Yes, that too, but the hormones have such a huge direct influence that everything else is secondary. It's such a delicate balance it's a wonder it ever works! :-)

There's a lot more to it than just BP and testosterone levels, as I'm discovering, and the average family doctor is not up to speed on the possible causes. ALL the hormones are involved, but in addition to the Big T, Estradiol (an estrogen) and prolatin need to be looked at closely: they can be "normal" and still be far from ideal. It is a balancing act that is harder to maintain as you get older.

I think you meant prolactin which is sometimes the cause of ED.

Yes, and did you know low vitamin D can actually cause low T? It can also cause inability to lose weight, maintain erection, and a variety of other ugly issues.

Indeed I did: prolactin. The flying fingers betray me far too often.
Your average general practitioner/family doctor won't even test for prolactin, and if he does, the upper end of what is called the "normal range" by most labs will be far too high for good sexual response/health. I had to be very convincing to my doctor to get him to research this some, where he found that even the mid-point of what his lab calls "normal" is undesirably high. Where normal for males is called 2 - 18 ng/mL, a desired level is around 2 -3
One very thorough study found that a significant number (over a third) of men who did not respond at all to sildenafil (Viagra), responded very well indeed after lowering their prolactin levels. Another study found that bringing prolactin down to the 2 - 2.5 range also reduced the refractory period between orgasms.

I live in North Texas: hardly anyone around here has a Vitamin D deficiency! :-))

My ex-g/f told me that when she was about 19, she was in love with a dude who was 4 years older than she. He smoked a lot of 420. When he didn't, he was able to cum a lot. When he was doing it, she had to work to get him off. She was so thoroughly in love with him that she did anything for him any time he wanted it, including anal sex. When her youthful exuberance faded, she saw him for who he really was & fell outta love with him faster than she fell in love with him.

I see the OP hasn't been around in a while, but on re-reading her first post, I see "gym supplements " which should have been a huge red flag! Who knows what's really in those, and there's a good chance they can completely screw up your endocrine system. But hey - they're a great substitute for actually doing the hard work.

I read gym supplements as steroids (which really do help you bulk up but are often illegal and have bad side effects.)
