Summary
Brief summary
This study is designed to evaluate the efficacy and safety of oral Dehydroepiandrosterone (DHEA) 50mg daily, for 12 months in naturally menopausal women with low libido who are not receiving systemic oestrogen or oestrogen- progestin therapy.

Efficacy measures for the present study are effects on sexual function, wellbeing and menopausal symptoms. Safety measures will include endometrial assessment by transvaginal ultrasound (TVU), vital signs, lipid profiles, general electrolytes, effects on glucose metabolism and reports of adverse events.
