In vitro fertilization 1986. New procedures and new questions

The number of infertile couples undergoing treatment by means of in vitro fertilization and embryo replacement is still increasing at a logarithmic rate from the first successful delivery in July 1978. At the present time, several hundred centers around the world are treating patients and had produced in excess of 2,200 live births by fall of 1985. Recent advances including better treatment regimens to increase the number of recoverable oocytes, refinements of laboratory procedures, less invasive oocyte recovery procedures, and the development of embryo freezing should lead to wider availability, lower cost, and most importantly, higher success rates of successful pregnancy establishment. Along with these advantages, the increased number of oocytes and embryo freezing have raised certain questions concerning the rights and obligations of doctors, parents, and even embryos.
