Gynophobia or gynephobia is an abnormal fear of women, a type of specific social phobia. In the past, the Latin term horror feminae was used.

Gynophobia should not be confused with misogyny, the hatred, contempt for and inveterate prejudice against women, although some may use the terms interchangeably, in reference to the social, rather than pathological aspect of negative attitudes towards women.

An antonym is philogyny, the love, respect for and admiration of women.

Gynophobia was previously considered a driving force toward homosexuality. In his 1896 "Studies in the Psychology of Sex", Havelock Ellis wrote:

It is, perhaps, not difficult to account for the horror – much stronger than that normally felt toward a person of the same sex – with which the invert often regards the sexual organs of persons of the opposite sex. It cannot be said that the sexual organs of either sex under the influence of sexual excitement are esthetically pleasing; they only become emotionally desirable through the parallel excitement of the beholder. When the absence of parallel excitement is accompanied in the beholder by the sense of unfamiliarity as in childhood, or by a neurotic hypersensitiveness, the conditions are present for the production of intense "horror feminae" or "horror masculis", as the case may be. It is possible that, as Otto Rank argues in his interesting study, "Die Nacktheit in Sage und Dichtung," ["sic"] this horror of the sexual organs of the opposite sex, to some extent felt even by normal people, is embodied in the Melusine type of legend.

In his book "Sadism and Masochism: The Psychology of Hatred and Cruelty", Wilhelm Stekel discusses "horror feminae" of a male masochist.

In "The Dread of Woman" (1932), Karen Horney traced the male dread of woman to the boy's fear that his genital is inadequate in relation to the mother.

Professor Eva Keuls argues that violent Amazons are the evidence of the obsessive fear of women in Classical Athens.

Rape trauma syndrome (RTS) is the psychological trauma experienced by a rape victim that includes disruptions to normal physical, emotional, cognitive, and interpersonal behavior. The theory was first described by psychiatrist Ann Wolbert Burgess and sociologist Lynda Lytle Holmstrom in 1974.

RTS is a cluster of psychological and physical signs, symptoms and reactions common to most rape victims immediately following and for months or years after a rape. While most research into RTS has focused on female victims, sexually abused males (whether by male or female perpetrators) also exhibit RTS symptoms. RTS paved the way for consideration of complex post-traumatic stress disorder, which can more accurately describe the consequences of serious, protracted trauma than posttraumatic stress disorder alone. The symptoms of RTS and post-traumatic stress syndrome overlap. As might be expected, a person who has been raped will generally experience high levels of distress immediately afterward. These feelings may subside over time for some people; however, individually each syndrome can have long devastating effects on rape victims and some victims will continue to experience some form of psychological distress for months or years. It has also been found that rape survivors are at high risk for developing substance use disorders, major depression, generalized anxiety disorder, obsessive-compulsive disorder, and eating disorders.

RTS identifies three stages of psychological trauma a rape survivor goes through: the acute stage, the outer adjustment stage, and the renormalization stage.
