A 25 years old male is not happy with its gender and is always in distress due to this. He wants to change sex and have a vagina. It comes under which of the following psychiatric disorders?

Ans-AExpl- The International Classification of Diseases (ICD-10) list several disorders related to gender identity:Transsexualism (F64.0): Desire to live and be accepted as a member of the opposite sex, usually accompanied by a desire for surgery and hormonal treatmentGender identity disorder of childhood (F64.2): Persistent and intense distress about one's assigned gender, manifested prior to pubertyOther gender identity disorders (F64.8)Gender identity disorder, unspecified (F64.9)Sexual maturation disorder (F66.0): Uncertainty about one's gender identity or sexual orientation, causing anxiety or distressSignificant revision of the ICD's classification of gender-identity-related conditions is expected in the forthcoming ICD-11. As of August 2018, the ICD-11 lists this condition as "gender incongruence", under "conditions related to sexual health", coded into three conditions:Gender incongruence of adolescence or adulthood (HA60): replaces F64.0Gender incongruence of childhood (HA61): replaces F64.2Gender incongruence, unspecified (HA6Z): replaces F64.9In addition, sexual maturation disorder has been removed, along with dual-role transvestism. ICD-11 defines gender incongruence as "a marked and persistent incongruence between an individual's experienced gender and the assigned sex", with presentations similar to the DSM-V definition, but does not require significant distress or impairment.
