In vitro fertilization (IVF) is an example of assisted reproductive technology (ART) that has become more common in recent decades. However, IVF is not without controversy. Which of the following aspects of IVF is most often contentious?
A) The number of fertilized ova normally exceeds the number of children that a woman
desires.
B) The success or failure of IVF rests on the genetic characteristics of sperm that comes from
a man unknown to the woman undergoing the procedure.
C) IVF is most common among women who have a history of elective abortion.
D) IVF is often undertaken without the consent of a woman's partner.
Ans: A
: In IVF, several fertilized ova are usually returned to the uterus to ensure that at least
one will survive. If more than one implants successfully, it is possible for the mother to have
multiple births. The alternative to this potential is the abortion of one of more of the implanted
ova, a practice that is controversial. IVF may or may not use sperm from an anonymous donor
and is not normally performed without the awareness or consent of the woman's partner. IVF
is not normally necessitated by prior elective abortions.
