This method is used for women
with blocked damaged or missing fallopian tubes, endometriosis, unexplained
infertility or whose partners have low sperm counts. The woman is
given daily hormone injections to stimulate egg production. Sonograms
and blood tests are used to monitor ovarian response. When the in
vitro team determines that the eggs are fully mature, an aspirating
needle is inserted into the ovary (under sedation or a local anesthetic),
and the eggs are removed. The eggs are then placed into a special
culture medium, a sperm specimen from the male is gently washed and
added, and the sperm-egg culture is then placed in an incubator. Three
to five days later, when normal fertilization and embryo growth have
been confirmed, embryos are transferred into the uterus with a thin
catheter. Embryo transfer is a painless procedure. |
