What can I do to kill the bacteria that's causing foul body odor in my groin area .I'm a guy?

Maybe you have a fungal infection if the area is itchy and go buy some antifungal cream from the pharmacy and use as directed until the fungal infection is killed off. Signs of a fungal infection or Jock itch as it is commonly known is the area is itchy a lot, and tends to feel a bit moist even slimy. Fungal infections love damp sweaty moist areas of the body such as between your toes and around your groin. Hopefully that is your problem, but if it isn't then it is a trip to a doctor to see if he can find what is causing this. Hand soap is one of the best killers of bacteria in the world as apparently if causes the outer membrane of bacteria to rupture and kills the bacteria, but more likely a fungal infection is your problem.

This question has been asked and answered like 100s of times, look it up and see what's been answered, it's not going to be something different or new than what's been said before.

try a couple of things-- soak the area with peroxide for a few minutes, regular pharmacy grade peroxide you can buy for $1 or so. Peroxide kills bacteria. Be sure and do it in the tub or shower to avoid a mess, and then rinse off after a few minutes. But often a really foul odor is caused by fungal infection--so a jock itch medication is called for to get rid of that.

As others have stated regular bathing with soap and water is the first step. If the problem continues try applying baking soda around the groin region.Baking soda is safe and absorbs odors. You can also try applying apple cider vinegar which is good for the skin and is a natural antiseptic. If the problem persists see a doctor.

use a good quality mouth wash.... it will help enormously...

If it's that bad and frequent bathing doesn't help, you need to see a doctor.

wash often, use talc, change underwear daily and remember to clean under your foreskin

The question s not clear.Ut may be due to accumulation of sweat around groin area and pubic area Why not shave off the pubic hairs and apply some talcum powder.Sometomes it will clear the bad odour ..If not cleared please consult your family physician who will be a better guide.Regards.

"Athletes Foot" talc, plus using an anti-dandruff shampoo as body wash.

Between the two they kill many common scing bugs and fungi.

And use antiperspirant on your crotch as well as under your arms...

You should ask a doctor what you can do
