Final answer:
True, latex condoms are not 100% effective in preventing pregnancy or STI transmission; proper use can reduce the risk but not completely eliminate it due to factors like potential breakage and incorrect usage.
Step-by-step explanation:
True, latex condoms are not 100% effective in eliminating the risk of pregnancy or transmission of STIs. Even with perfect use, condoms have a failure rate due to various factors such as breakage or incorrect usage. Proper use of condoms can significantly reduce the risk, but they are not foolproof.
For instance, pathogens may be present on areas of the body not covered by condoms, and there is a possibility of them breaking during intercourse. It's also critical to avoid using oil-based lubricants with latex condoms, as they can weaken the latex, increasing the risk of breakage. To enhance their effectiveness, condoms should be used in combination with spermicides, which can lower failure rates more than when either method is used separately.
