Journal ArticleDOI
MHC-correlated mate choice in humans: A review
Jan Havlíček,S. Craig Roberts +1 more
TL;DR: The idea that olfactory and visual channels may work in a complementary way to achieve an optimal level of genetic variability, methodological issues and interesting avenues for further research are discussed.
Journal ArticleDOI
Female facial attractiveness increases during the fertile phase of the menstrual cycle
S. Craig Roberts,Jan Havlíček,Jaroslav Flegr,Martina Hruskova,Anthony C. Little,Benedict C. Jones,David I. Perrett,Marion Petrie +7 more
TL;DR: It is shown here that both men and women judge photographs of women's faces that were taken in the fertile window of the menstrual cycle as more attractive than photographs taken during the luteal phase, indicating the existence of visible cues to ovulation in the human face.
Journal ArticleDOI
Women's preference for dominant male odour: effects of menstrual cycle and relationship status
TL;DR: It is shown that women in the fertile phase of their cycle prefer body odour of males who score high on a questionnaire-based dominance scale (international personality items pool), and this preference varies with relationship status, being much stronger in fertile women in stable relationships than in fertile single women.
Journal ArticleDOI
Increased risk of traffic accidents in subjects with latent toxoplasmosis: a retrospective case-control study.
TL;DR: The results suggest that 'asymptomatic' acquired toxoplasmosis might in fact represent a serious and highly underestimated public health problem, as well as an economic problem.
Journal ArticleDOI
Decrease of psychomotor performance in subjects with latent 'asymptomatic' toxoplasmosis.
TL;DR: This is the first study confirming the existence of such parasite-induced changes in human behaviour that could be considered in evolutionary history of the human species as adaptive from the point of view of parasite transmission.
