Funding for reproductive research: the status and the needs.

Just to maintain the admittedly inadequate level of research in reproduction and contraceptive development attained in 1974 would require an investment of $143 million this year--a level that has not been reached. To take advantage of existing knowledge, at least $361 million would be required--increasing to $498 million by 1980. To achieve a high-priority research program--10 percent of health expenditures--would require $500 million this year--rising to $766 million by 1980.
