PIP: Despite the existence of many forms of contraceptive methods and agents, ample opportunity exists for new products. For example, there has been a large reduction in estrogen and progestogen content, and the development and introduction of a new class of progestogens over the past 30 years. Injectables, implants, prostaglandins, and antiprogestogens have also been developed. The authors, of Holland's Organon International, stress that the role of industry in contraceptive research and development is essential and should not be underestimated. Organon is presently working upon several projects involving many different approaches to contraception which will hopefully guarantee its continued role in the future as one of the major suppliers of innovative contraceptive methods. Sections consider why new contraceptives are necessary, expected advantages, major obstacles, cost structure of the pharmaceutical industry, and how industry selects research and development topics.^ieng
