Hello, Do not concern. Endometriosis affects fertility by inducing scar tissue formation that compromises the function of fallopian tubes. It can also prevent fertilization when endometriosis cells secrete substances that might obstruct the interaction of the sperm and the egg. In addition, there are other hormonal dysfunctions that come along with this condition that can cause weak implantation leading to early miscarriages. If you have been diagnosed with an ovarian cyst and are concerned about becoming pregnant, talk to your doctor. Surgical procedures, such as laparoscopy or laparotomy, can also be performed to eradicate this type of problem Take care.
