From the article:
I think that's a huge hCG dosage and IM to boot. This also was a study on guys with a micropenis (I didn't know such a term existed), but a 2 cm gain is something to consider. Definitely interesting!
In other news... not saying I'm long dong here, but I clear the averages well in terms of length and can attest that you start to have to be careful on how deep you go. There are women that like the length (my wife included), but punching a woman's cervix is usually not pleasant for them (although lightly touching can be). What you see in porn is a woman getting paid to have this happen... it's typically not what women in real life enjoy. If you are "average" length, then I wouldn't worry about getting longer.
That said, length does provide access to some fun positions
