How
do injectable fertility agents work?
During a natural menstrual cycle, hormones from the
pituitary gland (LH & FSH) cause the growth of a
fluid-filled cavity, or follicle, within the ovary.
Although several follicles start to grow each month,
in a natural cycle only one will become mature enough
to ovulate its egg.
Pergonal, Puregon, and Gonal-F are
commercially available, natural forms of LH and/or FSH.
Together, they are known as gonadotropins. Gonadotropins
have been used for approximately 35 years to induce
or augment ovulation when all other simpler forms of
treatment have been unsuccessful.
Gonadotropins are not absorbed by
mouth, so they must be given by injection. However,
when injected (rather than secreted naturally from the
pituitary gland), gonadotropins tend to stimulate the
growth of more than one follicle. Close monitoring (by
blood tests and ultrasounds) is therefore necessary
to minimize complications such as ovarian overstimulation
and multiple pregnancies.
A second medication (hCG) is given
to trigger ovulation when blood tests and ultrasounds
indicate one to four mature follicles. Ovulation usually
occurs 36-48 hours after this final injection.

What
should I expect during treatment?
The treatment usually starts on day 3 or 4 of a menstrual
cycle and lasts approximately 8-12 days. We will teach
you or your partner to give your daily injections at
home.
  
You will have clinic appointments
every one to four days for blood tests and/or vaginal
ultrasound scans in order to monitor your response and
possibly adjust your dose. These visits will occur between
8:00 and 9:00 a.m. and will become more frequent toward
the time of ovulation. Although each woman and each
cycle is different this is an example of a treatment
cycle schedule:

What
is an IUI?
Sometimes, we offer an intrauterine insemination (IUI)
with your partner's sperm instead of, or in addition
to intercourse. This usually occurs approximately 36
hours after the hCG injection. A speculum is placed
in your vagina and a small tubing (catheter) is passed
through your cervix into your uterus. The sperm is slowly
injected directly into the uterine cavity and the catheter
withdrawn. The procedure takes only a few minutes and
should be relatively painless.

What
is "washed" sperm?
In nature, sperm are deposited in the vagina and then
they have to swim through the cervical mucus (which
traps lots of sperm). By doing an IUI, there may be
more sperm available at the site of fertilization, since
the cervix is bypassed. Because the sperm are placed
directly into the uterus in an IUI, they have to be
washed first, to get rid of any dead cells, bacteria,
and the seminal fluid. The sperm wash procedure takes
about 1 hour, so the IUI procedure is scheduled 1 ½
hours after the sperm collection procedure to allow
the laboratory staff enough time to prepare the sperm
for insemination.

How
successful is this therapy?
In the general population, about 20 to 25% of healthy
fertile couples become pregnant each month they try.
In contrast, the pregnancy rate among couples with infertility
is usually about 2 to 5% per month. Gonadotropins usually
produce pregnancy rates of about 10 to 15% per cycle,
depending on the woman’s age, diagnosis and duration
of infertility. Among women with certain ovulatory disorders,
gonadotropins may even restore normal fertility rates
of 20 to 25% per month. If you do not become pregnant
within the first three treatment cycles, we will discuss
other options with you.
Approximately 10-20% of pregnancies
will miscarry, which is not substantially different
than the general population. There is no increase in
the risk of congenital abnormalities, ectopic pregnancies
or birth defects as compared to other women your age.

Are
there side effects from gonadotropin therapy?
Because your ovaries will be stimulated to produce more
than one follicle at a time, you may find that your
usual menstrual cycle symptoms are exaggerated. You
may experience bloating, breast tenderness, cramping,
pelvic "twinges", fatigue or headaches.

Are
there risks from this therapy?
Most women will produce 1-4 mature follicles during
treatment. Although not every follicle contains an egg,
the ovaries may occasionally overstimulate and produce
too many mature follicles. We try to minimize this by
frequent monitoring and dose adjustments.
Although ovulating more than one egg
may increase your chances of conceiving, it will also
increase your chance of having a multiple pregnancy.
Between 15-25% of all gonadotropin pregnancies are twins
(depending on the woman's age and the cause of her infertility)
while 1-3% of pregnancies result in triplets or more.
In such cases, a reduction procedure could be considered
to reduce a higher multiple pregnancy down to twins
if this is considered desirable by the patient or couple.
In about 1% of cases, ovarian hyperstimulation
syndrome (OHSS) may develop. In such cases the ovaries
become extremely enlarged and extra fluid accumulates
in the abdomen. This is a serious complication, which
requires bed-rest, intravenous fluids or even drainage
of the abdominal fluid. Rarely hospitalization may become
necessary.
If we think you are at high risk for
a multiple pregnancy or OHSS, we may withhold the ovulating
injection of hCG and "cancel" the cycle. Alternately,
we may suggest converting the cycle to an IVF cycle
as a safety measure. By retrieving the eggs from the
ovaries and transferring a limited number of embryos
back to the uterus, we can decompress the ovaries and
potentially lower the risk of multiple pregnancy and
OHSS. There is an additional fee
for an IVF conversion.
Fertility
drugs have not been proven to increase the risk
of breast, ovarian or uterine cancer. Women who have
never been pregnant have a higher risk of breast or
ovarian cancer. Several large follow up studies provide
reassurance that this risk is not increased following
the use of fertility drugs. Past or future use of the
birth control pill can lower your risk of ovarian cancer.
A yearly physical exam is important for the prevention
and early detection of all diseases.

What
is the cost of ovulation induction?
Please refer to our fee
guide for specific costs.
Although no two cycles are the same,
medication costs usually range between $700 and $1500
for each cycle. There is an additional cost for injection
supplies. You should check with your extended benefits
carrier to see if any of the drugs are covered, to what
extent, and for how many treatment cycles.
