Check the small print of your policy to make sure you are covered for maternity care. I have executive level cover from AXA and exclude anything to do with maternity care, or for that matter the menopause, on the basis that neither are medical conditions. It's a policy carefully designed to avoid paying for most of the medical support women will seek over the course of their lifetime. They won't even pay for osteoporosis diagnostic tests or treatment until you break bones! I don't see any such exclusions particular to men's health.
If indeed your policy cover does include maternity care, I'd be really interested to know who provides it. I work in an industry which employs far more women that men, so I think AXA was a really poor choice of policy provider for us and I'd been keen to lobby HR to change.
Good luck in finding the right care!
