YoY - February 6

Dear Doctor,
I am 31 year old with good health. My FSH is 3.3. I need to do IVF because my husband sperm blockage. I just fail on my first IVF in Dec 2006. I responded well to the stimulation regime with eight oocytes being retrieved from the eight follocles aspirated. Six were at metaphase 2 and so injected (ICSI)and five showed normal fertilisation. I replaced one excellent quality embryo onday 3, but sadly I was not pregnant. The four spare embryos were not suiable for cryopreservation and showed a lot of vacuoles. I planned to try the 2nd ivf in Jan 2007. So I very need you the professional doctors help please.
Question #1: Why the embryo were not became Blastocyst?
Question #2: Why the embryo showed a lot of vacuoles? How to improve the egg quality?
Question #3: What can I do to make the 2nd ivf
sucessful? Thanks a lot for your help.

Only 1/3 to maybe 1/2 the eggs a woman makes are capable of successful pregnancy. Genes from the sperm do not play a role in embryo growth until after day 3. Not all sperm are capable of a successful pregnancy, either. Also, not all laboratories can reliably grow blastocysts. I do not know the reason for your husband's blockage, but if it is congenital, he has a variant of cystic fibrosis until proven otherwise. You shoould be checked for carrier status. You do not want to have a sick child.
Good luck.

Thanks Dr. Jacobs,

My husband's blockage is not congenital. He is healthy. Do you know why there are embryos showed a lot of vacuoles?

Thanks!

There are 3 possibilities. First is a problem with the eggs. Second is a problem with sperm. Genes from the sper do not play a role in embryo developement until after day 3. Third is a possible problem in the lab.
Good luck.

Dear Dr Jacobs,
I got the egg collection yesterday. We got 16 eggs. 13 mature oocytes had sperm microinjection (ICSI) of which 7 showed normal fertilisation. Are the number for fertilisation normal?
Thanks for your help.

That is a reasonable fertilization rate for severe male factor problems.
Good luck.

Many thanks Dr Jacobs,
On day 3 only 2 embryos left, but 1 embryo is 8 cell with vacuoles and the other one is 6 cell good looking embryo. Dr. what do you think the chance to success in this time? Many thanks you always be here with us.

It is hard to know how significant the vacuoles are. There is certainly a chance for pregnancy.
Good luck.
