Hester & Sweetfudge,
About inseminations - we used info from PinkParents -was very clear and even included the syringe. Our donor's wife got some little NHS pots (they assure us the logistics at their end were quite funny) - small clear plastic ones with silver screw on lids and we just kept it at body temperature (in hands, or between legs) until we used it. But its been quite cold, and a few times at 'pick up' we've stopped and chatted so its been cold. Although the time it worked we were quite quick. So that seemed fine. Also had the terrifying worry about 'leakage' (sorry if tmi), but that didn't seem to matter - I kept reading message boards about that to reassure me it was okay. We used the 10 ml syringe from PinkParents, until the time where we lost it 5 mins before setting off for collection! On a Sunday, as well. Ended up in an NHS walk in centre - frightened a receptionist by saying I wanted a syringe you could use to feed a baby (I think cos of the child protection worries they then rushed me in to see a nurse!), had to explain our situation in a hurry, and the wonderful woman came up with about 12 different ones, so in the end we used a 5 ml one, cos it was more comfy. So just found a quiet spot, hid under a blanket in the backseat, it took all of 2 seconds and then stayed lying down for the journey (about 40 mins). With the obligatory pillow.
On the zinc thing, it may or may not have helped with him, but I also made sure we were having lots, not in supplements but in diet. Also found some sprouting sunflower seeds (health shops) as someone said they were miraculous - put them in salads.
I do really empathise with your fears about the donor getting fed up. Despite us knowing on the one hand that he and his wife were really supportive, our true fears always came out - when I got a text in the hour before we were due there, we both jumped, fearing it would be a change of mind. We also kept reassuring them that they could pull out, silently hoping that wouldn't happen, cos it was so important they both felt good about it.
I don't know that we did anything special for it to work, I'm sure that its all down to luck in the end (I've had people saying - you must have been less stressed than DP - absolute rubbish, I was on internet everyday driving myself mad - don't believe in the stress thing making it harder. Wish there was a magic trick, but someone would have found it. Do try the sprouting seeds though (good with grated carrot, cheese, celery etc.), cos a friend recommended it who had had difficulty ttc. Look after yourselves
What a long post!
