The female condom and AIDS
19 октября 2000 года.
The female condom is a soft but strong sheath made of clear polyurethane plastic. The sheath has two plastic rings at either end. The one at the closed end is used to help with insertion and to keep the condom in place against the cervix. The ring at the open end is slightly larger and remains outside the vagina, covering both the woman's genitalia and the base of the man's penis.
