Clomiphene
Citrate, or "Clomid"
is often referred to
as the "fertility
pill". It is used
to treat infertile women
who have an ovulation
problem. It works by
helping the pituitary
gland (located at the
base of the brain) improve
the stimulation of developing
follicles (eggs) in
the ovaries. Clomiphene
is most often prescribed
to those patients who
have been found to have
an abnormality with
their cycle, though
combined with intrauterine
insemination, it may
be useful in the treatment
of unexplained infertility.
Clomiphene is usually
prescribed for five
days each cycle, usually
beginning on day three
or five. Of all women
treated with clomiphene
60% to 80% will ovulate
normally. Nearly 10%
of women treated with
Clomiphene may experience
side mild side effects,
including hot flashes,
blurred vision, nausea,
bloating sensation,
and headaches. Serious
side effects are rarely
seen with clomiphene
therapy. The frequency
of twins occurring in
women who conceive while
taking clomiphene has
been reported to be
as high as 10%. In addition,
new studies suggest
that long-term use of
clomiphene for more
than 12 cycles may place
patients at an increased
risk of developing ovarian
cancer.
A number of studies
have confirmed a significantly
improved pregnancy rate
with injectable medications
that stimulate "superovulation".
This improvement in
pregnancy rate is due
primarily to the increased
number of eggs produced.
"Fertility drugs,"
including Pergonal,
Humegon, Metrodin, Gonal-F,
and Follistim are administered
beginning on the second
or third cycle day and
given for six to nine
consecutive days. Response
to these drugs is monitored
by frequent vaginal
ultrasounds and blood
estrogen determinations.
At a time in the cycle
when the ovarian follicles
reach a designated size,
and estrogen levels
are appropriate, an
injection of the hormone
HCG is given to trigger
ovulation. Ovulation
usually occurs 36-48
hours after the HCG
injection. Thus, intercourse
or insemination should
be timed accordingly.
Performing intrauterine
insemination may result
in an increase in the
number of sperm at the
site of fertilization
in the fallopian tube.
Generally only 1 of
2000 sperm ejaculated
into the vagina make
can later be found in
the fallopian tube.
Therefore, adding insemination
to stimulated cycles
may further improve
the pregnancy rate.
A possible side effect
of the injectable fertility
drugs is ovarian hyperstimulation,
a condition in which
the ovaries are tender
and enlarged. In severe
cases, a woman may have
swelling from retaining
excessive amounts of
body fluid in the tissues.
Fortunately, severe
hyperstimulation is
rare, occurring in less
than one percent of
treatment cycles. |

Intrauterine
Insemination |
| |
Intrauterine
Insemination is often
an important part of
treatment for couples
that are infertile due
to sperm disorders.
IUI involves injecting
sperm through a narrow
catheter into the wife's
reproductive tract.
For most couples, artificial
insemination is performed
with the husband's sperm.
Depending on the husband's
sperm count and motility,
the wife's cervical
mucus quality at the
fertile time of her
cycle and the estimated
time to egg release
from the ovarian follicle,
a well timed IUI can
be very effective. In
a laboratory, the sperm
can be separated from
the seminal fluid and
resuspended in a very
small volume of sterile
medium that will keep
the sperm alive and
actively mobile. Often,
preparation involves
a "swim-up"
procedure, in which
only the fastest swimmers
are selected for insemination.
The insemination is
performed by passing
a sterile catheter through
the cervical canal into
the uterine cavity and
then injecting the sperm
suspension into the
uterine cavity. Usually
the insemination itself
causes little if any
discomfort. |

In
Vitro Fertilization |
| |
In
vitro fertilization,
or IVF, is a procedure
that involves retrieving
eggs and sperm from
the bodies of the male
and female partners
and placing them together
in a laboratory dish
to enhance fertilization.
Fertilized eggs are
then transferred several
days later into the
female partner's uterus
where implantation and
embryo development will
hopefully occur as in
a normal pregnancy.
IVF is performed by
physicians who specialize
in reproductive medicine
and have received additional
education and training
in the evaluation and
treatment of male and
female infertility.

