IVF-in vitro fertilization
IVF, in vitro fertilization, is a procedure often used when a man has
low sperm counts or a woman's fallopian tubes are blocked. It enables
couples who until recently would have had no hope of producing a "biologically
related" child. A drug is administered to the woman which stimulates
her ovaries to produce multiple eggs. Once these are mature, the eggs
are removed and placed in a culture dish with the man's sperm for fertilization.
After about 40 hours, the eggs are examined to see if they have become
fertilized by the sperm and are dividing into cells. These fertilized
eggs, called embryos, are then placed into the uterus of the woman, thus
bypassing the fallopian tubes.
One downside to IVF is that it is quite expensive. This is due to the
delecate medical procedures involving many highly trained professionals
with sophisticated equipment. In the United States one cycle of IVF costs
approximately $12,400 and the cycle may need to be repeated if proved
to be unsuccessful.
The good news is that IVF really works and hundreds of thousands of babies
have been born this way. Nowadays almost one in every hundred babies born
in the united States was conceived using IVF together with GIFT and ZIFT.
IVF accounts for about 99% of all assisted reproductive techniques.
Two processes which are similar to IVF are GIFT and ZIFT.
