Most of the scientific community and the public recognize the importance of steroidal contraception and the improvements which have been made in their formulation. There is evidence that reduced dosage has been associated with a reduction of side-effects, including those of a more serious nature. At the same time, the prohibitive cost of new drug development, in time, manpower and economic terms, makes it essential to extract the maximum value from those steroids currently in use. Thus the search continues to produce a formulation which maintains efficacy and cycle control and which provides the least disruption of normal metabolic processes.
