A diaphragm tampon applied to an ovulation method in a birth control system.
Gynaeseal is a re-usable diaphragm tampon made from latex which forms a unique cervico-vaginal seal and isolates menstrual loss. In a prospective study involving 80 women, Gynaeseal was offered in combination with the Billings Ovulation Method in an advised birth control system. This system included: use of the diaphragm tampon during the menstruation-fertile phase interphase; periodic abstinence during the overtly fertile phase of the cycle; and if extreme reliability was required, for a further 2 days after the Billings method 'rules' allow resumption of intercourse. The diaphragm tampon successfully complemented the Billings Ovulation Method with 44 women (60.4%) assessing the GOM System as being as good, or better than, currently available reversible methods. It functioned effectively as a tampon with 50% (31 women) stating that they used the product as a contraceptive. One woman claimed an unplanned pregnancy. No significant medical complications were recorded. The product has major advantages as a tampon: it is easily and accurately inserted because of the efficient applicator; it isolated menstrual loss within a collection chamber; it protects the cervix; and it facilitates sexual activity. Based on a minimum effective diameter (62mm), the diaphragm tampon does not interfere with the normal physiology of the vagina. There appeared to be no significant distortion of normal adult pelvic anatomy, and properly placed, no sensation of the diaphragm tampon's presence. Regarding insertion of the diaphragm tampon using the spiral-curved applicator: 31 women (42.5%) had little or no difficulty; 29 (39.7%) moderate difficulty; 13 (17.8%) experienced serious difficulty; and 7 (8.7%) were unable to use the product.
