Barriereverhütungsmitteln

Barriereverhütungsmitteln, also known as barrier methods of contraception, are devices or substances that prevent pregnancy by physically blocking sperm from reaching an egg or by creating a chemical barrier. These methods are used internally or externally by individuals or couples to control fertility.

Common types of barrier methods include condoms, diaphragms, cervical caps, and contraceptive sponges. Condoms, available for both penises and vaginas, are thin sheaths that collect semen. Diaphragms and cervical caps are dome-shaped devices inserted into the vagina to cover the cervix, often used with spermicide. Contraceptive sponges are also inserted vaginally to cover the cervix and contain spermicide. Spermicides themselves, available as creams, foams, gels, or suppositories, can also be used alone, though they are generally less effective when not combined with a physical barrier.

The effectiveness of barrier methods can vary depending on the specific type, correct usage, and individual factors. When used consistently and correctly, they offer a reliable form of contraception. Beyond pregnancy prevention, some barrier methods, particularly condoms, also provide protection against sexually transmitted infections (STIs). These methods are generally reversible and do not require medical procedures for insertion or removal, making them a flexible choice for many individuals. They can be used on demand, offering a spontaneous approach to contraception.
