There are definitely risks, hence the infection warning at the end there. Mechanically speaking, it’s pretty simple… think of like a pump action squirt gun ‘super soaker’ or w/e from when you were a kid, except the end of the gun loops back into the tank it pulls from: so you push the mechanism to build up pressure, then pull the trigger to release that pressure.
Instead of pump it’s a button over a one way valve that’s on the reservoir that hangs out in your scrotum like a 3rd testicle. That’s filled with a few mL’s of saline, and when you press the button it squirts the saline into prosthetic balloons that match the shape of your corpora cavernosa - the two chambers that run the length of your shaft that normally fill with blood to enable fun times. Anyway, push the button until it’s hard, engage in fun times, then push another button that’s basically just another one way valve to release all the saline back into the reservoir. Everything is internal - you feel the buttons through the skin of your scrotum.
There are pictures (animated - nothing gory or anything… it does depict a penis and this is a sfw thread, so I won’t direct-post it here, but it’s about as sfw as a picture of a penis can be… high-school health class textbook type of image) in the link I posted down toward the bottom of the page if you’re curious.
I always thought it was kinda cool - we can restore a pretty significant part of someone’s life with just a couple balloons, tubes, and some saline, and it’s not like most prosthetics where we’re replacing something (i.e., total knee replacement uses a prosthetic femoral head and tibial plateau, but before we can place those, we break out a powered saw, and things like a hammer and chisel to cut out the original femoral head and tibial plateau… it’s gory as fuck). The penile prosthesis just kinda sits in space that the body already provides.
Was gonna say, every single one of the Goth kids I grew up around would have absolutely loved that.
