Testicular implants, aka testicular prostheses, synthetically replace one or both testes. Inserted inside the scrotum (the sac that holds the testicles), they don’t retain any of the functionality of real testes. The procedure is done primarily for cosmetic reasons. Â
Testicular implants can address concerns like asymmetrical or irregularly shaped or sized testicles, which can help boost self-esteem.Â
The surgery may also be performed after a man’s testes have been surgically removed during orchiectomy (to treat testicular cancer, for example), in cases where they are absent due to a birth defect or physical trauma (such as severe torsion, or twisting), or to treat advanced prostate cancer. It doesn't help with erectile dysfunction, which is better addressed with a penile implant.
For transgender men, testicle implants can be inserted after scrotoplasty, a gender confirmation procedure that creates a scrotum from labial tissue.
A company called Coloplast manufactures testicular implants under the brand name Torosa. This saline-filled testicular prosthesis, encapsulated in a silicone elastomer shell, is currently the only FDA-approved option on the market. (Most silicone gel-filled options have been discontinued by the FDA.)Â
These saline sacs are designed to look and feel as close to a normal testicle as possible. They come in a variety of different sizes, so your doctor can find the ideal implant to match your scrotum and proportions, giving it the most natural appearance possible.