IVF was originally developed
in the early 1970s to
treat infertility caused
by blocked or damaged
fallopian tubes. By
1978, the first IVF
baby, Louise Brown,
was born in the United
Kingdom. Since then,
the number of IVF procedures
performed each year
has increased and the
success rate has improved
significantly. IVF involves
several different treatment
stages:
|

|
Stage
One |
| |
Ovarian
Stimulation
and Monitoring:
In order to
maximize the
patient's chances
for successful
fertilization,
a patient undergoing
IVF usually
take hormones
in the form
of injections
to increase
the number of
eggs produced
in a given month.
Monitoring is
performed to
continuously
follow a woman's
ovarian response,
allowing the
physician to
adjust and time
medication dosage
appropriately. |
| |
|
|

|
Stage
Two |
| |
Ovum
Retrieval: With
the patient
sedated and
comfortable,
the ova or eggs
are retrieved
through the
vagina under
ultrasound guidance. |
| |
|
|

|
Stage
Three |
| |
Culture
and Fertilization:
The oocytes
are fertilized
with sperm from
the male partner.
At times, the
sperm are put
down on top
of the oocyte.
In other cases,
especially when
there are less
than one million
living sperm,
ICSI or intracytoplasmic
sperm injection
is used catch
a single sperm
and inject it
directly into
the oocyte. |
| |
|
|

|
Stage
Four |
| |
Embryo
Transfer: Either
three or four
of the best
embryos are
transferred
directly into
the uterus and
allowed to implant.
The remaining
healthy embryos
may be cryopreserved
(frozen) The
pregnancy test
is performed
11 days after
embryo transfer.
In a good program
with a high
quality laboratory,
a woman under
the age of 40
should become
pregnant approximately
50% of the time. |

Intracytoplasmic
Sperm Injection (ICSI) |
| |
At
times, there are not
enough normal sperm
to fertilize the eggs
retrieved during an
IVF cycle. Over the
past several years,
embryologists have developed
a technique to catch
a single sperm and inject
it directly into an
egg. Indications for
ICSI include men with
extremely low concentrations
of sperm (less than
6 million motile sperm),
men whose sperm have
failed to fertilize
eggs in previous cycles
of IVF, and men with
complete absence of
sperm (azoospermia)
who need the sperm to
be retrieved directly
from the testicle and
then injected into the
egg. In a good program
with a high quality
laboratory, the success
rate should not be reduced
when ICSI is required.

Embryo
Cryopreservation |
| |
Embryo
cryopreservation is
a method used to preserve
embryos by cooling and
storing them at low
temperatures. The benefit
of embryo cryopreservation
is that it permits the
use of thawed embryos
in an otherwise natural
cycle, sparing the patient
from undergoing ovulation
induction, egg retrieval
and the associated costs.
Unfortunately, nearly
50% of all cryopreserved
embryos do not survive
the freezing and thawing
process intact. There
does not appear to be
any increased risk of
birth defects from cryopreserved
embryos, and there does
not appear to be a maximum
length of time that
the embryos can be stored. |

Ovum
Donation |
| |
More
than 150,000 women in
the United States can't
bear children because
of ovarian problems.
Many women do not produce
eggs, or have had their
ovaries removed, have
had radiation therapy
or chemotherapy for
cancer that destroyed
their ovarian function,
or have dysfunctional
ovaries, and are no
longer producing high
quality eggs. Other
women have deferred
pregnancy until their
late thirties or forties.
Since the ovaries age
at such dramatically
different rates in different
women, while some conceive
quickly, others are
no longer able to conceive
using their own eggs
and require donated
eggs to conceive. Egg
donation is a treatment
that uses the male partner's
sperm to fertilize eggs
donated by an anonymous
female donor, and is
followed by transfer
of the fertilized egg
into the female partner's
uterus.
Egg donors are typically
healthy women between
ages 21 and 31 who have
no known genetic or
sexually transmitted
diseases. They should
be screened for genetic,
hormonal, psychological,
infectious, and physical
diseases. Egg donors
usually take injectable
hormones for eight to
ten days to increase
their egg production.
Donor eggs are retrieved
transvaginally using
an ultrasound to guide
the procedure. The recipient
of the donated eggs
usually takes hormones
to synchronize her cycle
with the donor's cycle
and to prepare her uterus
to receive the embryos
and thus enhance the
likelihood of implantation
occurring. These hormones
include estrogen which
can be taken orally
or administered in patches
that attach to the skin
and progesterone administered
by injections. As in
IVF, three embryos are
normally transferred
to increase the couple's
chances of pregnancy.
In a good program, more
than 50% of ovum recipients
should receive positive
pregnancy tests on their
first attempt. |

Operative
Laparoscopy |
| |
A
fiber optic telescope
called a laparoscope
is inserted into the
Female's abdomen below
the navel to look for
endometriosis, scarring,
adhesions, and other
pelvic disease. At times,
the procedure is performed
to look for the cause
of pelvic pain or infertility,
and is called a "diagnostic"
laparoscopy. Once disease
is identified, however,
the surgeon should be
capable of performing
an "operative"
laparoscopy, and actually
treat the disease. Instruments
such as laser can be
useful in some cases
to treat adhesions and
endometriosis. The primary
advantages of laparoscopy
include rapid patient
recovery (due to the
extremely small incision)
and decreased cost (since
the patient nearly always
goes home the same day).
Aside from the treatment
of extremely large fibroids,
most pelvic surgery
can be performed laparoscopically.

