An insulin nasal spray could help with polycystic ovary syndrome

Most women with polycystic ovary syndrome often struggle to maintain a steady weight. A nasal spray of insulin might help such women burn calories, according to preliminary research in sheep, which can show many of the same symptoms of PCOS. A trial in women with PCOS is now being planned.

Around 7 to 8 per cent of women have polycystic ovary syndrome, which affects the way ovaries work. Women with PCOS often have irregular periods and can find it difficult to get pregnant.
