Urgent Second Opinion Requested!?

I'm currently researching the effectiveness of condoms as barrier contraceptives, and also the preventative role they play in HIV transmission. I received an answer from an OBGYN that I found to be quite alarming. He told me that 1 in 6 women become pregnant from using condoms as their sole contraceptive (thus blowing the purported 2% failure rate out of the water), claimed that condom failure is "extremely common", and then stated that microscopic pores are existent within condoms, and that he had just stretched a latex condom over a light microscope under 200x magnification and witnessed "latex imperfections" everywhere. Now I find his information to be quite worrysome, statistically improbable, and misleading. Taking his information into account, it would appear that condoms are as good as useless in terms as serving as a prophylactic for both pregnancy and STD's. Opinions?
