One cycle of in vitro fertilization ...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

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.

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

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

Sometimes checked for the number of chromosomes and even time-lapse photography. # transferred based on age&quality ...Read more

Frozen sperm. Fresh eggs. Both proven donors. Nulligravid 42 yo woman. Odds of conception after et with 3?

Frozen sperm. Fresh eggs. Both proven donors. Nulligravid 42 yo woman. Odds of conception after et with 3?

Very good: The odds are excellent as long as all other aspects of your workup have been negative. Pregnancy rate with 2 embryos can give a 70% chance. Replacing 3 embryos in this situation would not be suggested as long as the egg donor was 21-28. Most donors are not accepted over 30. The risk of triplets is quite high and would cause significant obstetrical issues such as prematurity, decreased fetal size.. ...Read more

IVF egg removal. 32 follicles only 7 eggs retrieved. Did Lupron (leuprolide) trigger and Hcg. Why so few?

IVF egg removal. 32 follicles only 7 eggs retrieved. Did Lupron (leuprolide) trigger and Hcg. Why so few?

Ask your doc: Many possibilities: incorrect timing (too early OR too late) or administration of hCG, bad batch of hCG, surgeon had difficulty with TVA, maybe only 7 mature follicles and the others were mid-to-small...your doctor and your embryology team are only ones who can answer what happened. Good luck with the 7, sounds good! ...Read more
