jeb8303 - I don't know much about LH. Generally my levels slowly drop during the stim phase. With 2 days of luveris injections mine went up from 1.1 on Monday to 1.9 today (at the start of this cycle it was at 2.2 or 2.4 or something like that). This is the first cycle I've used luveris. The FN said they like LH to remain above 1, so you're not down there yet.
LH is normally stored in your pituitary until you dump a whole lot of it into your body at once to trigger ovulation. Synarel empties the pituitary twice a day so you can't store up a big LH surge, therefore you won't ovulate on your own but will use a trigger injection before EPU. I wouldn't go drawing any conclusions about LH deficiency while you're deliberately tampering with it's level.
On a previous cycle (which prompted my FS to include low-dose Pregnyl in my protocols) my LH got down to 0.5-0.6 or thereabouts. I asked the Prof if low LH is a cause or effect of having bad eggs and he said they didn't know enough about it to say.
