Do all types of condoms offer protection against the transmission of HIV?
No. Although there are a few differnt types of condoms, only latex condoms offer STD protection. Condoms made from animal membranes have pores in the condom- these allow HIV to pass through it. If you want to prevent pregnancy, it is also good to use a spermicide called nonoxynol-9. Nowadays, many condoms have nonoxynol-9 in them.
