This past May I was diagnosed with low testosterone and have been working with an endocrinologist over the past few months to understand the cause, but so far the cause is unknown. Since May I’ve had four rounds of blood tests and I’m averaging 59 ng/dL (normal range 350-1100 ) of Total Testosterone and 10.6 pg/mL (normal range 35-155) of Free Testosterone with my most recent results in November of 30 ng/dL and 4.4 pg/mL respectively. I’ve also had my LH (0.9 mIU/L average with the normal range of 1-10) and FSH (0.5 mIU/L with a normal range of 1-10 mIU/L) evaluated and I guess my results indicate that my pituitary gland has pretty much shut down. I’ve been told by two different endocrinologists that my body weight (5’8" & 128 lbs: BMI of 19.5) and training volume (about 12 hrs / week for peak training volume) are not the cause of my lack of pituitary function and low testosterone. However, through my research I found some antidotes and studies on endurance training negatively impacting testosterone and I’m wondering if triathlon training isn’t the culprit.
In light of this, I was wondering if anyone has seen endurance training negatively impact testosterone production as severely as my results show and if they’ve also had low LH and FSH? Furthermore, I haven’t been able to find much evidence on natural recovery from low testosterone without replacement therapy (found a lot of recommendations, but not much on case studies or proof of success). Has anyone successfully been able to restore testosterone production naturally? If so, how long did it take and what was your keys to success? Any information anyone can share is greatly appreciated because right now I’m being told my only option is testosterone replacement therapy, with cause of low T unknown, and I’m trying to avoid medication unless absolutely necessary. Thanks.
