If you have more boys = DH only has Y sperm?

[Loveychoc]

.......This is what my mother is adamant to say these days! Just because dh and his family has boys obly , that is including his father, uncles and male (only) cousins. And I have a Boy too. (Geezz mother please show sympathy to your daughter!  )
And she said what if you went on HT and doctor found no x sperms at all on DH ..?
I dont think this is right.

Atomic sagebrush, please assure me that i can still have a chance to have a DD despite male lines run heavily on DH's side...  And assure me that dh wasnt born as YY (not having x ) instead of XY !

Hi Loveychoc,
No this is not true!! my dh has only males, cousins etc, we've had one failed ivf and we had 2 girls to transfer, many ladies on the high tech boards have many males in their family and their dh's still produce female sperm :-) don't lose hope!!! all men make 50/50 of male and female sperm x

No, it is not true and you can read about it here.

I have seen people shell out thousands of dollars "to have their husbands' sperm tested" and it is 50-50 every time. You will NOT go to HT and find he has no X sperm, that's completely untrue.

I've always wondered! I knew it wasn't possible that they only have Y sperm, but is there a reason why some families only have one gender? My SIL knew the second she married her husband she was giving up and liklihood of having daughters - his family, fathers family, uncles families, grandparents families.. there is not a single girl in probably 50 people. She had 2 boys. Her husbands brother also had a boy. How does this happen if the theory isn't true? I so assume dh can only make boys but we are the only people in either of our familes that only have boys.. every else also has girls so hopefully that means it could happen for us!

Other things also tend to run in families like lifestyle, diet, other health issues. There may be genetic factors such as, predisposition to PCOS or height that may play a part in swaying but it is NOT that men make more or less X or Y and it is NOT that your family is predestinied or "doomed" to make all of one gender. It is all about the signals you get from the environment about what gender has the best shot of survival - in your BIL's family for whatever reason, that "boy" signal has just come through loud and clear.

Gender is NOT genetic that way because whoever had those genes, the first time a war came thorugh and all the males got wiped out, which has happened a zillion times throughout history, those genes would have been completely wiped out and would never have survived to be handed down to us. It makes the most "sense" for our genes to favor having a baby with the best odds of survival male or female, instead of being "tied" to only one gender.
