SRS Female to Male
Sometimes when newborns are found with intersex deformities, they must be early assigned to one sex or the other. These deformities represent intermediate stages between the primordial female genitals and the change into male genitals caused by male hormone stimulation. In some cases both men and women occasionally believe they are physically a different sex than they are mentally and emotionally. This is called gender dysphoria or gender identity disorder.
In both cases, technical considerations favor successful conversion from one sex to the other in order to better define the external sex organs. Sexual Reassignment Surgery (SRS) alters the physical appearance of a person from one gender to another. The phalloplasty operation which is the gender change operation from female to male is the most demanding and difficult operation in the field of Transexuality.
However, female to male surgery has difficulty of creating a functioning penis from the much smaller clitoral tissue available in the female genitals. Penis construction is not attempted less than a year after the preliminary surgery to remove the female organs. However, most patients were pleased with the change of sex. Besides the genital organs, the breasts need to be surgically altered for a more male appearance. This can be successfully accomplished.
The capacity to experience an orgasm, or at least "a reasonable degree of erogenous sensitivity," can also be expected by almost all persons after gender reassignment surgery.
