Endometriosis is a common gynecological disease that severely troubles women's daily lives. Besides causing painful menstruation, endometriosis is also a common cause of infertility. The reasons for infertility caused by endometriosis include the following aspects:

First, endometriosis often leads to the formation of chocolate cysts on the ovaries, which can affect ovarian function and cause impaired ovarian function.

Second, endometriosis can sometimes affect the function of the fallopian tubes, causing adhesions in the fallopian tubes. This may result in difficulties in egg pickup, preventing the sperm and egg from meeting and forming a fertilized egg in the fallopian tubes, leading to infertility.
