Who benefits from oestrogen rings?
At present the only oestrogen ring on the market is a topical one. This can remain in situ for up to three months and is particularly suitable for the elderly with persistent urinary problems and those with atrophic vaginitis. Other topical oestrogen preparations such as pessaries, creams and tablets are equally useful. 12. Should women using vaginal oestrogens who have not had a hysterectomy be prescribed a progestogen to protect the endometrium? Topical vaginal oestrogens are not absorbed systemically and confer no benefits except directly to the vagina. They do not cause endometrial proliferation so a progestogen is not needed. Although the manufacturers recommend a maximum of three months, there is no evidence that longer therapy causes untoward effects. Personal experience of long-term therapy backed up with annual ultrasound scanning of the endometrium confirms this. Mr Peter Bowen-Simpkins is consultant gynaecologist and Medical Director of the London Women’s Clinic.
