When you hear the term 'female yeast infection' it is most likely referring to the vaginal type. men can both get yeast infections of the skin, the mouth, etc, but it's pretty safe to assert that a vaginal infection is precisely a woman's issue!
This kind of illness occurs for the same reasons that all yeast infections do; because of an overgrowth of Candida albicans in the body, sometimes called yeast. We all have yeast in our bodies, but things like a weakened immune mechanism may cause the yeast to grow out of control, thus resulting in the yeast overgrowth. For the yeast to grow and prosper it must be in the ideal environment, which is warm and moist which explains why the nads are such a standard spot for them. Couple that with a few other triggers like sweat or moisture from wearing damp clothing and you have the a recipe for yeast overgrowth.
Some techniques to elude getting this disease are to eat a healthy diet and try to keep healthy overall in order to keep your immune system nice and strong. Keeping your body clean and dry will also make a big difference. Also, taking an acidophilus supplement or eating yogurt with active cultures has also been shown to help forestall infections because this provides you with the 'good bacteria' that you need to battle off yeast internally.
A tiny information and diligence will go a good way in helping you keep those evil infections away, and when you do feel that familiar itch and pain, there are all sorts of remedies available-over the counter and natural-to help you fast so that you can get on with things.
