Non-latex versus latex male condoms for contraception.

The male condom, which consists of a thin sheath placed over the glans and shaft of the penis, is designed to prevent pregnancy by providing a physical barrier against the deposition of semen into the vagina during intercourse. Beginning in the 1990s, nonlatex male condoms made of polyurethane film or synthetic elastomers were developed as alternative male barrier methods for individuals with allergies, sensitivities or preferences that prevented the consistent use of condoms made of latex.
