IVF - In Vitro Fertilization is a last
resort for many couples. Most couples starting IVF have
already been through long months of trying to conceive
naturally, failed IUI
- Intra Uterine Insemination - cycles, multiple
tests, a lot of frustration and disappointment.

What
is IVF?
In Vitro Fertilization (literally, fertilization
in glass) is a procedure during which the egg, instead
of being fertilized in the woman's fallopian tube, is
fertilized in a test tube or petri dish. When minimal
sperm is available, frequently ICSI
- intracytoplasmic sperm injection - is performed.
How is IVF
performed - what's the process?
Step 1 - Preparation
Both partners go through a variety of tests. These vary
from one medical center to another, but often include
hormone tests for the woman, AIDS and other tests for
both partners and a sperm
analysis for the man.
The medical center decides on a treatment
plan -- how the egg production will be stimulated in
the woman and when it will begin (on what day of the
woman's cycle). This is what is referred to as your
IVF protocol.
Frequently Lupron (also known as decapeptyl)
is used to help the doctors take full charge of your
hormones. It depresses your natural hormones, making
the medication the sole source of ovarian stimulation.
Egg production is stimulated using hormones
(e.g. Pergonal, Repronex, Fertinex, Follistim, Gonal
F, Novarel, Ovidrel, Pregnyl, Profasi, and Menogon and
Puregon), with the goal being to produce a "good"
number of eggs to help increase the chances of having
several viable embryos. (Good is defined differently
in different medical centers). When too many follicles
begin to ripen simultaneously, it raises the risk for
OHSS (ovarian hyperstimulation syndrome).
The stimulation of egg production takes
anywhere from several days to close to two weeks. During
this time the woman is monitored closely using ultrasound
and blood tests. It is very common to make changes to
the IVF protocol during the stimulation process.
What you feel: You may
feel swollen or bloated from the multiple follicles
that are growing. You may feel irritable or have other
symptoms as a result of the hormone injections and you
may feel anxious about the egg retrieval process and
the success of your cycle. Many clinics now offer support
groups for their patients.
Step 2 - Ova or Egg Aspiration
/ Retrieval
Once the eggs are ready, they are aspirated or retrieved
using a needle that goes through the vaginal wall and
into each follicle.
This procedure is generally performed
using light general anesthesia. It usually takes less
than an hour from the beginning of the preparation until
the woman wakes up from the anesthesia.
What you feel: After
the procedure, you may feel some discomfort and you
may continue to feel bloated. If you feel any significant
pain or change in your general feeling, it is important
to report them to your doctor or medical center.
The man is asked to give a sperm sample.
He may be asked to come in with it in the morning or
may be ushered to a private room... (see information
about giving
a sperm sample)
Step 3 - Fertilization
The lab evaluates the ova and the sperm and decides
how to proceed. The end result is hopefully embryos.
Depending on the local policy, you may
have information about the number of embryos as early
as the following morning.
If the protocol calls for ICSI - Intracytoplasmic
Sperm Injection - it is perfomed at this time. ICSI
is generally used in cases where the sperm quality is
very poor and fertilization would not occur naturally,
such as in cases of poor (or lack of) motility. An individual
sperm is selected and injected into the egg.
The initial fertilization rate is not
always the number of embryos that will be available
for transfer. Some eggs fertilize and then do not continue
to divide properly. Depending on the decisions made
at your particular medical center, only embryos of a
certain quality level are recommended for transfer.
Step 4 - Embryo Transfer
Once the embryos are formed and have started to grow,
it's time to put them where they belong - in the uterus.
One or more embryos are transferred to
the woman's uterus using a catheter. The process is
similar to IUI
(intra-uterine insemination) and is usually painless.
You may be asked to empty your bladder before embryo
transfer. You may also be offered photos of your embryos.
Step 5 - Waiting
Maybe one of the hardest parts of the whole process.
The two-week wait. It might only be two weeks, but it
seems like at least 2 months.
Support in the form of progesterone suppositories
or injections may be given. This helps keep the progesterone
levels high, to increase the chance of a pregnancy being
established.

pregnancy signs and symptoms for more information.

IVM - In Vitro
Egg Maturation
A variation of IVF in which the procedure
of stimulating egg production is reduced to approximately
three days. The ova are harvested when they are not
yet matured & are then matured in a laboratory.
This method is not widely accepted and
is recommended particularly for women who suffer from
PCOS - polycystic
ovarian syndrome - and are at higher risk for OHSS
- ovarian
hyperstimulation syndrome.
Also see my blog
entry about IVM.
Frozen Embryo Transfer
When excess embryos are not transferred,
they can be frozen for future cycles.
In a Frozen Embryo Transfer cycle, the
uterine lining may be prepared using hormones or the
transfer may be performed using a natural cycle.
The embryo(s) is/are thawed and transferred
to the uterus in the same process as step 4 above.
It is said that frozen embryos are less
successful than fresh embryos, however some women who
have been successful with frozen embryos feel that some
factors actually make it more likely to succeed:
- The preparation stage, which is emotionally draining,
is much simpler
- There is no egg retrieval process -- another high-stress
point
