Your Moral
Belief :
At Delhi IVF we absolutely respect
your moral beliefs. Because
of this, we have taken the care
to devise acceptable assisted
conception programs for virtually
all faiths – Christianity (including
the ‘Brethren’), Islamic, Jewish
(including supervised Kosher
treatment cycles), Hindu and
Buddhist. We guarantee that
your egg and your sperm will
never be used in a way that
you have not explicitly or implicitly
consented to.
When does life
start?
There are many views on the
moment that represents the beginning
of a new life. Some people believe
that it is the instant that
the sperm enters the egg, for
others it is the moment that
the genetic material of the
two parents come together (this
happens some time after fertilization
and is called syngamy), while
others again place it at certain
developmental milestones of
the embryo or fetus, such as
implantation, nervous system
development or “sentience”.
Because
of these questions, some people
face a moral dilemma when considering
cryostorage (freezing) of embryos
after an IVF cycle. Embryos
are often cryostored if there
are more produced than are necessary
for a single embryo transfer.
It enables a number of embryo
transfers while stimulating
the ovaries with hormones only
once.
For many people, this option
is very attractive, since it
is the ovarian stimulation that
is the most expensive and complicated
part of an IVF cycle. But it
does mean that there are often
embryos produced that will never
be transferred. For some people
this is not a morally acceptable
situation.
Syngamy
Syngamy literally means “married
together” and is the moment
when the genetic material from
the egg and the sperm join to
become one. It occurs in the
fertilized egg about 20 hours
after the sperm has entered.
A few hours before syngamy the
sperm’s chromosomes and the
egg’s chromosomes are visible
as separate ‘spheres’ (or vacuoles)
called pronuclei.
At this stage
we
know the egg has been successfully
fertilized
the male and female genetic
material have not yet combined the
zygote (as it’s called) can
be transferred to the fallopian
tube (by
laparoscopy or vaginally, by
ultrasound-guided catheter) the
fertilized, pre-syngamy egg
can be ‘frozen’ (cryostored)
for a later decision on its
transfer or dissolution (i.e.
allowing it to dissolve away).
What are the special
options and alternatives?
To provide sperm without masturbation,
semen can be collected in a
non-
sperm-toxic silastic condom
during sexual intercourse. These
special condoms are available
from Delhi IVF.
To avoid any manipulation of
eggs outside the body, consider
IUI intrauterine
insemination of prepared sperm
at ovulation, which can be stimulated
to
produce multiple follicles (although
with a chance of high multiple
pregnancy,
such as triplets).
To
avoid fertilization outside
the body, consider GIFT – gamete
intrafallopian transfer, in
which unfertilized eggs are
transferred with separate sperm
into the fallopian tube at laparoscopy.
To
avoid producing more eggs than
will be used, consider natural
cycle IVF (without ovarian stimulation,
but with in vitro fertilization).
To avoid producing more fertilized
eggs than will be used, we can
fertilize just two or three
recovered eggs after stimulation.
To
avoid producing more embryos
than will be used yet still
have the medical benefit of
freezing fertilized eggs that
have not yet become embryos,
we can
freeze extra fertilized eggs
before syngamy.
