• These preferences may be a consequence of ancestral humans who selected partners based on general
indicators of fitness
which allowed for
greater reproductive
success as a result
of higher fertility in
those partners Little, A. C et al , Behav Ecol Sociobiol, 2006

• In short-term relations, women prefer more masculine faces at peak fertility of the menstrual cycle to enhance her offspring's quality
• But for marriage, preference is for feminine faces.

• During ovulation there is an increase in T levels of human males, ie, somehow, the female was signaling the male that she had ovulated, and that he responded
• Increased T may lead to increased intercourse

• Women and men were typed for their HLA-A, -B and –DR
• Women were asked to
rate the odors of T-shirts
worn by the men for 3 days• Women scored male body
odors as more pleasant
when these men had a
different MHC than when
they were more similar

• This difference in
odor assessment
was reversed when
the women rating
the odors were

genes influence human mate choice Wedekind C, Proc. R. Sac. Land. B , 1995
