Gender reassignment surgery is also known as a sex change, genital reconstruction surgery or sex affirmation surgery. It is performed to change genital organs from one gender to another. Surgery may be required on a newborn baby with intersex deformities Or it may be because someone chooses to be surgically altered. It is surgically easier to convert to a female rather than male. Newborns with intersex deformities will usually be assigned to the female gender. Male to female surgery involves removing the penis and reshaping the genital tissue to construct a vagina.Female to male surgery is more difficult due to the need to achieve a functioning penis from the smaller female genitals and penis construction is usually not attempted less than a year after removing the female organs. Breasts are also changed to a more male appearance.
