Infertility is not hereditary. Obviously if someone was infertile, there would be no offspring to pass on their defunct genes to! However a low-sperm count could be genetic.
There is also some medications that women have innocently taken in past that have caused their offspring to have difficulties - such has an anti-morning sickness drug from the 60's caused many girls to be born with an incomplete cervix.
There is no medical reason I can think of that would cause both male and female offspring to be infertile. It could be just a coincidence his siblings are having difficulties conceiving. And presumably your b'f is quite a different age from his siblings and from a different relationship, this means that their physical environment was different growing up. This would rule out an environmental problem (ie exposure to radiation).
I would not worry too much about it, but if you are trying to conceive and are having difficulties, it would be a valid point to ponder.
First off, the cue words are "Boyfriend's brother" Get it? You shouldn't be concerned about anything BUT your boyfriend. Including his brother.
First show your brother all nice things your boyfriend is and if he still doesn't like him tell you brother to talk to your boyfriend so your brother can get to know him. And he should like you boyfriend after he gets to know him
Yes
Obviously not...Unless your brother is going to be a d-bag to your boyfriend :)
In the movie The Bourne Identity, Marie's step-brother, Eamon and his children, live at the farmhouse where they seek refuge.

No, Bethany's brother doesn't have a girlfriend. He has a boyfriend.

Your children are the first cousins of your brother's children, and the first cousins once removed of your brother's grandchildren.
Your half brother's children and your children are half cousins. However, in casual conversation, you can also refer to them as cousins, just as you can refer to your half brother as your brother.
