Do condoms prevent yeast infections?
Yeast infections aren't normally contagious, and their occurrence isn't reduced by using condoms.
Yeast infections can be caused by not changing underwear, tampons, or pads, so always make sure to change them regularly. Another way to prevent yeast infections, this method is sort of controversial, is to eat yogurt regularly, there is limited research that yogurt prevents yeast infections, but it is definitely worth a try.
I dont know of any connection between L-argentine and yeast infections. Yeast infections are usually caused by irritation or sexually transmitted back and forth between partners, or if you are using condoms with nonoxynol-9, they are know to cause yeast infections, so try using a condom that doesn't have a spermicidal lubricant.
Yeast infections can be treated with fluconazole. To enhance healing you should know what triggers your yeast infection and try avoiding them. For example, most women got their yeast infections from poor hygiene. To prevent reoccurence, try improving your hygiene and take medications such as fluconazole.
No, yoghurt cannot give you a yeast infection - at least not unless you put yoghurt sweetened with sugar into your vagina. Yoghurt can help prevent and treat yeast infections, the bacteria found in probiotic yoghurt is the same found in healthy vaginas so eating it can help maintain healthy bacteria within the body. You can insert sugar-free plain probiotic yoghurt vaginally to reintroduce healthy bacteria to prevent infections or to treat yeast infections.
