Leukorrhea is a secretion from the vagina and cervix of women. Under normal circumstances, leukorrhea is milky white and clear and has no odor. However, if a woman’s leucorrhea is tofu-like, it is a pathological change, caused mainly by mycosis fungoides infection. Mycosis fungoides is a common inflammatory disease of the female vagina, mainly caused by Candida albicans, also known as mold infection. Candida albicans is ubiquitous in our daily life, if women’s own body resistance and immunity is reduced, Candida will invade the skin tissue and cause a series of lesions, invading the vaginal skin will cause mycosis vaginalis. When Candida invades the vaginal skin, it irritates the vaginal mucosa, resulting in increased vaginal discharge and tofu-like discharge, accompanied by intense vulvar itching, odor, and a series of other clinical symptoms. The infection of mycosis vaginalis is related to various factors such as unclean sex, lack of good personal hygiene and damp and airless underwear. The chance of having sex with a man with Candida infection can reach more than 90 percent, but men do not have any obvious symptoms after Candida infection due to their special physiological structure. You should pay more attention to personal hygiene, underwear, household items need to be disinfected with the sun, try to keep the pubic area dry and fresh, do not share household utensils with others.
