Answer 1

Answer:

A. GIFT and ZIFT

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.
