Unilateral chocolate cysts may also lead to natural conception clinically because one ovarian chocolate cyst, with normal ovarian tissue on the other side, can still secrete estrogen and progesterone periodically and still ovulate, so there is a chance of natural conception. It is advisable to monitor ovulation by ultrasound and to have intercourse when the ovary on the healthy side is ovulating, which will increase the chance of pregnancy. In addition, clinically, ovarian chocolate cysts are a clinical manifestation of endometriosis. It is likely that about 30-40% of patients will experience infertility, so if a chocolate cyst is found and there is no natural conception, surgery may be considered for treatment. After surgery, due to the high rate of recurrence, it is recommended that treatment with Daphylline be available for about three months to six months.
