MFI experiment...inconclusive so far

For those of you that remember, we were doing a MFI experiment for IUI #5.  Jeff was instructed to expell either from masterbation or sex every.single.day. from cd4 until trigger, then take a night off and then have IUI.  There was an Australian study, and a few minor follow ups that say this makes the sample from MFI'ers have the best chance of pregnancy rates, mainly from motility and morph.  I was very fearful of doing this because what if it hurt instead of helped?  

Well, the good news is it didn't hurt, (but I'm not sure it helped either).  His post wash was almost identical to his sample in January when we got PG and m/c (which was his best sample to date) - post wash over just over 10mil/ml with 88% motility.  HOWEVER his initial numbers were lower (18mil/ml vs 36mil/ml).  So, that means that many more made it to post wash.  In January, less than third survived to post wash whereas this time over 50% made it.  IDK.  As my mother would say, six of one half a dozen of the other when they both ended with about the same amount.  Since the final number was the same and the post wash motility was the same I don't know if his initial count was hurt because of the experiment or if it's just a basic fluke lower sample (how MFI can be).   And the higher motility and survival rate to post wash...was that because of this? IDK.  

What I can say, is that it wore my poor 41 year old husband out!  We had sex the night of trigger, but it took some effort on our parts to get it done if ya know what I mean...because of eight straight days.  But the job got done.  Was fairly unromantic though from the effort that had to be made.  Then last night after having given his sample in the morning and to have to have sex that night?  Ugh, we tried.  For like, an hour.  But eventually just gave up, and then he felt bad and said it was - "just too much"  and  "forced".  

Now, we've had timed sex for over three years.  And this is our fifth IUI.  This ain't our first time to this rodeo.  It's never felt forced.  It's never been so difficult.  It's never been so unromantic.  I've always felt blessed that as an MFI couple, we've never had these issues.  Last night just sucked.  A Lot.  So, if this cycle doesn't work I don't know that we'll be willing to try that again.  I hated seeing DH so disappointed in himself.   I hated that I couldn't help but have a few tears stream down my face.  And that I couldn't find the words to explain to Jeff that the tears were not because it didn't happen, but because of seeing his face.  I don't want him to feel bad.  THAT is what was making me sad.  I hate IF.  I really, really do.
