Introduction: Female feticide is the process of finding out the sex of the fetus and undergoing abortion if it is a girl. This is one of the most prevalent issues today. The preference for the male child dates back into history and obviously, therefore, female feticide has long been practiced in Indian societies. With the advancement in technology and development of easier and cheaper techniques, female feticide has spread throughout India. The government has amended the Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) Act of 1994 that criminalized prenatal sex screening and female feticide, making it illegal in India to determine or disclose the sex of fetus to anyone.
