What kind of condom is good for long-term contraception?

Patient's question:

No

Doctor's answer:

Okay, condoms are safe now, and their chance of blocking viruses is quite high. If they were harmful, they would have been taken off the market long ago, or there would be warnings! But the price of condoms should definitely not be too low; it's fine if they're average, and you must always check the production date.
