What causes frozen embryo thawing failure?

Why do: Embryos not thaw successfully? Traditionally many sub-standard embryos have been frozen that probably should not have; these often die in thawing. The usual cause of embryo death in the past with traditional slow-freeze techniques is formation and shattering of ice crystals within the embryo. ...Read more

What are the stages of development of an embryo?

Several: First the egg is fertilized by the sperm and there should be an embryo with genetic material from the sperm and from the eggs (only 2 total sets). The the egg usually divides into 4 cells then 8 cells. The many more cells divide and the genes inside the embryo become activated. The middle of the embryo clears out and a blastocyst forms and when advanced starts to hatch out of its shell. ...Read more

How can I be sure its my embryos they are putting in?

Having Trust: You should be able to trust your physician. However if you need to trust and verify, as reagan would say, then genetic tests would be possible through amniocentesis or after birth. It may even be possible to do genetic testing on the few fetal cells that have been discovered to travel in the mothers blood stream. ...Read more

I'm wondering can the embryo be tested for krabbe disease?

I'm wondering can the embryo be tested for krabbe disease?

Yes, PGD is possible: Krabbe disease results when both parents carry a gene for this disease and a child inherits two abnormal genes, one from each parent. We know which gene is responsible for this disease, so Preimplantation Genetic Diagnosis (PGD) where we test embryos for the disease before replacing disease-free embryos or carriers back into the mother's uterus, should be possible. This is a form of IVF treatment. ...Read more

What is the medical definition of a fetus versus an embryo?

What is the medical definition of a fetus versus an embryo?

After fertilization: An ovum (egg) becomes a single-celled embryo. At later stages it is called a fetus - up until birth. When exactly an embryo becomes a fetus is somewhat arbitrary since development occurs gradually, but often is listed as 8 weeks post fertilization. Embryos look primitive, have incomplete organ development and are sensitive to teratogens; whereas a fetus is generally recognizable as being human. ...Read more

What point is an embryo, fetus, or baby considered a human being in the u.S.?

What point is an embryo, fetus, or baby considered a human being in the u.S.?

Depends: This depends on who you ask. Some have a personal opinion that life begins at conception, some at "reasonable expectation of viability", some at birth. Various states have their own legal definition of status. I don't expect the arguments to be resolved in my lifetime & I doubt there will ever be a consensus on the matter. ...Read more

Hi I just had 2 embryos transferred both 8 cells one was high quality and one good. Are these good embryos do you think?

Discussion: You mention that one was high quality and one was good quality. That is all the information that we have to go on. I would contact your specialist. They can usually tell you the rating scale of each embryo. They can also give you the associated success rates best on each embryo grade. ...Read more

Failed 1st ifv cycle with perfect graded single embryo. All other levels were perfect too. Should I insist on 2 or 3 embryos next (frozen) transfer?

FET: Sorry for the disappointment! According to asrm guidelines (if your actual age is 34) you could be an appropriate candidate for 2-3 embryos. Rather than insisting on a specific number, why don't you 'insist' that your doctor reach an agreement you are both satified with? ...Read more

Hi, we had 2 embryos transferred on day 2. One is 6 cell embryo and other is 2 cell embryo., gud grade Could you please let us know the chances of pg?

Less than 50%: Here in the U.S. we perform either day 3 embryo transfers (ETs) or day 5 embryo transfers. Probably 90+% of the ETs here are day 5. So you having a day 2 ET is a little odd. I would say that the 6 cell embryo gives you a much better chance to conceive than the 2 cell. Also, you're at a very good age for IVF. Still, with these 2 embryos I would estimate your chance at around 40% to conceive. ...Read more

I'm 41 year old. Is it true that my embryos won't be able to withstand freezing? If I had good embryos, should I have a fresh cycle better than frozen?

Advanced age: Unfortunately, older eggs do not fare well compared to younger ones in any aspect of IVF. And whereas frozen embryos lately perform comparably to fresh embryos when young eggs are used, the same cannot be said about older eggs. ...Read more

Signs of embryo implantation?

Signs of embryo implantation?

Implantation bleed: Implantation bleeding happens 6-7 days after ovulation. Ovulation for mos women happens between days 12-16 from the first day of the period, on average 14 days. Therefore implantation bleeding can occur sometime between day 18 at the earliest and 22 at the latest (days 19-20 for most women). Of course there are exceptions but this applies to most regularly menstruating women. ...Read more
