It seems to be a growing demographic:

A transgender couple have revealed they are expecting their first baby in a month’s time.
Scott Moore — thought to be only the second ‘pregnant man’ to go public — is due to give birth to a boy in February, with husband Thomas by his side.
The couple were both born girls and have undergone surgery to transform their sex.

The Obama administration trumpets its so-called commitment to diversity, yet it has yet to appoint a single pregnant male transsexual married to another male transsexual to any prominent position.
