Diaphragms are great natural, green, non-hormonal contraceptive option. A diaphragm is a latex or silicone cup with a firm flexible rim and shallow dome used for contraception. Spermicide is applied to the outer surface of the diaphragm to stop sperm from creeping in through the sides, and must be used with diaphragms in order to prevent pregnancy successfully.
Ortho-McNeil-Janssen Pharmaceuticals, Inc, produce the Ortho Coil Spring Diaphragm (discontinued 2008) and the Ortho All-Flex Arcing Spring Diaphragm, which is available in 4 sizes (65, 70, 75 and 80mm) .
Semina Industries produce the Semina Diaphragm in Brazil. It is a clear silicon diaphragm available in six diameter sizes, from 60 to 85mm, in 5mm increments.
Lastly, there is the Milex Wide Seal Diaphragm, a silicone diaphragm with a shallow dome and a wide rim with an arcing or omniflex spring. It has a small skirt around the rim intended to hold gel in place and improve the seal. It is available in eight diameter sizes, from 60 to 90mm, in 5mm increments.
The Milex Wide Seal Diaphragm with both arcing and Omniflex Springs are now both in stock.
The sizing of a diaphragm depends upon the size of the vaginal cavity of the user. A Doctor or Gynaecologist is needed to ascertain the correct size. Every 6-12 months the user should check to see if that size is still correct and in addition if there has been any weight loss or gain of more than a few kilos or a pregnancy, abortion or miscarriage, then the sizing should be checked again.
You should NEVER guess your correct size and you should NEVER assume it will stay the same. An incorrectly sized diaphragm WILL increase the risk of pregnancy.
During the check up to ensure that a diaphragm is the best barrier contraceptive choice for you and to measure the correct size, the Doctor or Gynaecologist will also be able to show you how to correctly insert and remove the diaphragm. Not inserting it or removing it correctly will increase the risk of pregnancy.
It is crucial that a Doctor or Gynaecologist is consulted to confirm a diaphragm is a suitable contraceptive method for you, to correctly measure you for your diaphragm and to instruct you in its correct use. DO NOT attempt to purchase or use a diaphragm until after such a consultation.

Diaphragms can not be used during menstruation because it would interfere with the natural flow of menstrual fluid. Furthermore, because you are not fertile during menstruation, contraception would not be needed to prevent pregnancy. Intercourse only has the risk of pregnancy for approximately 6 days per cycle during your Fertility Window. A healthy egg is only fertilisable for 18-24 hours and sperm cannot survive for more than 5 days inside a woman, so that span of 6 days (5 days before ovulation and the day of ovulation) is really the only time when barrier contraception needs to be used for pregnancy protection.
Contraceptive Technology reports that the method failure rate of the diaphragm with spermicide is 6% per year. The actual pregnancy rates amongst diaphragm users vary depending on the population being studied, with yearly rates of 10% to 39% being reported. Unlike some other cervical barriers, the effectiveness of the diaphragm is the same for women who have given birth as for those who have not.
The low effectiveness can be traced to incorrect usage, therefore it is imperative to check with your doctor or sexual health care consultant in order to become a successful diaphragm user.
If you or your partner has a latex allergy, do not use a latex diaphragm.
Diaphragms are associated with an increased risk of urinary tract infections (UTIs). Urinating before inserting the diaphragm and also after intercourse may reduce this risk. The increased risk of UTIs may be due to the diaphragm applying pressure to the urethra, which is common if the diaphragm is too large, and causing irritation by preventing the bladder from emptying completely. However, the spermicide Nonoxynol-9 (N-9) is itself associated with increased risk of a UTI, yeast infection, and bacterial vaginosis.
For this reason, some experts advocate the use of lactic acid based spermicides or contraceptive gel such as ContraGel which might have fewer side effects. It has also been suggested that, for women who experience side effects from Nonoxynol-9, it may be acceptable to use the diaphragm without any spermicide. One study found an actual pregnancy rate of 24% per year in women using the diaphragm without spermicide; however, all women in this study were given a 60mm diaphragm rather than one being fitted individually by a clinician. Other studies have been small and have given conflicting results. The current recommendation is still for all diaphragm users to use spermicide or contraceptive gel with the device.
Toxic shock syndrome (TSS) occurs at a rate of 2.4 cases per 100,000 women using diaphragms, almost exclusively when the device is left in place longer than 24 hours.
