In vitro fertilization and human embryo transfer

The techniques used in In Virtro Fertilization (IVF) have expanded significantly since the birth in 1978 of the first so-called "test-tube" baby. Technical advances, such as the use of a freezing technique known as cryopreservation and the application of drugs to stimulate the maturation of multiple ova during a woman's menstrual cycle, have contributed to improved successful pregnancy rates and also to wider uses of IVF as a means of treating infertility. This paper describes the techniques currently being used in this area of reproduction and also presents some of the problems associated with the uses of these techniques.,Abstract -- Background -- Human Reproduction -- Infertility -- The IVF Procedure -- How Successful is IVF? -- The Use of Super-Ovulatory Drugs -- Cryopreservation -- Research on Embryos -- Ethical, Social, and Legal Implications of IVF.,Irene Stith-Coleman, Analyst in Life Sciences, Science Policy Research Division,CRS 85-703 SPR,"April 12, 1985.",SuDoc# 14. 18/3
