In
vitro fertilization(AE) or fertilisation(BE)
(IVF) is a technique in which egg cells are fertilized
outside the woman's body. It is a major treatment in infertility.
In brief, the process involves controlling the ovulatory process,
removing ova (eggs) from the woman's body and letting sperm fertilize
them in a fluid medium. The fertilized egg or embryo is then transferred
to the patient's uterus with the intent to establish a successful
pregnancy. "In vitro" is Latin for "in glass",
referring to the test tubes, however neither glass nor test tubes
are being used.
Initially the IVF was developed to overcome
infertility due to problems of the fallopian tubes, but it turned
out that it was successful in most infertility situations. The introduction
of ICSI addresses the problem of male infertility to a large
extent. Thus for IVF to be successful it may be easier to say that
it requires healthy ova, sperm that can fertilize, and a uterus
that can maintain a pregnancy. |
