Like injectable fillers, these platelet-rich plasma (PRP) treatments involve injections into your penis. First, you get a local and topical anesthetic to keep you comfortable. Then your doctor draws blood from your arm and spins it in a centrifuge to separate the red and white blood cells and concentrate the platelets, which are rich in growth factors. They then inject the platelets into several different areas of your penis.
A study published in 2019 that looked at various medical, traction, injection, prosthetic, and reconstructive procedures states that complications are “likely underreported.” The same study also says that the worst complications, although rare, can be “devastating.” These include penile fibrosis, sexual dysfunction, and even (in at least one case) death from pulmonary embolism. If you do decide to undergo a penis enlargement procedure, consider all the risks and follow all post-op instructions carefully.
Penis size is determined by hormone exposure and varies greatly from one individual to the next. The average length of a flaccid penis is between 3.4 and 3.7 inches, while the average length of an erect penis is between 5.1 and 5.7 inches. The average circumference of an erect penis is between 3.5 and 3.9 inches. Learn more about the average penis size.
