Infertility - Assisted reproduction

1. The success rate has been increasing, and may
reach 25%. Actually, the success rate of in vitro
fertilization (IVF) exceeds that of normal
conception in a fertile couple in one cycle.
2. In vitro fertilization (IVF) consists of the egg
and sperm united in a test tube, and then the
pre-embryo is transferred to the uterus.
3. GIFT (gamete intrafallopian transfer) consists of
placement of egg and sperm in the fallopian tube.
4. ZIFT is zygote intrafallopian transfer where the
fertilized eggs are placed in the uterus or tubes.
5. Ovum conations combined with the man’s sperm
and IVF or GIFT can be used for women with
premature ovarian failure, ovarian dysfunction
caused by cancer, chemotherapy, radiation,
maternal chromosomal or genetic abnormalities,
or in women who have responded poorly to
ovulation inducers. Older women’s eggs are more
likely to have genetic abnormality and aneuploidy.
6. Sperm donation can come from the male
partner or donor. The sperm is then placed in
the uterus or used in IVF or GIFT. This may be
used for male infertility, male ejaculatory
dysfunction, post-radiation, chemotherapy or
surgery for cancer, chromosomal abnormalities,
or for women without a male donor.
