally
start to smell different from those women who do not-or at least, their
bodies emit the pheromones that "entrain" menstrual cycles among
cohabitating women. (Their hunch was indeed borne out by reviewing the
existing literature on menstrual synchrony.)
