And mine...
You say: Public Health England (PHE) works hard to reduce inequalities in health regardless of age, gender identity, religion, ethnicity or sexual orientation.
I think you may need to go and read the Equalities Act 2010 as you are misquoting the protected characteristics, leaving yourselves open to accusations of discrimination.
By all means refer to transmen by their preferred pronouns. By all means work out the IT issue you have with transpeople and computer designation of SEX!
But do remember that the EA 2010 is an extant law and you need to act according to its actual wording the wishful thinking of trans supporting organisations.
All pregnant people are of the same SEX... see that? Not gender identity but biologically based sex. No matter how an individual identifies, they retain their natal sex. You are the NHS, you know that!! No matter how politically correct you wish to be, you know about sexual dimorphism.
Keep your brave and stunning headline "Pregnant Men" but do have a good look at what you are doing to the EA 2010 and how that could very easily be detrimental to you; over 50% of the world population; funding for sex based services; research into sex based medical conditions, etc.
