Possible to test for x or y sperm?
Hi - is it possible to test sperm, from a sample given, for percentage
of x or y chromosomes? Semen analysis check for sperm count and quality etc, but can a check for the number of X as opposed to Y chromosomes be done? We have 3 girls and want to know if we have any likelihood of having a boy next if we conceive again. |

We have 3 girls and want to know if we have any likelihood of having a boy next if we conceive again. It's possible to do "sperm spinning" which is a procedure some offices will do. It's not covered by insurance and it is not a guarantee. I have a friend who did it after 2 boys and she got a girl...of course there's no way of knowing what she would have had without the sperm spinning. I'm guessing the Xs are heavier, so it's easier to separate them out. I think it's less effective if you want a boy, but it's certainly worth asking your doctor about. You may have to go to a fertility doctor to perform the procedure, and you'll have to have an insemination. Good luck, Jen |

Hi my understanding is that Dr. Shettles theory has been recently
largely disproved...http://www.in-gender.com/cs/blogs/Ge...1/13/5342.aspx For more about sex selection, which methods work, don't work etc., and a very interesting website on the subject, check out in-gender.com. The woman who created the site has been doing sort of a grass roots research into sex selection and she has a great deal of information, along with forums where people post what method they tried and what the results were, etc....

Do you have reason to believe there is something wrong with your DH's Y chromosome? That's unlikely. Do you know about timing fertilization? It's very low tech and you can do it at home. |

I dont want any sperm spinning treatment or want to influence what
might be the outcome of conception artificially. I just want to know what the likelihood of conceiving one sex over the other is. Surely there must be a simple test (percentage of x to y sperm) out there that can be done? And surely this is the best way of determining what the likely outcome is as this is the only deciding factor on whether the baby will be a girl or boy? not at all, even if you put a mix of 50/50 g/b sperm into a vagina as they make the long journey to meet the egg lots don't make it, and for all sorts of reasons the barriers could cut out more of one sex than another, cervical mucous is pretty hostile stuff killing of massive numbers of sperm, it may be that the combination of you and your wife kill off more boy sperm than girl sperm. Then there are other stages in the process when the exact combination of you and your wife could make one sex have a much higher chance than the other, such as female sperm penetrating the egg easier, then once and embryo is made, male ones my be less likely to implant, there are just so many variables, that I suspect that determining the proportion in the sperm is going to tell you almost nothing. No one has really come up with a convincing explaination, but throughout history there is clear evidence that some families are heavy in females and others in males. My dads family for example has 1in4 to 1in5 rate of males being born historically, and then much lower life expectancy for those males. Cheers Anne |
