The right surgeon FOR YOU is the most important decision. IP or PS is probably lower on the list. You want a high volume doctor with a history of great results. According to Perito, there is no difference between the 2 options after the recovery period.
However, during my research phase I determined that there were a few things that led me to seek an PS approach. Keep in mind, I'm just a guy reading studies, opinions, reviews, statements, etc. This is MY interpretation, others feel the exact opposite.
-A study has shown that the size of the implant is larger when installed penoscrotally. Not much, but larger nonetheless. Seems that access to the corpora for measuring and inflating is better with the PS approach. Watch some youtube videos of both and you might notice the difference,
- Installation of the pump is much more easily done when implanting it directly in the scrotum, which is accomplished by penoscrotal surgery. The doctor can place it exactly where he would like it to live, and you and your partner will appreciate the best placement possible.
- Infrapubic involves a higher risk of damaging the nerves in your penis. The nerve bundle is on the top of the penis and must be manipulated to some degree during the IP surgery. The risk seems to be small, but it is a factor worth being aware of.
-Installation of the reservoir is more difficult when installed through the scrotum, this is a clear advantage of infrapubic installation. My thought process was that I will have interaction on a daily basis with the pump, and I want it placed perfectly in my sac. Hopefully I'll never know or care about the reservoir, and sure enough...I was never sore and I would have no idea where it is in my abdomen had the doctor not pointed to the side it's on.
-Infrapubic will often result in a much quicker release to cycle and use your new penis as intended. Since pumping the cylinders is not stretching out or affecting an incision in your scrotum, men who had IP are often released to start messing around with stuff in days or a couple of weeks. Penoscrotal implantees are usually told to wait 4-6 weeks before cycling or sex. For me, a week here or there to get started didn't outweigh the other advantages I felt penoscrotal offered.
-2 very prolific doctors 100% disagree on which option is best. Eid says that IP is a bad idea and is vocal about it being a mistake, he recommends PS. Perito swears by infrapubic and trains others on how to do them. My PERSONAL opinion is that Perito's preference for IP is tied to the speed at which he can perform the surgery (he claims 15-20 minutes), which in turn allows him to do 4x the ca$e$ as compared to a doctor doing PS and taking about an hour per case (without complications).
-my wife and I enjoy nude resorts now and again, and I didn't want a visible scar showing above my penis. I'm sure it would fade with time, but I don't need all the other guys knowing I'm a cheater..
-of course, if you've had previous surgeries down there or hernia issues, your doctor will know best which option is better for you.
The most important decision is the doctor. In my case, I had a penoscrotal incision and during the measuring phase Dr. Clavell was unable to get the dilator up into my glans on the left side of my penis. He tried smaller dilators but was unable to break through some scar tissue nobody knew was there. On the fly, Dr. Clavell made an incision in my shaft and removed the scar tissue in the corpora and was able to place both cylinders perfectly up into my glans. After the surgery I found a paper that Dr. Clavell was associated with that helped pioneer the very correction I needed. I don't think that had anything to do with PS vs IP access to the glans of my penis, but I'm certain a lesser experienced doctor would not have been ready, able or equipped to perform that additional uncommon surgical correction.
The doctor you choose is the most important factor by a mile.
