Trigger.. What trigger did you have and did you have many immature eggs at EC

I have triggered with ovidrel 2 times and had 3 immature eggs first time and 5 second time.
Just wondering what triggers you had and have you had more success with different ones
(I was successful with icsi with ovidrel but no frozen as such few to fertilise)

I had pregnyl and got 4 eggs (I have low AMH and only had 4 follicles) they were all mature and all fertilised x

All 3 IVF triggers were Ovidrel. First IVF, only two mature follicles and Dr forgot to collect one of them! So only one egg which was mature and fertilised. Second IVF, 5 eggs of which 4 mature. Third IVF, 6 eggs of which 3 mature.

Can I ask how many eggs you got in total each time?

I am not sure that it is the trigger that is primarily responsible for the egg maturation, but more the size of the follicle. For example with my last IVF, I knew that 3 follicles were smaller and was surprised that they got an egg from them, so it wasn't surprising when of my 6 were immature.

Just want to share this with you that I found on the internet if it is of any reassurance or help to you:

Increased success rates have been shown where the batch of eggs collected included at least 1 or 2 immature eggs. Where there were no immature eggs, it may be a sign that stimulation was continued for too long and many of the eggs may be atresic (over mature). Immature eggs can sometimes be fertilisable by IVF but not by ICSI. So if there are suffficient sperm, it may be worth asking for IVF to be attempted on any immature eggs even if the main plan is to ICSI.

PS Lauren, nice to see you around. I think of you as I feel for you in your circumstances and am amazed by your strength and positivity. Have you got that elusive letter in the mail?

Hi Shell

How are you? Sorry not kept in touch much, yes its all systems go, funding approved, huge pack of info to fill in which we did and posted back to Care last week then yesterday a consultation letter arrived we go on 21st March smile there's no wait for donor eggs treatment either, getting nervous now xx

Wow, so it's all systems go! I am doing another IVF cycle in March. To be honest, you actually had much better results than me with your IVF so I don't know if I am living in denial but I just keep reading and researching (and stressing and hoping!). So lets hope we both finally get some good news.

I think egg maturity has more to do with the timing of EC than the content of the trigger.

I used ovitrille. I had low egg numbers due to doing natural/ low stimulation ivf. Over 4 rounds 10 eggs were collected and one was immature.

Reading about it the trigger is what makes the egg separate from the follicle (even for ivf ) otherwise it can get stuck to follicle at collection and empty follicles. It also causes meiosis (the egg shedding half its dna to 23 chromosomes)
My friend has just done a cycle with what looks a real improvement same number of eggs 10 about same fert but last time lots didnt make it on the third day down to 2. This time with pregnyl they had 4 very good and 5 altogether.
It may not be that as could be anything. But the consultant has switched to it as he thinks he is getting better results.

I agree though it possible mine were immature as too small (i had wanted to stim longer to get more than the 8 they saw due to low fert rates last time and also had stimmed 2 days less so not surprisibg more were immature. What i dont know is whether last time most were overripe and thats why they didnt fertilise)
We will have to wait and see

Naty, how are you holding up? You sound fine, offering logical advice to others on here while you wait. I would be rambling away about my every little twinge! You will seriously have to offer me some advice as to how you keep yourself sane thoughout IVF. Whatever you do obviously works as your first IVF produced your first child. Here's hoping it works for your second. So I take it you still have avoided testing then.
