Hey, I know this was last touched on 2 years ago, but I have some potentially valuable advice. My story is LOW T and Infertility that reared it's head at 30 y/o. I've been through way too many doctors. I also had a bad reaction to TRT (anxiety/high blood pressure) so had to stop.
My goal was/is to find the reason why all this is happening, not bandaid it. In the process of trying to bandaid temporarily (supplement T), I had a bad reaction, and that increased my drive to get to the bottom of my problems.
I am now doing genetic testing from 23andme.com and testing via Genova which is called NutraEval. Also, look at Spectracell.com for micronutrient testing. Genova NutrEval tests heavy metals, amino acids, fatty acids and more. Genetic and nutritional testing is the future of medicine. What I see in your instance is potentially similar to mine:
You have low B Vitamins in your first test, and you have high homocysteine. 11 is still high. From what I hear, ideal is around 7 for homocysteine. What that tells me could be that you have methylation pathway issues as I do (and many people do), and you need to get 23andme.com done (gene snps) and get with an integrative doctor to help address your methylation pathway, if your genetic results deem that an issue.
My methylation pathways are all messed up due to my genetic faults. Most people are much different, and have less severity. Methylation has to do with assimilating b vitamins and passing those on to be used in the rest of the methylation cycle (biochemical reactions) which produces energy, antioxidants, and more for cell health and function. Even if your b vitamin levels are up, you may not have the ability to absorb them, hence they are free floating in the blood. People with methylation issues need to be supplementing with bio-available forms of b vitamins, like 5-mthf or methylfolate (Folate) and methylcobalamin (B12). But, you need to do the genetic test and work with an integrative doctor in order to manage this healing process. You can't just jump right in and supplement, trust me.
This is my best guess for many with Low T, all dependent on bloodwork and other markers, of course. For me, I am in the middle of it right now. I've always been a very healthy guy, and there is no reason for what is happening, except for our toxic world, and many of us don't have the genetics to battle it as best we can. Best of luck, and I hope you find some sort of path to recovery.
