Having worked with diaphragms for over 15 years, I’ve noticed a small but consistent number of traditional diaphragms that have been flagged by users or their doctors due to mis-shaping.
The photo above is one of many that illustrate the situation. While the vagina is not a perfectly circular shape to precisely match the form of a new diaphragm, it still needs to form a reliable seal to be an effective contraceptive.
Protocol dictates that we escalate such issues to the manufacturer for their advice. The response we received was:
“…there would be no expected reduction from the pictures you sent – the diaphragm never worked by creating a “seal” per se – The diaphragm really works by keeping spermicide applied to the cervical os…”
Although there was an irreversible change in the diaphragm’s shape, to a certain extent, it wouldn’t affect the contraceptive efficiency of the device. However, such occurrences did impact the users’ confidence. Diaphragm users need to feel confident in using their device correctly while also feeling relaxed to enjoy intercourse. The thought of relying on a wonky-looking contraceptive device clearly affected users’ perception of its efficiency, even though there may have been no actual impact in reality.
So how does these deformities happen?
Milex diaphragms are silicone membranes stretched over a metal spring. There are two different types of metal spring used: Omniflex and Arcing. The primary difference lies in how these springs bend and flex during insertion.
While solid and reliable, Omniflex and Arcing springs are metallic and can deform under extreme stress, which may occur due to improper handling or robust use.
Singa and Caya diaphragms both utilize polymer compounds for their springs, whilst fully adhering to ISO 8009: 2016 standards for contraceptive diaphragms.
These modern springs are meticulously designed to offer exceptional mechanical strength, chemical resistance, and thermal stability. Unlike older metal springs, they resist deformation under stress, ensuring a more secure and reliable fit.
One notable advantage of polymer springs is their lighter weight compared to metal springs. Despite their lighter weight they still retain their strength when expanding into position for a better fit, which is a crucial attribute for a contraceptive diaphragm.
