IVF Process
Step One - Ovarian Downregulation
Pituitary
gland, which is close to
the front of your brain, is responsible for the normal functioning of your
ovaries.
Suppressing
the pituitary gland not only helps in achieving
optimum ovarian stimulation, but most importantly it stops your ovaries from releasing premature eggs.
Ovarian
downregulation is particularly helpful for women who respond poorly, or not at
all, to the ovarian stimulating medications and therefore cannot take the full
advantage of the IVF treatment.
Step Two - Ovarian stimulation
Infertility medications like
gonadotropins will be used to stimulate the growth of the follicles and eggs
which will be retrieved for IVF procedure.
Step One - Ovarian Downregulation
This is a preparation procedure that uses
medications, such as Gonadotropin-releasing hormone
(GnRH) agonist or GnRH antagonist to temporarily ‘switch off’ the messages
going from the brain (pituitary gland) to the ovaries telling them to produce
an egg on a monthly basis.
Step Two - Ovarian stimulation
This involves stimulating the development
and the release of eggs using various infertility medications.
Your doctor will monitor you frequently
during this time to make sure your follicles are developing properly and to
identify the right time for egg retrieval. Once your follicles are developed,
your doctor will retrieve the mature eggs.
What does it involve?
Your treatment will depend
on your specify needs but it generally include following pathway:
Are there any restrictions of using hCG injection?
Sometimes hCG injection may be stopped because:
Sometimes hCG injection may be stopped because:
·
A lack of mature eggs for
the IVF procedure such that the follicles may not have developed properly
·
Woman ovulates prematurely
and the eggs cannot be retrieved
·
Woman develops too many
follicles and doctor feels that it would be unsafe to give the hCG injection.
How long is ovarian
stimulation?
It can be a lengthy process
with a lot of your time devoting to attending appointments with your doctor and
taking your medications at the right time. The length of ovarian stimulation
will depend on your ovarian response during the treatment.
