I have been researching hard on this and thrush is seldom listed as a side effect but virginal dryness and itchiness is as for the menopause. Your vagina is usually acidic but take the Oestrogen away and it becomes more alkaline. The PH inside your vagina becomes more favourable to yeast infections. You need to do all the obvious things like wearing cotton pants, don't wear tight trousers so much, change and shower straight after exercise and don't sit around in a wet swimming costume. Further reading led me to find that inserting a vitamin E capsule into the vagina and rubbing vitamin E oil on the external skin will help with the dryness and will moisturise for sex. Using it once a day or just before sex will help but is not recommended for use with condoms as it dissolves them. Look on the Livestrong website for information.
