Patient's question:

Married women who do not want to have more children
During sexual intercourse, is it healthier for women to use a diaphragm or not use a diaphragm and for men to wear a condom?

Doctor's answer:

Of course, it's better for men to wear condoms @ However, men often wear them reluctantly or avoid them due to inconvenience or discomfort during sex @ This can lead to unintended pregnancies for women @ Alternatively, sometimes condoms fall off inside the vagina, which can also result in pregnancy for women @
