Is there any mediciene to stop pre cum leakage?is there any mediciene to to stop smell from balls:

See doctor: Keeping yourself clean may well help physical odors. Any ongoing discharge from your penis needs investigation. Please see your physician about this, in case it's more than "pre cum." be well, and be safe.

Normal Men: Nope. Absolutely not. Why would you want to interfere in any way with the normal function of your penis and sexuality? Please do nothing to change this or damage your prostate or testicle.

No and body spray: No meds to stop the pre-ejaculate that can occur, and you need to continue to bathe, use body washes, sprays, keep dry and treat any fungus you may have on your scrotal area/testicles to decrease any "smelly balls.".

Kinda sorta & Yes: While there aren't medications to stop pre-cum leakage per se, some medications are used off-label to prevent premature ejaculation (which may kinda sorta decrease pre-cum leakage). As for decreasing scrotal odor, just keep your genitals dry. Baby powder does just fine. If that isn't enough, then you need to see your doc to determine bacterial vs fungal cause in order obtain proper treatment.
