DH is (not without reason) becoming fairly certain that low testosterone may be a factor in some ongoing physical and mental health issues. He does all of the right things re. exercise, diet, alcohol, sleep (at least 80% of the time), he's 42 for what it's worth.
Has anyone had any experience of men in their life having undertaken testosterone supplementation (cream or injection?) There was an article in today's Guardian which has made him more determined to look at going down this route and I'd be more comfortable to hear directly of positive or negative experiences.
