Steroidal contraception in the '80s. The role of current and new products

The future role of steroidal contraceptives in fertility management will be affected by rapid increases in population size in less-developed countries. Assuming that new serious risks with the use of steroidal contraception do not emerge and that radical, new technology does not replace this method, we can expect its continuing, important role in family planning programs. New compounds and delivery systems are now being studied. Within a few years a variety of long-acting and alternative delivery systems is likely to become available, including injectables and implants in biodegradable carriers and vaginal rings.
