In the past, when we talked about sexually transmitted diseases (STDs), the first thing that came to mind was men. Indeed, according to the statistics of 8 years ago, the incidence of patients are mainly male, the ratio of male to female is 8:1. However, in recent years, the number of female patients with sexually transmitted diseases has risen faster, and now the ratio of male to female patients with sexually transmitted diseases has reached 1.4:1. Moreover, many sexually transmitted diseases that are obvious in men often have no special manifestations in female patients, which leads to a delay in the time of treatment. Untreated STDs in women can lead to pelvic inflammatory disease (PID), causing difficulty in sexual intercourse and pain in the lower abdomen and back; they can go up to the fallopian tubes to cause salpingitis, leading to infertility and ectopic pregnancy; some viruses, such as human papillomavirus (HPV) and human herpes simplex virus (HSPV), are associated with the onset of tumors of the reproductive system, such as cervical, vulvar, and anal cancer, among others. Infection of a pregnant woman with an STD can also lead to miscarriage, intrauterine fetal death, preterm labor, or infection of the newborn during delivery. Wouldn’t it be too late to treat STDs if it came to this? So, is there any way to recognize that a woman may have an STD through certain signs? The following six conditions are quite characteristic, once found these signs, can be highly suspicious of women have contracted STDs, women and sexual partners can learn to timely treatment and self-protection. 1, leukorrhea increase: yellow or green pus, often accompanied by pain when urinating, urinating more often, and there is a situation that can’t urinate. 2, leukorrhea increase: for tofu dregs-like, white, lumps, the amount of obvious increase.
