Dr. Herazy,

Thank you for your time a moment ago when we spoke on the phone. If I may impose upon you for one last question: How long between application of DMSO to the shaft of the penis and sexual engagement should there be to avoid "sharing" the DMSO with your partner? Or, is this not something that one needs to be concerned with due to the benign nature of the substance?

Thanks,

Foster

Greetings Foster,

If you read on PDI website about DMSO you will learn that about 7-8 minutes after application for Peyronies disease treatment all DMSO is essentially gone from the surface of the skin and is being chemically taken deeper into the tissue; actually most is gone in 5 minutes or so.  Nonetheless, I suggest washing the shaft prior to intercourse because the penis shaft is covered with common skin as is the majority of the body, but inside the vagina is found a mucus membrane layer of tissue, similar to the inside of mouth or sinus passages.  This thin and delicate tissue might respond differently than the rest of the body – better safe than sorry.   TRH
