Show Summary Details


This chapter explores the emerging field of semen and vaginal chemistry as it relates to the evolution of reproductive competition between males and females. Not only is the vagina ideally suited for drug delivery, human semen contains features that appear to promote the male’s reproductive best interests. This has lead to an ongoing series of chemical, physiological, and behavioral adaptations by women and corresponding counter-adaptations by men (e.g., female immune reactions to sperm and ensuing immunosuppressant properties of semen).

Keywords: semen; seminal plasma; infidelity; rape; preeclampsia; mate choice; immune reactions to semen; paternal uncertainty; parasitizing rival male ejaculates
