Who is a good
candidate?
When considering the feasibility
of cryopreserving her unfertilized eggs, a woman needs to
initially determine her suitability for this process by checking
her hormones (FSH, LH, and Estradiol) on the second or third
day of her menstrual cycle. At the same time a vaginal ultrasound
is performed in order to document that a good supply of eggs
are present in her ovaries. Screening for HIV-1, HIV-2, HTLV,
Hepatitis A, B, and C is required by the New York State Department
of Health.
When a woman is deemed to
be a good candidate to produce a sufficient quantity of eggs
for cryopreservation, her ovaries can be stimulated with injectable
fertility medications in a similar manner to that utilized
for In-Vitro Fertilization procedures. Egg follicle development
is monitored with ultrasound measurement of ovarian follicles
and estradiol levels. When the follicles are mature, another
hormone, HCG, is administered to complete the maturation process.
The eggs are harvested 36 hours thereafter, using ultrasound
guided transvaginal aspiration, with conscious sedation. The
procedure usually takes between 5 and 10 minutes of actual
operating time and is usually well tolerated. Mature oocytes
are then cryopreserved and stored in liquid nitrogen.
Where will oocytes
be stored?
Cryopreserved oocytes will
be stored in a New York State approved long-term cryopreservation
