The most common endocrine manifestation of GCTs in postmenopausal women is abnormal uterine bleeding. This is caused by resumption of endometrial proliferation due to estrogen production by the tumor. For this reason, endometrial hyperplasia and/or endometrial adenocarcinoma may be a concomitant finding in women with GCT.

Patients also can have breast tenderness and increased vaginal secretions from estrogenic stimulation of the breast and vaginal tissues, respectively.

Rarely, a patient may present with virilizing symptoms such as acne, hirsutism, deepening of the voice, and clitoral enlargement. This is due to testosterone and/or androstenedione production in a minority of these tumors.
