Yes, a woman with a teratoma (dermoid cyst) in the ovary can take contraceptives. However, unlike other types of ovarian cysts, the use of the contraceptive pill do not make the teratoma regress and therefore it is not used in its treatment, which is exclusively surgical.
also there is no evidence that taking contraceptives can lead to the development of teratomas in the ovary.
The use of hormonal contraceptive is always allowed, without restrictions, risks or contraindications, in cases of benign tumors of the ovary, of which the teratoma is part.
Even in cases of malignant teratomas (ovarian cancer), the woman can take contraceptive, provided that she has a rigorous medical monitoring.
However, whenever a woman has a health problem involving her reproductive system, it is up to the gynecologist evaluate the case and decide whether to continue contraceptive use or not.
