What is the mode of contraception involving barriers such as condoms or diaphragms called?

The mode of contraception that utilizes devices or materials to create a physical barrier preventing sperm from reaching the egg is known as barrier methods. These methods include, among others, condoms and diaphragms, which physically block sperm and can also provide some protection against sexually transmitted infections.

Barrier methods are unique in that they do not involve hormonal intervention or permanent solutions for contraception. Unlike hormonal contraception, which works by altering the body's hormonal balance to prevent ovulation, barrier methods rely on physical obstruction. These methods can be easily used on an as-needed basis, promoting advantages such as the ability to prevent pregnancy without long-term effects on the body. Furthermore, these methods do not lead to permanent sterility, as some permanent methods, like sterilization, do.

Overall, the effectiveness and safety of barrier methods make them a popular choice for individuals seeking to control their reproductive health while minimizing the risk of unintended pregnancies and sexually transmitted infections.
