Diaphragm | Pearl Index

Diaphragm

The diaphragm is inserted into the vagina before sexual intercourse, so that it completely covers the cervix and prevents sperm from travelling. It is made of plastic, which must also be covered with a gel that also has an inhibiting effect on sperm.The diaphragm must be left in the vagina for up to 8 hours after intercourse. When used properly, it has a Pearl index of 1-8 with gel and up to 20 without gel. This means that out of every 100 women, 1-20 women become pregnant.

Hormone Spiral

The hormone coil is inserted into the uterus like the copper coil. It releases progestins in low doses. The motility of the sperm is reduced, as is the build-up of the lining of the uterus, so that implantation of the egg is not possible. In some cases, ovulation is completely suppressed by the hormonal influence. The hormone coil is a very safe contraceptive method with a Pearl index of 0.16.

NRP

NFP is an abbreviation for natural family planning, it is also called temperature method. During the menstrual cycle, the body temperature (basal body temperature) fluctuates by up to one degree. The temperature increase is most pronounced around ovulation.

For at least 3 days, the temperature must be at least 0.2 degrees higher than the previous 6 days. The day of ovulation can then be determined retroactively and the infertile days calculated. For this method, a woman must be intensively engaged with her body. When used carefully, the method has a Pearl Index of 0.8-3.

Gynefix

Gynefix is the trade name of the currently used copper chain (see section Copper Chain). The Pearl index is 0.1-0.5.

Contraception computer

The contraceptive computer is one of the natural methods of contraception. By analyzing body temperature (basal body temperature), hormone concentrations in morning urine and the consistency of the cervical mucus, the computer calculates the time of ovulation and the subsequent fertile days. There are different types of computers that record different hormones.

The Pearl Index depends strongly on the individual computers. The market for contraception computers is now large. However, many products have a very high index and should rather be used to determine the fertile days if you are planning to have children.
