Menstrual Blood Loss Measurement with Gynaeseal

Abstract

The diagnosis of menorrhagia is usually based on the subjective complaint of heavy menstrual bleeding, although up to 50% of women describing menorrhagia have measured menstrual loss within normal limits. Treatment is usually started without first establishing an objective diagnosis, because menstrual blood loss measurement is not widely available to clinicians. Current laboratory methods of measuring menstrual loss involve extraction of menses from sanitary wear. Many women find collection of sanitary wear unacceptable and laboratory staff find the menstrual extraction procedure unpleasant and time-consuming. We investigated the use of Gynaeseal, a vaginally placed latex menstrual seal, in women with normal menstrual loss (n = 10) and menorrhagia (n = 12) with regard to its suitability for the measurement of menstrual loss and efficacy as alternative sanitary protection. Twenty-one of the 22 women found the device easy to insert, but 16 found it messy to remove. All of the 6 couples having coitus found the device caused no discomfort. All women with menorrhagia and 4 of 12 women with normal menstrual losses were dissatisfied with the menstrual seal provided by gynaeseal. Gynaeseal does not contain menstrual blood efficiently in women with menorrhagia and is therefore unsuitable for the measurement of menstrual blood loss.
