Mechanical contraceptive methods

Mechanical contraception is the prevention of pregnancy through mechanical barriers. Methods for this are listed below. The condom is a contraceptive used by the man by slipping it over the erect limb.

It is considered to be the contraceptive of first choice, as it not only offers very good protection when used correctly, but also protects against sexually transmitted diseases. The diaphragm, also called vaginal pessary, consists of a spring ring covered with a silicone membrane. It is adjusted by the doctor so that it completely covers the cervix and can be inserted before sexual intercourse.

An additional gel is used to prevent the sperm from moving. The copper chain is attached to the upper part of the uterus and consists of a surgical thread to which copper elements are attached. As with the copper spiral, the copper ensures that the sperm are restricted in their mobility and cannot fertilise the female egg.

The method is considered very safe and can even be used as emergency contraception after sexual intercourse to stop fertilization of the egg. The copper spiral consists of a plastic anchor wrapped with copper wire. The coil is inserted by a gynaecologist and then checked by ultrasound.

These examinations should be performed at regular intervals. It is suspected that the copper changes the mucus of the female genital tract in such a way that the sperm are restricted in their mobility. With a Pearl Index of 0.9 – 3, it is a very safe contraceptive.

and What does the coil cost? The LEA contraceptivum is inserted into the vagina and can remain there for about 48 hours. An additional gel ensures further safety.

It is important that the LEA remains in the vagina for 8 hours after intercourse, even though the maximum wearing time has been exceeded. The safety is considered controversial due to the less than optimal study design.It can be placed over the cervix before intercourse and thus protects the sperm from entering the uterus. Before use, the size should be adjusted by a gynaecologist to ensure optimal protection. The safety varies greatly. In general, it can be said that the cervical cap works worse in women who have already given birth.
