90 million women and girls are missing in China and India as a result of infanticide. Sex-selective abortion involves terminating a pregnancy based upon the predicted sex of the baby. The abortion of female fetuses is most common in areas where a culture values male children over females, such as parts of East Asia and South Asia (China, India, Korea), the Caucasus (Azerbaijan, Armenia and Georgia), and Western Balkans (Albania, Macedonia, Montenegro, Kosovo). One reason for this preference is that males are seen as generating more income than females. The trend has grown steadily over the previous decade, and may result in a future shortage of women. Forced sterilization and forced abortion are also forms of gender-based violence. Forced sterilization was practiced during the first half of the 20th century by many Western countries and there are reports of this practice being currently employed in some countries, such as Uzbekistan and China. In China, the one child policy interacting with the low status of women has been deemed responsible for many abuses, such as female infanticide, sex-selective abortion, abandonment of baby girls, forced abortion, and forced sterilization. In India the custom of dowry is strongly related to female infanticide, sex-selective abortion, abandonment and mistreatment of girls. Such practices are especially present in the northwestern part of the country: Jammu and Kashmir, Haryana, Punjab, Uttarakhand and Delhi.

Female genital mutilation Female genital mutilation is defined by the World Health Organization (WHO) as "all procedures that involve partial or total removal of the external female genitalia, or other injury to the female genital organs for non-medical reasons". The WHO further states that, "the procedure has no health benefits for girls and women" and "can cause severe bleeding and problems urinating, and later cysts, infections, infertility as well as complications in childbirth increased risk of newborn death". It "is recognized internationally as a violation of the human rights of girls and women" and "constitutes an extreme form of discrimination against women". The European Parliament stated in a resolution that the practice "clearly goes against the European founding value of equality between women and men and maintains traditional values according to which women are seen as the objects and properties of men".
