Hi Mara
The chances with aspirate are very good if your clinic is experienced in the technique. If DH has kids already then the chances are very good I understand. We have been recommended TESE exactly because our prof hopes the sperm quality be higher than in the ejaculate. What we HAVE decided to do, and some might call this a bit over the top, is have PGD (pre-implantaion genetic diagnosis) just incase of abnormalities but this is more due to dh age (48) as well as the possibility of high level of superficially normal sperm that actually are not normal...because that was what was found in the ejaculate.
I am using donor eggs, so we have our TESE samples frozen and IF the test results are OK we will ship them from here (Germany) to our clinic (Ukraine) - dn't ask - it's dead complicated

so my cycle is not affected atall. On the other hand the clinic in Ukraine want to do a fresh TESE anyway, and use the frozen ones as "back-up" if all works out. I understand this doesn't affect the cycle timing atall (It will affect dh willingness to walk around Kiev though

)
It's all speculation though, until we get a result on the TESE sample (we know there were lots of sperm under normal microscopy, the prof has special techniques in his research programme to show more detail, he embeds the sperm in resin and then slices and photographs them under electron microscopy, claims he is the only one in Germany to do this)..then we don't know what's going on..
It's nice to find someone in the same boat, keep up the PMA, I am sure you'll be fine, and dh will be able to give you some lovely wigglies.
big hug
