Double protection works by using two different methods of contraception simultaneously to increase the overall effectiveness in preventing pregnancy and sexually transmitted infections. For example, using a condom along with a hormonal contraceptive like the pill or an IUD provides a barrier method and a hormonal method of protection. This combination reduces the risk of both pregnancy and STIs, as condoms provide a physical barrier to prevent sperm from reaching the egg, while hormonal contraceptives prevent ovulation and thickening of cervical mucus to further prevent pregnancy. **

This default action could be opening a file with its associated application, launching a program, or opening a folder. The double-click speed can usually be adjusted in the system settings to accommodate different user preferences. **
