To help prevent yeast infections, it is essential to practise good hygiene in the genital area, which includes keeping the area clean and dry, wearing clean and breathable underwear, and avoiding the use of harsh soaps or other products that could disturb the skin. It is unlikely that using an intimate wash designed for men would directly cause a yeast infection. However, some men’s sac wash products may contain ingredients that could irritate the sensitive skin in the genital area, which could potentially lead to an increased risk of developing a yeast infection. Having said this, a male yeast infection treatment is always at hand if one develops it.
