It is a...: ... A specially designed contraceptive as vaginal contraceptive film, VCF, in which the spermicide, nonoxynol-9, is formulated in a film form so to insert into vagina easily about 30 minutes before intercourse. Inside the vagina, it melt with vaginal secretion and ready to immobilize sperms in contact. It is easy to use, no mess, but come with a low success of some 75% in a one-year use.
