pertaining to sex.

includes masturbation, courtship, mating, estral display.
sexual cycle

sexual differentiation
identification of the sex of a patient is done usually by an examination of external genitalia; preparation and examination of a karyotype is the preferred laboratory method.
sexual dimorphism
differences in structure or physical characteristics between males and females of the same species, e.g. horns in some breeds of sheep, feather coat color in many species of birds.
sexual intercourse
see mating.
sexual maturity
capable of mating. Occurs at different ages in different species and in different races and even breeds.
sexual receptivity
behavioral changes in female animals at the time of estrus; involves acceptance of male efforts at copulation and, in some species, actively seeking the male.
