Sex reassignment surgery is usually preceded by beginning hormone treatment with testosterone.Many trans men seek bilateral mastectomy, also called "top surgery", the removal of the breasts and the shaping of a male contoured chest.
This technique results in far less scarring, and the nipple-areola doesn't need to be removed and grafted.If the cervix is removed, it is called a 'total hysterectomy.' Some trans men desire to have a hysterectomy/BSO because of a discomfort with having internal female reproductive organs despite the fact that menses usually cease with hormonal therapy.Completely removing and grafting often results in a loss of sensation of that area that may take months to over a year to return, or may never return at all; and in rare cases in the complete loss of this tissue.In these rare cases, a nipple can be reconstructed as it is for surgical candidates whose nipples are removed as part of treatment for breast cancer.
In addition, there is less denervation (damage to the nerves supplying the skin) of the chest wall with a peri-areolar mastectomy, and less time is required for sensation to return. Hysterectomy without BSO in women is sometimes erroneously referred to as a 'partial hysterectomy' and is done to treat uterine disease while maintaining the female hormonal milieu until natural menopause occurs.A 'partial hysterectomy' is actually when the uterus is removed, but the cervix is left intact.
