Androgen, estrogen and progestin binding in cytosols of benign gynecologic tumors and tumor-like lesions.

Specific androgen (Kd 0.27 +/- 0.06 nM), estrogen (Kd 0.19 +/- 0.04 nM) and progestin (Kd 0.22 +/- 0.07 nM) binding were investigated in benign gynecologic tumors and tumor-like lesions. The simultaneous presence of androgen and progestin receptors was a common finding. In one endometrioma, specific androgen, estrogen and progestin binding was observed simultaneously.
