    A 23 year old woman was referred to the infertility clinic for subfertility and an ovarian tumour. She had been married for two years and reported having irregular periods every two or three months. She also had a history of mild dysmenorrhoea. She reported having gained 16 kg after marriage and developing excess growth of fine hair all over her body and face. She did not have galactorrhoea, acne, altered appetite, or thyroid symptoms. Apart from treatment for infertility (ovulation induction with clomifene citrate) her medical history was unremarkable. There was no family history of diabetes or hypertension.

    On examination she was moderately built with a body mass of index of 26 and normal secondary sexual characters. She had a slight excess of fine hair on her face and abdomen. Examination of the breasts and thyroid was normal. No masses were found on examination of the abdomen, and on bimanual examination the uterus was normal with no adnexal masses.

    A routine transvaginal scan in the outpatient clinic showed bilateral polycystic ovaries with a 4 cm complex cystic lesion in the left ovary (possibly a dermoid cyst) and minimal free fluid in the pouch of Douglas.
