With wikipedia you always have to look at the references: womenshealthmag.com and africanseer.com for your quote but I think I’ve found the original here:
MP59-19 A Retrospective Evaluation of the Safety and Effectiveness of a Silicone Block Implant for Elective Cosmetic Surgery of the Pens presented at the Sexual Medicine Society of North America 21st Annual Meeting - Nov 2015 (abstract).
So this isn’t likely to be peer reviewed research. I don’t know the details for this organisation (you could probably find out) or what it requires of people giving talks. Often it’s simply a matter of paying money to the organisers. Unfortunately, this is the same tactic creationists use to add “scientific weight” to their arguments. There have been creationist papers presented at archaeology conferences specifically so they can be later cited by the same creationists.
Penis enlargement surgery is very much more experimental than breast enlargement surgery. So yeah, a lot of people here aren’t particularly interested, especially considering the other lower risk alternatives that work quite well for many people willing to put in some effort. Again, we are a forum, so we don’t know how many people fail to gain but there is definitely a proportion.
Do spend some time on phalloboards. As the name suggests it’s raison d’être is phalloplasty so you are likely to be getting opinions from people who’ve has various types of enlargement surgery done on them.
I agree with Thunder, if you go ahead, please consider documenting your experience and sharing it and then the next person who comes along will have more information than you.
