Contraceptive Diaphragm

Contraceptive Diaphragm

The contraceptive diaphragm is a latex or silicone cup placed on the cervix to prevent sperms from entering the uterus. Once the device is coated with a water-based gel from the inside, it will be at its most effective state, blocking and killing sperms.

How does it work?

  • The diaphragm acts as a physical barrier between the sperm and the cervix.
  • It should always be used with a gel that blocks and kills sperms. The water-based gel will form a physical barrier of cellulose in front of the cervix and decreases the PH of the vaginal liquid, reducing half of the ejaculated sperm cell.
  • The contraceptive diaphragm have to be placed in front of the cervix at least 2h before any sexual intercourses.
  • The cervical cap have to stay in the vagina at least 6h after your last intercourse but should not remain in the vagina for more than 24h altogether.
  • If a new sexual intercourse takes place within 6h, gel should be applied again with an applicator. The contraceptive diaphragm should not be withdrawn.
