Why ART procedure sometimes involves the use of donor eggs or donor sperms?
The correct option is D Both (A) and (B)
Common methods of ART
include:
1. In
vitro fertilization (IVF) - Fertilization
outside of the body. IVF is the most effective ART. It is often used when a woman’s
fallopian tubes are blocked or when a man produces too few sperm. Doctors treat
the woman with a drug that causes the ovaries to produce multiple eggs. Once
mature, the eggs are removed from the woman. They are put in a dish in the lab
along with the man’s sperm for fertilization. After 3 to 5 days, healthy
embryos are implanted in the woman’s uterus.
2. Zygote
intrafallopian transfer (ZIFT) or Tubal Embryo Transfer is similar
to IVF- Fertilization occurs in the laboratory. Then the very young embryo is
transferred to the fallopian tube instead of the uterus.
3. Gamete
intrafallopian transfer (GIFT) involves
transferring eggs and sperm into the woman’s fallopian tube. So fertilization
occurs in the woman’s body. Few practices offer GIFT as an option.
4. Intracytoplasmic
sperm injection (ICSI) is often used for
couples in which there are serious problems with the sperm. Sometimes it is
also used for older couples or for those with failed IVF attempts. In ICSI, a
single sperm is injected into a mature egg. Then the embryo is transferred to
the uterus or fallopian tube.
ART
procedures sometimes involve the use of donor eggs (eggs from another woman),
donor sperm, or previously frozen embryos. Donor eggs are sometimes used for
women who can not produce eggs. Also, donor eggs or donor sperm is sometimes
used when the woman or man has a genetic disease that can be passed on to the
baby.
So, the
correct answer is “Both A and B”.
