Blossom, you're right in regard to it being very bad luck that you both have a sex chromosome related abnormality affecting fertility.

I don't think you'll find anyone on this forum who has much knowledge of Turner Syndrome as it isn't that common. I think your best bet is to continue to consult with your fertility specialist, perhaps also in liaison with a geneticist.

For background, and you may already know all of this, Turner Syndrome involves the deletion or partial deletion of one of your two sex chromosomes, which form part of the 23 pairs of chromosomes you possess. Klinefelter's ironically is the addition of an extra sex chromosome, which also confuses the body's fertility abilities.

Hope that helps, but as it's a very specialised field of medicine, there may not be a great deal of assistance available to you on forums such as these which do not comprise a specific genetics component. All the very best with it.
