The process of creating test-tube
babies is more commonly known as in vitro fertilization, IVF. Which of these statements is not
correct about IVF? (A) In IVF, the egg and the sperm
meet in a petri dish in a laboratory environment to produce embryos. (B) IVF produces embryos that can
be implanted immediately or cryopreserved for later pregnancies. (C) In IVF, the semen is
artificially placed in the uterus of the female for egg fertilization. (D) IVF allows many infertile
couples in the world to have babies.
IVF is a technique used in
artificial, or assisted, reproduction that helps many infertile couples have
children. During IVF, the sperm and eggs are
collected and combined outside the body in a petri dish for fertilization. This creates embryos that can be
transferred to the uterus immediately, or they can be frozen at very low
temperatures in a process called cryopreservation for future use.
Other methods of assisted
reproduction include artificial insemination where semen is transferred to the
uterus. And when the female ovulates, an
egg can then be fertilized. But this process is not IVF because
the sperm and eggs aren’t combined outside the body.
Therefore, answer choice (C) is
correct because it describes a technique that is not correct about IVF. In IVF, the semen is artificially
placed in the uterus of the female for egg fertilization.
