    What age is "normal" for a healthy man's sexual function to begin to decline?

    I appreciate the feedback. I have another question but am going to ask it in a different thread.

    What age is "normal" for a healthy man's sexual function to begin to decline?

    Interesting articles, thank you. So I take it the changes I described in my post are normal to happen sometime in one's 40s (for men in the industrialized world) and are not necessarily early "andropause" or necessarily an issue with my body's systems, but rather something most every man in the...

    What age is "normal" for a healthy man's sexual function to begin to decline?

    What age is "normal" for a healthy man's sexual function to begin to decline? I always thought it would be like age 55 or so. At age 43 here, I have the "I don't feel like I used to" feeling a lot of the time now. This has surprised me because I have had excellent sexual function my entire life...

    Detailed Labs of 42yr old healthy with some recent sexual symptoms

    Are there blood tests that measure levels of the 5α-reductase enzyme and the Aromatase enzyme directly? I have lower end Free T but have upper end DHT and am wondering if it is because my body is producing too much 5α-reductase enzyme?

    Detailed Labs of 42yr old healthy with some recent sexual symptoms

    What do you guys think about this? With a little bit of exercise and effort on my part, I can keep my total T levels around 600 plus a few points. So while my natural T isn't super high, it's not really low either. My free T is low and my SHBG is high. Interestingly, my DHT and Free Estradiol...

    Thank you - very helpful feedback! I used a Free T calculator (Free & Bioavailable Testosterone calculator) and entered some sample Total T, Albumin, and SHBG values to check what corresponding Free T levels would be: Example 1 Example 2 Am I right to think that the lower range Free T...

    Thanks again, very helpful. I agree, I would first like to try to figure out the root cause rather than forever bandaid the effects with Cialis, herbs, or even hormone adjusters. I do need to vitamin supplement better. And maybe ultimately I will need a direct hormone adjustment, but I would...

    Detailed Labs of 42yr old healthy with some recent sexual symptoms

    Thank you for the comments. I'll have to try that Natesto to see if it makes a difference to my symptoms. Nice that there is a low risk way to somewhat trial TRT with that. One thing I am curious about is whether my symptoms are "normal" for my age and whether their onset (seemed like most of...

    Detailed Labs of 42yr old healthy with some recent sexual symptoms

    I know what you mean, it is very frustrating laying awake at night staring at the ceiling. I had two sleep studies done, one at-home and one in-lab. Both confirmed I do not have sleep apnea. Unfortunately they didn't have guidance on what else might be the issue, though I suspect it is Low-T.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
