Sperm competition may select for male reproductive traits that influence female mating or oviposition rate. These traits may induce fitness costs to the female; however, they may be costly for the males as well as any decrease in female fitness also affects male fitness. Male adaptations to sperm competition manipulate females by altering not only female behaviour or physiology, but also female morphology. In orb-weaving spiders, mating may entail mutilation of external structures of the female genitalia, which prevents genital coupling with subsequent males. Here, we present a game theoretical model showing that external female genital mutilation is favoured even under relatively high costs of mutilation, and that it is favoured by a high number of mate encounters per female and last-male sperm precedence.

A condition of sexual ambiguity in which the individual (pseudohermaphrodite) possesses gonadal tissue of one SEX but exhibits external PHENOTYPE of the opposite sex. Female pseudohermaphroditism is an individual with XX karyotype, normal development of OVARIES and internal reproductive tract, but with ambiguous or virilized external GENITALIA. Male pseudohermaphroditism is characterized by the presence of a Y CHROMOSOME and TESTES, but the genital tract and external genitalia are ambiguous or completely female.
A familial form of PSEUDOHERMAPHRODITISM transmitted as an X-linked recessive trait. These patients have a karyotype of 46,XY with end-organ resistance to androgen due to mutations in the androgen receptor (RECEPTORS, ANDROGEN) gene. Severity of the defect in receptor quantity or quality correlates with their phenotypes. In these genetic males, the phenotypic spectrum ranges from those with normal female external genitalia, through those with genital ambiguity as in Reifenstein Syndrome, to that of a normal male with INFERTILITY.
