Physical response to sexual violence
        Effects and aftermath of rape can include both physical trauma and psychological trauma. However, physical force is not necessarily used in rape, and physical injuries are not always a consequence. Deaths associated with rape are known to occur, though the prevalence of fatalities varies considerably across the world. For rape victims the more common consequences of sexual violence are those related to reproductive health, mental health, and social wellbeing.
        Gynecological
        Common physical injuries received by rape victims include: Vaginal bleeding or infection, fibroids, decreased sexual desire, genital irritation, pain during intercourse, chronic pelvic pain, urinary infections.
        Pregnancy
        Pregnancy may result from rape. The rate varies between settings and depends particularly on the extent to which non-barrier contraceptives are being used. A study of adolescents in Ethiopia found that among those who reported being raped, 17% became pregnant after the rape, a figure which is similar to the 15-18% reported by rape crisis centres in Mexico.
        A longitudinal study in the United States of over 4000 women followed for 3 years found that the national rape related pregnancy rate was 5.0% per rape among victims aged 12-45 years, producing over 32 000 pregnancies nationally among women from rape each year.
        Experience of coerced sex at an early age reduces a woman's ability to see her sexuality as something over which she has control. As a result, it is less likely that an adolescent girl who has been forced into sex will use condoms or other forms of contraception, increasing the likelihood of her becoming pregnant.
A study of factors associated with teenage pregnancy in Cape Town, South Africa, found that forced sexual initiation was the third most strongly related factor, after frequency of intercourse and use of modern contraceptives. Forced sex can also result in unintended pregnancy among adult women. In India, a study of married men revealed that men who admitted forcing sex on their wives were 2.6 times more likely to have caused an unintended pregnancy than those who did not admit to such behavior. Should pregnancy result from a first-time encounter it would carry a higher risk of pre-eclampsia, the condition in which the mother's body reacts adversely to the proteins of the fetus.
        Sexually Transmitted Diseases
        Violent or forced sex can increase the risk of transmitting HIV. In forced vaginal penetration, abrasions and cuts commonly occur, thus facilitating the entry of the virus through the vaginal mucosa. Adolescent girls are particularly susceptible to HIV infection through forced sex, and even through unforced sex, because their vaginal mucous membranes have not yet acquired cellular density sufficient to provide an effective barrier that develops in the later teenage years.
        Being a victim of sexual violence and being susceptible to HIV share a number of risk behaviors. Forced sex in childhood or adolescence, for instance, increases the likelihood of engaging in unprotected sex, having multiple partners, participating in sex work, and substance abuse. People who experience forced sex in intimate relationships often find it difficult to negotiate condom use either because using a condom could be interpreted as mistrust of their partners or as an admission of promiscuity, or else because they fear experiencing violence from their partners. Sexual coercion among adolescents and adults is also associated with low self-esteem and depression factors that are associated with many of the risk behaviors for HIV infection.
        Research on women in shelters has shown that women who experience both sexual and physical abuse from intimate partners are significantly more likely to have had sexually transmitted diseases.
