Wow, you ladies are busy in here - I turn my back for a moment and you're yakking away like crazy, aren't you?

Yeah, I guess I should've learnt the traits of the fairer sex by now!
Sita. Very sorry to hear your news and although I can't possibly know what it's like to go through M/C (I'm a bloke!) I do know how it feels to be denied - albeit from a slightly different perspective. I wish you all the best and would advise you to "stick at it" and "keep your chin up" although I'm sure you've heard them before. Regardless, listen to the words and never lose faith.
Jovigal. Many congratualtions on your test results! As they say here in Germany - I'm pressing my thumbs for you! (It means, my fingers are crossed!!!

)
beachbaby. A hug for you - if you're allowed to accept them from another bloke?! Our 2 ICSIs have failed with the embryo failing to implant and we still haven't been given any reason as to why - so I can appreciate how you're feeling. I'm wondering if it's a lack of Progesterone?
Here's my "bloke" understanding and perception (very much in
laymans terms) - for what it's worth . . .
When a woman gets pregnant, the body releases Progesterone to "tell" the uterus not to let the endometrium "flush away" and thus provide a decent "bed" for the embryo to make it's nest in.
With IVF & ICSI - the body doesn't "know" it's going to be pregnant so this extra Progesterone has to be provided. On both ICSIs, my wife was given suppositories of 400mg Progesterone to use. This was done
after transfer - again, for both ICSIs.
What I am wondering (and if any of you can help me here, I'd be more than grateful) is . . .
1. Is a daily dose of 400mg of Progesterone actually enough? Surely each individual body reacts differently and whilst the
average may be that 400mg is indeed sufficient - what if in the case of my wife, it isn't and she simply needs more to tell her body not to get rid of the endometrium? I can't get an answer from Hammersmith on this - from them it's a case of, "That's how we do it," and there's no discussing it.
2. Isn't it leaving it a little late to begin taking the Progesterone supplements on the day of transfer? To my (simple, male) mind it would make more sense to start this at a lower dosage a little earlier (perhaps on the day of collection?) so that the body starts to build up a more natural Progesterone level? Whilst I will freely admit that my knowledge of female biology is quite limited, I feel pretty sure that during a natural pregnancy, the Progesterone "switch" doesn't suddenly "flick on" and pump out a daily dosage of 400mg . . . does it?
Anyway - there's a couple of questions I have been pondering over and perhaps some of you may be able to shed some light for me?
In the mean time . . . take care of yourselves and I'm going to take this opportunity to wish
you all a very
HAPPY and
SUCCESSFUL NEW YEAR!!!
Best Regards
