Answer:
A. GIFT and ZIFT
Read Explanation:
Assisted Reproductive Technologies (ART)
Assisted Reproductive Technologies (ART) are medical procedures used to treat infertility and help individuals and couples achieve pregnancy.
These techniques involve the manipulation of eggs, sperm, and/or embryos.
Gamete Intra-Fallopian Transfer (GIFT)
GIFT is a procedure where mature eggs are surgically removed from a woman's ovaries and mixed with sperm in a laboratory.
The mixture of eggs and sperm (gametes) is then immediately transferred into the woman's fallopian tubes.
Fertilization occurs naturally within the fallopian tube, similar to natural conception.
Key Feature: Fertilization happens inside the body (in vivo).
Often considered a more 'natural' form of IVF as fertilization takes place within the fallopian tube.
Zygote Intra-Fallopian Transfer (ZIFT)
ZIFT is another ART procedure that involves fertilizing eggs with sperm in a laboratory, creating a zygote (fertilized egg).
The resulting zygotes are then transferred into the woman's fallopian tubes.
Key Feature: Fertilization happens outside the body (in vitro), and the resulting zygote is transferred into the fallopian tube.
This technique combines aspects of IVF and GIFT.
In Vitro Fertilization (IVF)
While not the direct answer, IVF is a foundational ART technique.
In IVF, eggs are retrieved from the ovaries and fertilized by sperm in a laboratory dish.
The resulting embryo(s) are then transferred into the uterus.
Key Feature: Fertilization happens outside the body (in vitro), and the embryo is transferred into the uterus.
