Complications of Penile Self-injections: Investigation of 680 Patients with Complications Following Penile Self-injections with Mineral Oil

Objective: Penile implants and injection of foreign materials have been described in texts like Kama Sutra for more than 1500 years, and are still being practiced around the world. The extent of this practice is unknown, and the documentation available today only scratches the surface. This study investigates and documents the complications after penile self-injections at the Mae Tao Clinic. To our knowledge, this study represents the largest series of patients representing complications to penile self-injections.

Study Design: Retrospective study.

Methods: We investigated data on 680 patients admitted with penile self-injections during a 5-year period. Data were studied for general patient data, symptoms, time of injection, and treatment.

Results: Age at admittance ranged from 17 to 68 with a mean age of 32 years. Time between injection and presentation was registered with a mean of 36.7 months, over half presented with complications within 1 year. Most frequent complications were penile pain (84%), swelling (82.5%), induration (42.9%), purulent secretion (21.8%), and ulceration (12.8%). Of the 680 patients, 507 (74.6%) underwent surgical treatment (503 excision and 4 circumcision), while 173 (25.4%) were treated conservatively.

Conclusion: Our data suggest that penile self-injections with mineral oil are more prevalent in certain areas than previously acknowledged. In 5 years, more than 680 patients presented with complications to penile self-injections, of which 75% needed surgical intervention, mainly in the form of radical excision of the lesions followed by skin grafting. Preventive measures to this physically and psychologically devastating problem are highly warranted.