Operative
Hysteroscopy |
| |
If
a uterine abnormality
is suspected following
the hysterosalpingogram,
your doctor may recommend
hysteroscopy. Hysteroscopy
is performed with a
thin telescope, called
a hysteroscope, equipped
with a fiber optic light.
The hysteroscope is
inserted through the
cervix into the uterus
and enables the doctor
to see any uterine abnormalities
or growths. Photographs
or videotape may be
taken for future reference.
This procedure is usually
performed in the early
half of a woman's cycle
so that the build-up
of the endometrium does
not obscure the doctor's
view. This procedure
is usually performed
on an out-patient basis
with moderate sedation
being used. Full recovery
of the patient occurs
within days.

Myomectomy |
| |
Uterine
fibroids are abnormal
growths in the uterus
and almost always are
non-cancerous. Uterine
fibroids are also one
of the most common causes
of infertility in women.
40% of hysterectomies
are performed for the
treatment of uterine
fibroids. New microsurgical
techniques have been
developed to make myomectomy
a choice for some women.
Myomectomy is a surgery
that removes the fibroid
tumor and leaves the
female organs intact.
Reconstruction of the
uterus is often part
of the procedure. Specialists
who perform myomectomies
can discuss whether
or not this is a procedure
to resolve your problem
and whether or not the
procedure can be done
on an outpatient basis.
Medications are another
option for treating
fibroid tumors in some
women. Prescription
medications are available
that can shrink the
size of the fibroid
and lessen heavy bleeding
and pain. These medications
can be used for a limited
period of time and require
careful monitoring by
a physician.

Preimplantation
Genetic Diagnosis (PGD) |
| |
Preimplantation
Genetic Diagnosis (PGD)
is an advanced genetic
technique which allows
an individual embryo
to be analyzed. PGD
is a recommended procedure
for patients who are
carriers of a genetic
anomaly or are affected
by a genetic condition
that drastically reduces
the probability of passing
the anomaly to their
offspring. Additionally,
some patients with advanced
maternal age or a history
of recurrent miscarriages
use PGD to select embryos
that do not possess
chromosomal abnormalities.
The technique of PGD
involves the removal
and analysis of a limited
number of cells from
a developing embryo.
The analysis of these
cells may be performed
by fluorescent in
situ hybridization (FISH)
or polymerase chain
reaction (PCR),
which allows a geneticist
to provide information
on the individual embryo's
chromosomal make-up.
PGD cases require extended
embryo culture (see
Blastocyst transfer
and culture)
to allow for enough
time for genetic analysis
to be performed. In
consultation with the
patient's physician
and embryology laboratory,
the decision of which
embryo(s) and how many
embryos to transfer
will be made. |

Blastocyst
transfer and culture |
| |
A
Blastocyst is an embryo
that has developed two
different cell types and
also contains a central
fluid-filled cavity. The
outer cells, called the
trophectoderm, will become
the placenta, and the
inner cells will become
the fetus. Blastocyst
formation in the human
usually occurs on the
5th day after fertilization.
By the end of the sixth
day, healthy blastocyst
should hatch from its
outer shell (the zona
pellucida), and within
another 24 hours the hatched
blastocyst begins to implant
in the lining of the mother's
uterus.
Over the first two decades
of experience with in
vitro fertilization, embryos
were routinely cultured
for two to three days
in the laboratory, and
then transferred to the
uterus. This is quite
different than when embryos
normally enter the uterus
(day 5 or 6). After two
or three days of growth
inside the body embryos
are found in the fallopian
tubes and may not be ready
to enter the uterus. Recently,
laboratory culture conditions
have been improved so
that embryos can develop
to the blastocyst stage
in the laboratory, and
therefore be replaced
into the uterus at the
more "natural"
time, Day 5 or 6 after
fertilization.
The additional benefit
of waiting longer to transfer
embryos is reducing the
number of embryos needed
to be transferred to result
in a viable pregnancy.
By culturing embryos to
the blastocyst stage we
have more opportunity
to choose the healthiest
ones for transfer. So,
optimal pregnancies rates
may be obtained by transferring
fewer embryos and reducing
multiple pregnancy rates. |
