Ovary is an important sex organ of women, and ovarian cysts are common gynecological diseases. Ovarian cysts need to identify benign and malignant in clinic, some of them can be observed without treatment, and some of them need surgery, while most of the ovarian cysts have no effect on pregnancy. There are two types of ovarian cysts: physiologic and pathologic. Physiologic cysts have no effect on the human body, sometimes appearing and sometimes disappearing, so they have no effect on pregnancy. Pathological cysts are benign, malignant and junctional, among which benign tumors include ovarian plasma cystadenoma, mucous cystadenoma and endometriotic cysts, etc. When endometriotic cysts and tubal ovarian cysts occur, because they affect the peristalsis of the fallopian tube and the surrounding tissues are adhered to, the mobility of this kind of ovarian cysts is usually poorer, and this will affect pregnancy. Other kinds of benign tumors that do not affect the function of the ovaries will not affect pregnancy, but it is best to treat ovarian cysts before getting pregnant, so as not to jeopardize your health in case of malignant changes in ovarian cysts. Therefore, ovarian cysts do not necessarily affect pregnancy, but only if the cyst itself affects the function of the ovaries or the combination of egg and sperm.
