Stored ICSI embryo's and gender

[andi81]

Hi Ladies,

I've had a burning question in my head for a while now but can't seem to find any answers online so i thought I'd throw the question out: just wondering if anyone knows about the gender possibilities of embryo's fertilised and stored at the same time and whether or not they are all more likely to be of the same sex? My DD is the perfect result of our first successful icsi cycle and if we were to have another girl that would be absolutely fine by us but just wondered what the odds were. I have a feeling that when it's icsi the sperm is randomly selected as oppose to IVF where it relies more on the natural process ie. the speed of the sperm (which can obviously effect gender).

Anyway, jsut throwing it out there.

Interesting! Our first ICSI gave us a girl and we have one frosty. But I thought that ICSI babies were more likely male?

Sorry no answers but subbing as im curious about the same thing

I'd be interested to know also. I have a ICSI FET DD already and am pregnant with number 2 from the same batch. We are hoping to find out the sex at 20 week scan so we will know in 8 weeks!

Hi Ladies,

HAPPY EASTER!!!!!

This was a burning question I had also! I searched google that many times to try and find an answer but couldn't come up with anything concrete except that ICSI was suposed to more likely produce boys as they divide quicker and are therefore transferred more often due to being further progressed at time of transfer.

Well, at least I can contribute from personal experience now . We did ICSI to concieve DS1 on a fresh cycle (two eggs transferred but only one stuck) and had 5 frozen embryo's from that batch. We were very fortunate to achieve another BFP when trying for #2 from this batch of embryo's (our lucky last embryo - see signature... we lost 2 on thaw #2). My current BFP is a DD so I am living proof that you can get both a DS & DD from the same batch of ICSI eggs! I guess the above theory holds true for me... my last transferred egg which you would think would be my lowest graded egg at the time they were frozen was a DD.

Hope this helps in some way....Good Luck for whatever it is you are wishing for, oxox

PS: In saying that I still think it is almost a 50/50 thing cause many girls I know had DD on a fresh transfer !!

Interesting thread, Two ICSI miracles for us - from different stim cycles - First was DS, now DD is cooking!

My understanding with ICSI is that the most healthy sperm is selected for injection - not necessarily the fastest, but the morphology (shape/perfection) taken into account rather than just the motility (Movement/speed) which would make it a very random process from a gender outcome I reckon!!

Happy Easter everyone!

It is a rather interesting question

I had 2 boys from one cycle, one fresh one frozen, with ISCI.

Agree I was going to write the same thing. I too am of the understanding that the sperm chosen are the ones that "look" the most perfect/healthy and that the ratio of boy and girl sperm would in most cases be fairly even.

I consulted Google and found a few interesting articles that suggests that with ICSI the gender spread is pretty much 50/50 whereas with natural conception its approx 105 male to 100 females - Interestingly there was a common theme that mother nature does this because the infant mortality rate etc was higher with males etc so in laymens terms this 'evens things up'. One of the articles is here Fewer Boys Are Born After ICSI: Injecting Sperm Directly into the Egg Results in Fewer Male Births | Suite101.com

I found another article of interest too, but can't find it again

Andi - In a nutshell, if ICSI is used instead of normal IVF, there is really no statistics that significantly increase the chances of boys or girls, and whether its in the same stim cycle or not doesn't appear to make much difference as each fertilization is going to be independent of each other in reality, and with regards to the odds it is still only a matter of a few percent either way which is almost inconsequential I guess. I wonder if any of the IVF clinic's release stats on this though, would be very interesting wouldn't it!

This is quite interesting and something I had never thought about before.

So for my two cents, we have done five cycles of ICSI and it was lucky number five for us. I am currently pregnant with fraternal twin girls which does seem to agree with Naomi's article of fewer male births. You would think that it would still be fifty fifty but who knows.

Anywho, if you are doing or about to do another cycle, best of luck to you hon

Same as nai here... First Icsi miracle ds now baking a dd and they are from the same batch. So dd was frozen embie transfer xx

[TaRhLi.]

We got DD first and then twin boys all from the same batch and all FET's for us.

Thanks everyone - that was an interesting read! Glad I wasn't the only one wondering about this!

Either way I'd be happy with another girl if that's the outcome, however looking from all your responses I reckon a boy is in the race too! (although in our ICSI world it's not so much of a race for the little buggers iykwim! Haha)
