Other Treatment
Some couples have known
problems that are preventing the sperm and egg from travelling to the fallopian
tubes, fertilizing, and implanting in the uterus where they develop into a
fetus. Other couples have unexplained
infertility and want to increase their chances of
pregnancy. Insemination and assisted reproductive technology (ART) procedures
can improve their odds of pregnancy by introducing the sperm to the egg in the
woman's reproductive tract (insemination) or the laboratory (ART).
Insemination procedures flush the sperm through a
thin, flexible tube directly into a woman's
vagina,
cervix, uterus, or fallopian tube
. Insemination procedures put sperm
closer to the egg, to overcome fertility barriers such as low sperm count and
cervical mucus. They are also used with donor sperm and can be combined with
other fertility treatments, such as clomiphene or hormone shots.
Assisted reproductive technologies (ART) are
procedures to remove eggs from a woman's ovaries (or use donor eggs) and
fertilize them with sperm outside the body. One or more fertilized eggs are
then transferred to the woman's uterus or fallopian tubes. ART is used to treat
infertility caused by problems with fallopian tubes, ovulation, and sperm, as
well as endometriosis and unexplained infertility.8
These expensive and complex procedures are typically used only after more
conservative treatment methods have failed.
In order to closely
time and control the success of an ART procedure, doctors commonly control the
ovaries with hormone treatment. First, one kind of hormone is used to "shut
down" the
pituitary gland, which in turn stops the
ovaries from making eggs (menopausal
symptoms are common). This is called pituitary down-regulation with a GnRH
analogue. Then, ovulation-stimulating medicines are used to trigger ovulation
on a schedule. This process is also used before some insemination procedures.
For more information, see the Medications section of this topic.
Complementary and alternative treatments include the use of
acupuncture and dietary changes as well as relaxation techniques and mind-body
medicine. Early studies are promising about acupuncture, which may be effective
for improving sperm quality and enhancing IVF success rates. It is important to
talk with your doctor before you use any complementary or alternative
treatments.
Other Treatment Choices
Insemination procedures include
artificial insemination (AI) and intrauterine insemination
(IUI).
Assisted reproductive technologies include:
- In vitro fertilization (IVF), mixing
eggs with sperm outside the body; one or more fertilized eggs are then
transferred to the uterus using a thin flexible tube (catheter) inserted
through the cervix.
- Intracytoplasmic sperm injection
(ICSI), injecting a sperm into an egg and then using a catheter inserted
through the cervix to transfer the egg to the uterus.
Gamete or zygote intrafallopian transfer (GIFT or ZIFT) is
rarely used because success rates with IVF are as good or better.
For couples with sperm-related infertility, ICSI can be used to achieve
the fertilization stage of the in vitro fertilization process.
What To Think About
ART makes it possible to use
donor eggs or sperm when it isn't possible to obtain healthy eggs and sperm
from one or both partners. Insemination procedures make it possible to use
donor sperm.
Overall, IVF-related injections, monitoring, and egg
harvesting procedures are emotionally and physically demanding of the female
partner. Superovulation with hormones requires regular blood tests, daily
injections (some of which are quite painful), and frequent monitoring by your
doctor. Other complications, such as
ovarian hyperstimulation syndrome, can result
(although they are very rare) from hormone shots and assisted reproductive
technology such as IVF.
Before deciding on ART treatment, consider
the possible
emotional and social, financial, religious,
ethical and legal questions questions that may come up
for you and your partner.
Should I have infertility
treatment?
Should I have a tubal procedure or in vitro
fertilization for tubal infertility?
Should I consider adoption as
an alternative to infertility treatment?

egg collection procedures, see

If you have several
miscarriages or unsuccessful IVF attempts, talk to
your doctor about genetic testing.
