Hello,
My wife recently completed an ivf cycle at a fertility clinic downtown toronto. Unfortunately it was unsuccessful 
Our problems with fertility stems from myself. I was diagnosed with obstructive azoospermia requiring a microtese procedure. After the procedure was completed the sperm was transported from the hospital to the IVF clinic where it was frozen.
When it came time for fertilization, the sperm did not survive the thawing and we were only able to fertilize 3 eggs which failed to get my wife pregnant. 2 embyros reached to 8 cell and 7 cells--those were implanted on day 3. The 3rd was a 5-cell embryo which we decided to wait to see if it will survive until day 5 then we would freeze--unfortunately it didn't survive.
My wife had 33 eggs retrieved of which 17 were eligible for fertilization using ICSI however I was told that after the thawing, only a few sperm were moving but the rest didn't make it. They injected all the eggs with the hope that some will make it but as I said before, only 3 fertilized.
Is this normal for sperm retrieved via mirco tese not to survive thawing? I wish this was explained to me prior to pursuing IVF...we were left devastated that with so many healthy eggs, none made it. Is freezing an issue for sperm retrieved via micro tese?
Any information is greatly appreciated. My wife does not wish to proceed with any further IVF treatments and I am trying to figure out what went wrong.
My DH has a similar issue. I haven't been able to get to the Egg retrieval stage yet but when I met with the embroyologist he mentioned that My husband may need to have the TESE performed again the day of the retrieval depending on how the sperm thaw out. Were you given this option? I would think if not many sperm thawed and you had such a large number of eggs that another fresh TESE would increase your odds.
I am already worried that his sperm will not fertilize my eggs..they had mentioned a donor sperm for me...but the only reason we are doing IVF is so we can have a biological child together.
Sorry to hear the process didn't work. I would think if you were to try again in the future to go with a fresh sample done the same day as the retrieval..now that you kow that you have some sperm.
Good luck and sorry the process didn't work for you both.
