UroToday.com – Erectile dysfunction is the most commonly recognized side effect of radical prostatectomy (RP) for prostate cancer (CaP). However, post-surgery penile length shortening (PLS) is known to occur in up to three-fourths of men. The impact of PLS has not previously been assessed.

The mechanism causing PLS is not known, but may be related to anatomic changes or fibrosis and scaring in the retropubic space. Studies suggest that men are more concerned with penile length than women, and that men desiring penile lengthening actually have normal penile length. The goal of this study that appears in the more…

Biological Psychiatry

, suggests that it has something to do with the way that we control the activity of the prefrontal cortex, a brain region thought to orchestrate our thoughts and actions.

Researchers at the Mount Sinai School of Medicine examined women who had been the victims of violent sexual assault, some of whom developed PTSD and others who did not develop any serious emotional symptoms afterwards.

Two hundred used the PSD502 spray, which contains 7.5mg of lidocaine and 2.5mg of prilocaine, and 100 used a placebo spray with no active ingredients.

UroToday.com – The concept behind nerve grafting is to make use of one’s own nerves, which play a minimal functional role, as conduits to promote the regrowth of new nerve fibers. In certain patients with prostate cancer, the nerves crucial for erectile function (cavernous nerves) may need to be cut in the interest of removing high-risk cancer. In these situations, the genitofemoral nerve can be interposed (grafted) as a conduit to promote regrowth of new nerve fibers. Our study examined the feasibility and success of this in patients with prostate cancer as well as those with bladder cancer, in which the prostate is also removed.
