Abstract: Non-hormonal contraception compositions and methods for contraception are provided. One embodiment provides an antibody or an antigen binding fragment thereof that specifically binds to one or more sperm antigens and inhibits the ability of anti-body-bound sperm to fertilize an egg. Typically, the antibody is a monoclonal antibody, for example a human or humanized monoclonal antibody. In one embodiment, the antibody or antigen binding fragment thereof specifically binds to CD52g expressed on vertebrate, for example human, sperm cells and inhibits, blocks, or reduces the ability of the antibody-bound sperm to fertilize an egg. In one embodiment the antibody contains a membrane anchor. The membrane anchor can contain transmembrane domains, glycosylphosphatidylinositol anchors, or myristoylation motifs.

Abstract: The present invention reveals a device, a kit and a method for simultaneously delivering and distributing at least one beneficial agent to both the cervical and vaginal lumen sides of a vagina. The device is made of a flexible circular rim and a flexible dome. The device can exist in either a relaxed state or in a compressed state. In the compressed state, pouches are formed for carrying and delivering the beneficial agent to both the cervical and vaginal lumen sides of the vagina.

Abstract: Certain antibody molecules are so stable and so potent at immobilizing sperm as well as the pathogens for sexually transmitted diseases (STDs) that they make possible new prophylactic contraceptive methods: (a) for men, a skin lotion containing antibodies against sperm and against STD pathogens to be applied to the penis and external genitals during sexual activity, thereby delivering prophylactically effective doses of antibodies to virtually all areas of skin and epithelia across which most STDs, including AIDS, are usually transmitted, and, during vaginal intercourse, the penis will deliver a contraceptively reliable dose of the antibodies to the cervical region of the vagina; and (b) for women, intrauterine devices (IUDs) and intravaginal devices (IVDS) that release antibodies into the uterus or into the vagina to provide continuous protection against pregnancy and STDs for periods of months to years.
