I’ve only attended one presentation on it and I’ve never read about it but apparently there is a significantly increased chance of having a male pregnancy after IVF assuming you have a blastocyst transfer because apparently and I don’t know what with this any scientific evidence to back it up but apparently according to this presentation because the male embryos start to expand a blastocyst that bit quicker and that’s what we look for when we’re selecting the embryos, we’re looking for expanded blastocysts, we’re subconsciously selecting male embryos and supposedly there was a significantly improved chance of having a male child after having a blastocyst transfer but we’re talking a very small percentage but still considered a significant result and up outside of that one study, I don’t know of any others in terms of the initial embryo development, the fertilization stage, the first cleavage, the Day 2 and the Day 3 cleavage as far as I would be aware there would be absolutely no difference. iIt’s just once we get to the blastocyst, the male embryos may expand quicker
Answer from:
I don’t know about all that but I think the chromosome of the male is very small and very tiny and so errors can occur with these chromosomes and in the case of the female we have 2XX. So I think with their recommendations, more…
Answer from:
In studies we see that the blastocyst expands faster than the female blastocyst, so that’s the most common characteristic I know of; sometimes the rate of male reproduction is higher because the blastocyst expands faster and when you do the transfer you select the more expanded blastocyst, obviously.
