Left-sided ovarian cysts can also lead to pregnancy. As long as the ovaries are functioning normally and there is normal ovulation, pregnancy is possible. For left ovarian cysts, it is important to find out whether they are pathological or physiological cysts. Physiological cysts often do not need to be treated, while pathological cysts need to be ruled out as malignant first, for example, laboratory tests for gynecologic tumor markers are needed, and if there are no abnormalities, the need for surgery for treatment will be decided based on the specific clinical situation. If it is treated conservatively, it should be reviewed regularly. If you want to plan a pregnancy, it is recommended to have a health checkup and to do the appropriate laboratory tests, such as sex hormone six, thyroid function, routine leucorrhea, liver and kidney function, etc. If there is no problem, you can consider pregnancy if you have a simple left ovarian cyst.
