Hi TJ, thanks for reaching out! Will do my best to try and answer your questions.
Unfortunately you may not be entitled to treatment on the NHS as you already have a child but you can definitely access tests through your GP.
If you have a look in some of the posts, you might find some helpful info around supplements and vitamins that I have highlighted.
It can sometimes be a bit tricky for men to deal with fertility. They sometimes feel as if its just a female issue and that having fertility problems can make them appear as less of a man. It might be good to see if he can talk to a counsellor or someone who can support him. There is a fantastic podcast that has been set up by two men – where they discuss all about male fertility but from a males perspective that he might find helpful? Its called the male fertility podcast.
Unfortunately it does sometimes take guys a bit longer to digest things but maybe asking if he wants to talk about it or providing him with resources such as the podcast might help.
Hope that helps,
