FAQ
Q: What is Infertility?
A: Infertility is a disease of the reproductive system that impairs
one of the body's most basic functions: the conception of children.
Conception is a complicated process that depends upon many factors:
on the production of healthy sperm by the man and healthy eggs by
the woman; unblocked fallopian tubes that allow the sperm to reach
the egg; the sperm's ability to fertilize the egg when they meet;
the ability of the fertilized egg (embryo) to become implanted in
the woman's uterus; and sufficient embryo quality. Finally, for the
pregnancy to continue to full term, the embryo must be healthy and
the woman's hormonal environment adequate for its development. When
just one of these factors is impaired, infertility can
result.
Q: What Causes Infertility?
A: No one can be blamed for infertility any more than anyone is to
blame for diabetes or leukemia. In rough terms, about one-third of
infertility cases can be attributed to male factors, and about
one-third to factors that affect women. For the remaining one-third
of infertile couples, infertility is caused by a combination of
problems in both partners or, in about 20 percent of cases, is
unexplained. The most common male infertility factors include
azoospermia (no sperm cells are produced) and oligospermia (few
sperm cells are produced). Sometimes, sperm cells are malformed or
they die before they can reach the egg. In rare cases, infertility
in men is caused by a genetic disease such as cystic fibrosis or a
chromosomal abnormality. The most common female infertility factor
is an ovulation disorder. Other causes of female infertility
include blocked fallopian tubes, which can occur when a woman has
had pelvic inflammatory disease or endometriosis (a sometimes
painful condition causing adhesions and cysts). Congenital
anomalies (birth defects) involving the structure of the uterus and
uterine fibroids are associated with repeated miscarriages.
Q: What is In Vitro
Fertilization?
A: In infertile couples where women have blocked or absent
fallopian tubes, or where men have low sperm counts, in vitro
fertilization (IVF) offers a chance at parenthood to couples who
until recently would have had no hope of having a "biologically
related" child. In IVF, eggs are surgically removed from the ovary
and mixed with sperm outside the body in a Petri dish ("in vitro"
is Latin for "in glass"). After about 40 hours, the eggs are
examined to see if they have become fertilized by the sperm and are
dividing into cells. These fertilized eggs (embryos) are then
placed in the women's uterus, thus bypassing the fallopian tubes.
IVF has received a great deal of media attention since it was first
introduced in 1978, but it actually accounts for less than five
percent of all infertility treatment in the United States.
Q: Is In Vitro Fertilization
Expensive?
A: The average cost of an IVF cycle in the United States is
$12,400. Like other extremely delicate medical procedures, IVF
involves highly trained professionals with sophisticated
laboratories and equipment, and the cycle may need to be repeated
to be successful. While IVF and other assisted reproductive
technologies are not inexpensive, they account for only three
hundredths of one percent (0.03%) of U.S. health care costs.
Q: Does In Vitro Fertilization
Work?
A: Yes. IVF was introduced in the United States in 1981. Since
1985, when we began counting, through the end of 2006, almost
500,000 babies have been born in the United States as a result of
reported Assisted Reproductive Technology procedures (IVF, GIFT,
ZIFT, and combination procedures). IVF currently accounts for more
than 99% of ART procedures with GIFT, ZIFT and combination
procedures making up the remainder. The average live delivery rate
for IVF in 2005 was 31.6 percent per retrieval--a little better
than the 20 per cent chance in any given month that a
reproductively healthy couple has of achieving a pregnancy and
carrying it to term. In 2002, approximately one in every hundred
babies born in the US was conceived using ART and that trend
continues today.
