Is it true IVF favors male babies?

My good friend has a son due to ivf and just found out she is pregnant with twins from ivf, she was told by someone that it is much more likely to have boys from ivf, is this true????  Anyone want to weigh in?  experience?

I have had two IVFs and have not heard of this.  hmmm...  I have heard that the timing of intercourse can affect the sex of the baby, but with IVF all the sperm, X or Y, are introduced at the same time.

Oh no, I hope this isn't true!!! Any baby is WONDERFUL but we did sperm spinning for a girl (My husband has produced 5 boys)! I can't wait to read the answers to this question.

A friend of mine had IVF & had a girl, but maybe she was the exception.

lynda, what is sperm spinning?  Just curious!

[lynda544]

Sperm spinning is where the semen is placed in a centrifuge and spun until the x-chromosome (girl) sperm is separated from the y chromosome (boy) sperm. After spinning, the x-chromosome sperm will be found in greater concentrations at the bottom of the sample and the y-chromosome sperm will be found in greater numbers at the top. The desired boy/girl sperm are extracted from the sample and used during IVF. It is reported to be 70% accurate.

well one of my clients had a succesful IVF & has a little girl who is 5 now. As far as I am aware the female can only put in an X chromosome & the male is the one who determines sex by either putting x of y. So not sure how IVF would effect that.
