Condoms
Condoms are one of the most accessible and widely used mechanical contraceptives. They are thin, flexible sheaths typically made from latex, polyurethane, or natural materials like lambskin.
Used during sexual intercourse, condoms act as a barrier, preventing sperm from reaching the vagina and reducing the risk of sexually transmitted infections (STIs). Their effectiveness largely depends on correct and consistent use.
Condoms are convenient, easily available without a prescription, and offer a dual benefit of contraception and STI protection.
Diaphragms
A diaphragm is a shallow, dome-shaped cup made of silicone that a person inserts into the vagina before intercourse, covering the cervix.
It acts as a physical barrier, blocking sperm from entering the uterus. Used in conjunction with spermicide, which immobilizes sperm, diaphragms are reusable and offer a non-hormonal contraceptive option.
However, they require proper fitting, insertion technique, and consistent use to be effective. Diaphragms should be left in place for several hours after intercourse and must be checked periodically for proper positioning and any damage.
