Other than aesthetics, what are the the benefits of "Scrotox"?

The original use of Botox in the scrotum was to control perspiration. That’s the only non-aesthetic benefit. Aesthetic benefits include smoothing out the skin and lowering the testicles. I hope this helps.

The aesthetic benefits that arise from using Botox in the scrotal area are incidental. We began using Botox in that area simply to control sweating. In addition to reducing sweat, however, it was found that Botox smoothed the skin out, the testicles dropped and the testicles looked larger. Please consult a board-certified dermatologist who is an expert injector if you are considering “Scrotox”; this is an advanced use of Botox that must be entrusted only to a highly skilled professional.

Botox in the scrotal area is generally used purely for cosmetic reasons.  However, it can be used to treat excessive sweating in that area as well.

Botox is used in the groin area to reduce sweating. Not many people know that's how the whole Scrotox idea came about - as it was noticed the scrotums looked smoother in patients treated with Botox in the area. As the scrotum smooths out, it descends and can look a little bigger in some men. I guess this suggest "bigger junk" down there....Best wishes, Dr. ALDO 

Injection of Botox into the scrotum makes the scrotum appear smoother, makes the testes appear somewhat larger and decreases the sweating in the area
