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.
月经过多的诊断通常基于月经过多的主观主诉，尽管描述月经过多的女性中有高达50%的人测量的月经失血量在正常范围内。通常在未首先确立客观诊断的情况下就开始治疗，因为临床医生无法广泛获得月经失血量的测量方法。目前测量月经失血量的实验室方法包括从卫生用品中提取经血。许多女性认为收集卫生用品不可接受，而实验室工作人员则认为经血提取过程不愉快且耗时。我们研究了一种阴道放置的乳胶月经密封装置Gynaeseal在月经失血量正常的女性（n = 10）和月经过多的女性（n = 12）中的使用情况，评估其对测量月经失血量的适用性以及作为替代卫生防护用品的有效性。22名女性中有21名发现该装置易于插入，但16名发现取出时很麻烦。6对有性行为的夫妇中，所有人都发现该装置不会引起不适。所有月经过多的女性和12名月经失血量正常的女性中的4名对Gynaeseal提供的月经密封装置不满意。Gynaeseal不能有效地容纳月经过多女性的经血，因此不适合用于测量月经失血量。
