ABSTRACT The hormone-producing mesenchymomas of the ovaries can be divided into androblastomas and gynaecoblastomas. The former are derived from »male« elements, and consist of Sertoli-cell tumours and Leydig-cell tumours. The latter arise from »female« elements and consist of granulosacell tumours and theca-cell tumours. Sertoli-cell tumours and granulosacell tumours produce oestrogens, while Leydig-cell tumours and theca-cell tumours produce oestrogens or androgens. Histologically, androblastomas and gynaecoblastomas are often difficult to distinguish. Since no »female« elements occur in a testicle, a granulosa-cell tumour in a testicle is improbable. Gynandroblastomas, therefore, can only be found in an ovary.

SUMMARY The metabolism of [4-14C]progesterone and [4-14C]androst-4-ene-3,17-dione (androstenedione) by a granulosa-theca cell tumour of the ovary, 310 g. in weight, removed from a 43-year-old post-menopausal woman has been studied in vitro. The experiments provided no evidence that the tumour could utilize progesterone as an oestrogen precursor. However, the tumour tissue converted androstenedione to oestrone and oestradiol-17β. The major metabolite of progesterone was 20α-hydroxypregn-4-en-3-one. These results are discussed in relation to current theories of the synthesis of steroids in the ovary.
