Advances in Reproductive Science - Last Two Decades

February 21, 2012 | Comments: 0 | Views: 203

Reproductive science, like just about all fields of medicine and science, has taken tremendous leaps and bounds over the last two decades. Going back a bit further, the first successful 'test tube baby' was born in 1978-a feat for which physiologist Robert Edwards was awarded the Nobel Prize in Physiology or Medicine in 2010. Since then, the procedure and the field as a whole has gone through tremendous advancement to improve the procedure's success rates, develop new treatments, and make the procedure safer and more affordable for the average couple struggling with infertility.

Through the years various procedures have been developed to improve the process of selecting embryos for transfer to the uterus with the in vitro fertilization procedure. Preimplantation genetic diagnosis (PGD) is an example of one of these procedures. It is used to screen for certain genetic disorders or abnormalities that may affect the development of the fetus or the chances of a successful pregnancy. It has led to controversy within the scientific community as well as in society as a whole, as some see it as a way of altering the genetic composition of a society as a whole. Still, others see it for its potential in identifying potential genetic disorders.

Intracytoplasmic sperm injection (ICSI) is another procedure used as a sort of 'add-on' to in vitro fertilization, and is usually used in cases of severe male infertility. The procedure involves the injection of a sperm into an egg to form an embryo. It can be used to increase the chances of creating an embryo, but once the embryo is created the chances of success when ICSI is used with IVF are no greater than IVF alone. It began to be used as a treatment in the early and mid-nineties, and has helped many couples overcome severe male infertility problems to form embryos needed for IVF procedures.

Cryopreservation, or embryo freezing, is a process of freezing embryos for use in later cycles of IVF and other assisted reproductive technologies. Since the first baby was born from a frozen embryo in 1984, hundreds of thousands of babies have been born with the procedure. The increased prevalence of this service has helped to cut down on the cost of subsequent IVF cycles, as the process of retrieving eggs and sperms and creating the embryo is replaced with the use of the frozen embryos from previous sessions of the procedure.
