The gynecological diseases bring many hazards to women’s bodies, not only the discomfort caused by the disease itself, but also the adverse consequences caused to women’s bodies, such as certain gynecological diseases that can affect fertility. 1, pelvic inflammatory disease: pelvic inflammatory disease occurs after the infertility caused by a number of factors, the pathogenesis is also quite complex. Firstly, inflammation destroys ovarian function, disrupts hormone secretion, affects ovulation, follicles do not develop normally or rupture and leads to infertility. 2, vaginitis: after the onset of vaginitis, on the one hand, the change in the pH of the vaginal environment will affect the motility of the sperm entering the vagina; on the other hand, because trichomonas engulfs the sperm, it can hinder the production of lactic acid; also, there is a large increase in purulent secretions in the vagina, and the secretions contain a large number of white blood cells, all of which will hinder the viability of sperm and reduce the number of sperm. In addition, painful intercourse and decreased libido when inflammation occurs can affect pregnancy. 3, endometritis: endometrial inflammation occurs, local inflammatory cell infiltration and exudation of inflammatory mediators present embryotoxic effects, which is not conducive to sperm survival and pregnancy egg implantation, inflammation involving the fallopian tubes can cause obstructive infertility. In addition, endometritis can affect endometrial regeneration, repair and normal contraction. As a result, the patient’s fertility environment is like a poor ridge of land that makes it difficult for seeds to germinate and grow, leading to infertility.
