After sex reassignment surgery, patients would live a happier life with a new satisfying vagina that can deliver the same sexual sensation as women’s.

A vagina is developed from a penis; its structure and nervous systems are indeed different from women’s. Commonly, sexual sensation depends on professional and techniques of a surgeon. A clitoris is a spot that is a center of se3xual sensation should be placed at the top of urethra. Patients may not have natural lubrication as well as women’s vagina so lubricant is needed.

Complication after Sex Reassignment Surgery 

Wound Split

At the lower part, a wound can be split which is can be treated with Betadine - Povidone-iodine for approximately a month in case of wound split.

Vaginal Contraction

After the surgery, a vagina will be 5-6 inch deep and after 4-6 months. The depth may increase for an inch in case that the vagina is too shallow. Additional surgery can be done 6 months afterwards, if needed.

Urinal Problems

It might happen after removal of urinary catheter or urethritis. The solution is to use a urinary catheter for 3-7 more days until the swollen is gone. 


On the first 3-5 days after a bandage removal, bleeding may occur, mixing with urine. If there is still bleeding, sanitary pads can be used to press the wounds. Commonly, the bleeding would eventually stop.
