Introduction:
Fifty-two-year-old male with history of multiple insults to his erectile tissue, including insertion and removal of penile implant, presents with significant partial erectile function, substantial enough for anal penetration during sexual intercourse.
Aim:
Erectile function rigid enough for anal penetration, let alone any erectile function after removal of an inflatable penile prosthesis (IPP), is rare. This article, to our knowledge, is the first case of a patient who has undergone multiple insults to his erectile tissue, including an episode of ischemic priapism followed by implantation and removal of an IPP, who presents with erectile function sufficient enough for coitus.
Main Outcome Measures:
Outcome measured via standardized patient questionnaires and penile Doppler following injection of Trimix.
Method:
An objective measure of the patient's erectile function was performed via penile Doppler.
Results:
Penile Doppler after 10-mcg injection of Trimix revealed numerous perforating vessels from the corpora spongiosum providing blood flow to the corpora cavernosa. The patient obtained approximately 60-70% rigid erection.
Conclusions:
To our knowledge, and after thorough review of the literature, we could not find any reports of erectile function significant enough to take part in sexual intercourse and penetration after removal of a three-piece IPP. The implant usually disrupts the normal anatomy which allows for cavernosal arterial vasodilation and increased blood flow into the corpora. Following dilation of the corpora the cylinders are inserted and inflated, and the smooth muscle that makes up the corpora cavernosum is compressed against the wall of the tunica albuginea. Theoretically, the remaining smooth muscle tissue may retain some of its physiologic function, adding some additional girth to the penis with an already activated IPP during sexual intercourse.

Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...
