Infertility
Female infertility treatments
By Michael Russell
Once the probable causes of infertility have been identified,
treatments can begin. If irregular ovulation or lack of ovulation
is the problem, ovulation may be induced with medication. These
medications are the well-known fertility drugs. It is important
to remember that these fertility drugs are helpful only if the
infertility is caused by a problem with ovulation; they cannot
help at all if the infertility is caused by something else.
The most commonly used medication to induce ovulation is called
Clomid (clomiphene citrate). Through its effect on the hypothalamus,
clomiphene citrate stimulates a release of follicle stimulating
hormone (FSH) and luteinizing hormone (LH) from the pituitary.
FSH and LH are the hormones that act on the ovary to cause the
ripening and release of eggs. The medication is taken in the form
of a pill for five days during the month. Minor side effects include
hot flashes and lower abdominal discomfort. Clomiphene citrate
substantially increases the chances of having twins by stimulating
two eggs to ripen instead of one. It increases the chances of
having triplets and quadruplets only minimally.
In the cases where Clomid doesn't work, a second type of fertility
medication must be used. This medication is called Pergonal (or
human menopausal gonadotropin) and must be given by injection
every day until ovulation occurs. This treatment is both costly
and time-consuming and a woman must be closely watched for any
adverse side effects. By causing several eggs to ripen at one
time, the use of this medication can result in triplets or quadruplets.
Ultrasound monitoring and hormone testing have helped lower the
numbers of unwanted multiple births. Serious side effects of Pergonal
include large ovarian cysts and massive shifts in body fluids.
Problems with the fallopian tubes may be treated surgically.
The fallopian tubes may have been blocked as a result of a congenital
abnormality, scarring subsequent to a previous pelvic infection
or to endometriosis, or previous pelvic surgery. Sometimes the
fallopian tubes themselves are normal, but adhesions surrounding
them prevent the egg and sperm from meeting.
There is a reasonable chance that the surgical removal of the
adhesions will improve fertility. Unfortunately, when repairing
the fallopian tube requires major reconstructive surgery (tuboplasty),
the success rate is much lower. Even when it is possible to open
the fallopian tubes, tubal function does not always return to
normal and the infertility may persist. Frequently operating microscopes,
very fine instruments and lasers are used to improve the success
rate of tubal surgery.
An experimental procedure that may eliminate the need for surgery
in some cases of blocked fallopian tubes has been adapted from
a technique used to unclog coronary arteries. A catheter carrying
a small balloon is threaded through the uterus into the blocked
tube. When the balloon is inflated, the fallopian tube is stretched
and the obstructive tissue is washed out.
Other treatments are available for other specific causes of infertility.
For example, treatment of a genital infection may correct the
infertility, especially if the partner is treated simultaneously.
Sometimes problems with the cervical mucus may be treated by the
administration of low doses of estrogen.
