Ivf (Definition)

In vitro fertilization is an assisted reproductive technology. Ivf is a procedure used to treat fertility problems and assist with the conception of a child. During ivf mature eggs are retrieved from the ovaries and fertilized by sperm in a lab. A few days later, the fertilized egg (embryo) or eggs are implanted into the uterus. One cycle of in vitro fertilization ...Read more

How many days after fertilization does the fertilized egg become a blastocyst? Then embryo? What implants-the blastocyst or embryo?

How many days after fertilization does the fertilized egg become a blastocyst? Then embryo? What implants-the blastocyst or embryo?

The process: As the fertilized egg divides, it is first known as a morula. Approximately 5 days from first fertilization it forms into a hollow ball known as a blastocyst. This blastocyst implants and begins to sort itself out into different layers--the inner group becomes the embryo and the outer layer will work to nourish and protect. At approximately 6-7 weeks from time of fertilization, an embryo begins. ...Read more

How does IVF "egg donor" process work?

How does IVF "egg donor" process work?

Overview here ...: First you choose either an anonymous egg donor (usually under 30) or a known donor. The donor is tested for egg supply, infections, genetic or psychological issues. When you are ready, the donor receives shots to make multiple eggs then has eggs removed. The eggs are fertilized in the lab with your partner's sperm, grow into embryos, and the best 1-2 embryos are replaced. Any extras can be frozen. ...Read more

Is adoption better than ovum donor baby?

Is adoption better than ovum donor baby?

Adoption: This is a value judgement, of course, adoption is a wonderufl thing. A baby who is already born and needing parents finds loving parents to live with. While time consuming and at tmes expensive, adoption is not complicated. Having a ovum donor baby is complicated and usually expensive, and carries the inherent risk of failure (much greater than adoption). When it works, it's wonderful too! ...Read more

Are pgd and ivf(in vitro fertilization) the same thing?

Are pgd and ivf(in vitro fertilization) the same thing?

No but related : Ivf refers to the procedures we use the remove the eggs from your body, fertilize them in a laboratory and transfer them back into the uterus. Pgd refers to testing those embryos for genetic abnormalities before we return them back to your womb. Most ivf is done without pgd but pgd cannot be done without ivf. ...Read more

40yrs.Old, pcos, 1st IVF cycle w/genetic testing. Four day 5 embryos - all chromosomally abnormal. Worth another try? 39 eggs were retrieved, 19 fert.

40yrs.Old, pcos, 1st IVF cycle w/genetic testing. Four day 5 embryos - all chromosomally abnormal. Worth another try? 39 eggs were retrieved, 19 fert.

Talk to the prenatal: Genetic counselor at the fertility clinic. Age-related odds are greater than 50% that each of your embryos has aneuploidy, an abnormal number of chromosomes, many of which either won't implant or wion't be carried to term. Age-related risk of having a child with autistic spectrum disorder is also high. Discuss options with your tac doctor to make an informed decision. It's a personal choice. ...Read more

Does fertilization finish before the conceive date of pregnancy?

Does fertilization finish before the conceive date of pregnancy?

Yes: Fertilization is conception. Therefore, a woman whose egg has finished being fertilized has finished conceiving. She has a one-celled "baby" which is just a fertilized egg. It splits into 2 cells, then 4 cells, then 8 cells, etc... No woman knows exactly when she conceives, in a natural pregnancy. How would she know? She can neither see it or feel it. Conception dates are therefore only estimates. ...Read more

How much time/days are required for paternal genome and blastocyst development after embryo transfer?

What?: I'm not sure what your question is. 1. If you had a day 3 embryo transfer it will be a blastocyst in 2 days. If you had a day 5 transfer it is already a blastocyst. 2. Paternal genome is working from day one of combination of the two genomes. The dominant genes regardless of maternal or paternal origin take the lead. Sex development is initiated near the 9th week. ...Read more

What are the causes for failed embryo implantation after embryo transfer?

Probabilities: A high proportion of natural embryos do not implant, the same is true for IVF/embryo transfer. Rates improve with pre-screening of the developing embryos, and with younger age of donor (40 have similar rates with donor eggs, very low rates with their own eggs. ...Read more
