Stored ICSI embryo's and gender

[MummyNaomi]

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
