Frozen eggs for IVF resulted in fewer successful pregnancies
American Society for Reproductive Medicine has
published results of a new study conducted in order to compare success rates of
IVF cycles with the use of fresh and frozen oocytes. The research team
investigated outcomes of the two IVF techniques during the year.
Results of the study confirmed previous comments made
by the reproductive medicine community representatives with regards to the eggs
cryopreservation: “Although analysis of literature shows that cryopreservation
technique is effective for women who need it for medical reasons we cannot use
it widely to plan pregnancy".
Recent studies have shown that only 34% of 12,000 IVF
cycles with frozen donor eggs ended in a successful pregnancy. While 79% of
programs with fresh oocytes resulted in normal pregnancy and live birth.
Scientists note that the main reason for failure results
of IVF programs with frozen biological material is poor quality of cells after their
thawing. Carrying out numerous experiments and researches, experts explain:
"IVF with cryopreserved eggs resulted in fewer live births. It’s much
better to use fresh oocytes in order to reach successful pregnancy and live
birth. During cells’ thawing their structure is damaged. In addition not many
cells survive. Doctor can even not to see deformation of cells immediately, but
in future it could lead to various diseases and abnormalities of child".
Women who freeze their own eggs in order to postpone
fertility “are generally not infertile, but most are not as young/healthy as
carefully screened egg donors,” expert explained, so he would anticipate
pregnancy rates among women who freeze their own eggs to “depend largely on
their age, health, the number and quality of eggs frozen, and the quality of
the IVF center/lab where the procedure takes place.”
In recent years, an increasing number of women have
used donated eggs for IVF. Donor eggs’ popularity has been growing from year to
year. Many European countries buy donor cells in Ukraine to carry out IVF
programs at home. Ukraine is recognized as one of the best donor cells producer,
because there this procedure is legal and there is a low living standards in
Ukraine. Egg donation programs make thousands of young, healthy women possible
to sell clinics own qualitative cells for infertile couples from Europe.
2ww is the most dreadful part of treatment indeed. What I know for sure is that 4-6 days is too early for testing being through IVF. Some REs even suggest it to be more than 14 days, I guess with a purpose. This is absolutely normal you feel stressed and nervous about the waiting. I should say everyone feels the same as 2ww is not a joy. Know it pretty well. In my case we were using donor eggs with IVF in Ukrainian clinic. Transferred 2 nice 5-day blasts. Being 1.2 weeks after transfer I felt so much tired of “not knowing” that was on the edge of doing the home test. But my husband stopped me saying that was not the right time and that I knew myself it was early. So further did nothing just waited for the official testing.
ReplyDeleteAs for the symptoms I felt almost nothing for 1.5 weeks, but then seems all they burst out.
I'd been having lots of stomach pain. Sharp twinges on both sides, dull aches, heaviness. Lots of muscle pulling pain when I get up suddenly. Some cramping but not too much. Been going on a few days but it was pretty frequent. I was also dealing with nausea and dizziness. No bleeding, spotting. Got BFP!!
Be strong, hun, do not be worried about lack of symptoms, probably it’s not the time yet. I’ll have my fingers crossed for you XX
I've been through failed IUI, ICSI attempts. dh's semen is low count and motility. My eggs of no use for ivf, so we went straight onto egg donation. So in our case that was the route leading us to a wonderful baby boy.
ReplyDeleteHere are some of the pros of ivf. IVF is the oldest ART procedure on the block. IVF has been used long enough for researchers to have done extended health studies on the children conceived using this method. So far, no medical problems have been directly linked to the procedure. No link to cancer. Recent studies have shown no connection between ovulation-inducing fertility drugs and cancer. (Early studies suggested that exposure to fertility drugs might lead to a higher risk of ovarian cancer or other cancers of the female reproductive system.) Improved techniques. For example, advances in embryo cryopreservation (freezing) have resulted in IVF pregnancy rates that are about the same for frozen and fresh embryos.
Though the outcomes of IVF vary dramatically, depending on each couple's reasons for infertility and their ages. The percentage of IVF cycles resulting in a live birth (in which one or more babies are born) is the following:
40 percent for women age 34 and under
31- age 35 to 37
21 - age 38 to 40
11 - age 41 to 42
5 - age 43 and over
Unfortunately time never plays on our side..
People who have no idea about how it feels have no right to judge. I suppose you need these issues to be discussed with your dh. Share your thoughts. Get the most of his support.
ReplyDeleteOur fertility journey was long though I never paid too much attention to what others think. The only thing which drove me mad was seeing prego women. I felt really jealous...
I have endo, severe. Married for 10 years, 2 of which - ttc. tried IUI, ICSI with oe. Then 3 rounds ivf with de. Only the 3rd one successful. Noone can imagine the pain we have to go through to be finally blessed. And this is out of the question about morality or sth when it comes to term of no being able to have a baby. Our greatest natural right cannot be judged by unknowing ones. And as far as you have chances to have your baby - do it!!
