Whoever said there were no risks were mistaken or misinterpreted. This procedure carries basic risks found universally in all medical facilities... the risk of bacterial infection due to negligence (i.e. lack of sterilization)... although these risks are greatly minimized by medical staff, even the finest clinics and hospitals deal with freak incidents. This particular risk is an obvious (and minimal) one, but it should be noted.
Complications as a direct result of PMMA have been attributed more to poor technique and/or poor grade of PMMA versus an actual adverse reaction to PMMA. While there is still debate on the matter, the only complications known to have arisen from PMMA injections have been limited to granulomas (a tissue growth induced by an inflammatory response). Conceivable complications like migration or rejection have not been reported with the use of medical grade PMMA in Dr. C's practice.
Relatively speaking, in the short term PMMA has a remarkable safety record. I believe Smartman is our longest reporting PMMA-Penis member at 3 years, and GSXR is our longest reporting Dr. C patient at 7 months (correct me if I'm mistaken). Evil Pneivel did appear to have some type of nodule formation (although was never diagnosed as a granuloma) which was painless and benign. This was resolved with kenalog injections which he details here http://phalloboards.websitetoolbox.com/post?id=5360270
. I believe we had another member (will look to find his name from the old board) who had some sort of fluid build up (edema-like) in his shaft that eventually subsided. Outside of these significant reports, no other major complications have been reported from forum members.
It's also important to note that Artefill, an FDA approved brand of PMMA for use in the U.S. has shown no sign of migration, injection, or rejection.
There is a good convo going on in the primary PMMA thread regarding the relevance of PMMA brands and their respective "qualities," and how that could potentially increase the chance for complication. Dr. Casavantes uses New Plastic, and some contend this product is not as "pure" as the American-approved Artefill.
I personally think Dr. Casavantes has established a portfolio and reputation that deserves consideration with respect to the brand of PMMA being used. He has been working with PMMA for a while and has his trust behind the New Plastic product. It is his faith in the product that reinforces my faith in the product. Simple as that.
As for my feelings on the risks with PMMA... I buy the (obviously plausible) scenario that most complications have arisen from poor technique and/or poor grade of PMMA.
I believe Artefill's high cost coupled with the complexity of masterful injection technique (especially in an organ as dynamic as the penis) makes this procedure uncommon, at least as far as the U.S. is concerned. It is, however, commonly practiced in Mexico and South America and in my belief, will eventually trend in the states when the prices are brought down and there is an increase in qualified injectors.
If I had to note any noticeable issue that required some attention it would be a non-visible ring of slightly palpable bumps that make a semi-circle just outside the base of my shaft. I believe these to be scar tissue spots from the entry points used, and was told that they will lessen in time. I was also told injections can help reduce them if they persist. These bumps are hardly noticeable yet palpable but you have to really inspect them closely, and they don't seem to cause any pain to the touch.
I do have a minor aesthetic issue where there is little to no PMMA between the glans and the upper part of my shaft, but I don't consider this a negative because it was to be expected (the doctor recommends 2 rounds because contour issues are almost inevitable given the unpredictability of PMMA's settlement after the first round).
Otherwise, there was virtually no pain after the procedure, just mild tenderness. There has been no pain since, nor any major change in sensitivity (although if I were to consider pre-op at 100% sensitivity, I did dip to 95% before returning to 100%...which may be explained by the creation of new nerves ?? ). The function of the penis is unchanged and the erections are remarkably firmer (it seems the collagen is slightly tougher than the pre-pmma tissue).
All in all, keep in mind anything phalloplasty possesses risks, but in my opinion, this one possesses the least of all the semi-permanent and permanent options available. Be sure your decision to entertain the idea of penis enlargement via medical intervention is a sound, healthy, and rational one. I'm not judging those who choose to get it for sheer vanity, but I express caution. Otherwise, those who are undersized or wish to enhance sex for their significant others are the best candidates in my humble opinion.
