12.10. Research, in particular biomedical research, has been instrumental in giving more and more people access to a greater range of safe and effective modern methods for regulation of fertility. However, not all persons can find a family-planning method that suits them and the range of choices available to men is more limited than that available to women, and the growing incidence of sexually transmitted diseases, including HIV/AIDS, demands substantially higher investments in new methods of prevention, diagnosis and treatment. In spite of greatly reduced funding for reproductive health research, prospects for developing and introducing new contraceptive and regulation of fertility methods and products have been promising. Improved collaboration and coordination of activities internationally will increase cost-effectiveness, but a significant increase in support from Governments and industry is needed to bring a number of potential new, safe and affordable methods to fruition, especially barrier methods. This research needs to be guided at all stages by gender perspectives, particularly women's, and the needs of users, and be carried out in strict conformity with internationally accepted legal, ethical, medical and scientific standards for biomedical research.
