In Vitro Fertilization (IVF)
IVF, or In-Vitro Fertilization, is a procedure offered to suitable candidates wherein mature eggs are collected from a woman's ovary after the ovaries have been artificially stimulated. The eggs are then placed with the sperm in the laboratory. Fertilization happens without further intervention. The embryos that develop after 2 to 5 days are collected and one or two are transferred to the woman's uterus. One or more embryos, after successful treatment, will then implant in the lining of the uterus and a fetus will develop from each embryo. The woman will then proceed with the pregnancy as though she had conceived through natural means.
