Wearing a contraceptive ring does not lead to infertility in women. Generally, after the ring is inserted, it can compress the endometrium, leading to aseptic inflammation of the endometrium. It can also cause small ulcers, affect the coagulation function of the uterine cavity, and the environment within the uterine cavity, making it difficult for the fertilized egg to implant, thus serving its contraceptive purpose. However, typically, if there is a desire for childbirth, removing the ring within three to seven days after the end of menstruation can restore normal reproductive functions. In very rare cases, after the removal of the ring, adhesions in the uterine cavity and damage to the basal layer of the endometrium can occur. This can indeed affect a woman's normal ability to conceive. In some cases, even if conception occurs, there might be complications such as missed miscarriage or threatened abortion.
