Soldiers sperm???

I served in the UK Military between 1981 and 1990. On leaving I married and within a year we had twin daughters.

We now have 4 very healthy daughters and realised last week that most of the guys who I served with also have daughters.

Any serving or ex military people out there notice a trend, either sons or daughters produced by guys they served with?

Shouts "HELP" to the nearest Moderator.........Wrong topic board to post this! Sorry

I am not in contact with any of the guys that I served with, but my wife gave birth to a boy.

He has some health problems and I am disabled.
