35 year old male diagnose 6 months ago with secondary hypogonadism and hypothyroidism. My initial labs were:
Total Test: 186 (240-950)
Free Test: 7.0 (9-30)
LH: 2.3 (1.5-9.3)
FSH: 1.7 (1.6-8.0)
E2: 18 (<39)
SHBG: 15 (10-50)
Free T4: 1.35 (0.71-1.85)
Total T3: 115.6 (84.6-201.8)
TSH: 4.35 (0.50-4.65)
Endo decided to put me on clomid for 3 weeks to see if my pituitary would respond.
Total Test: 329 (240-950)
Free Test: 11.0 (9-30)
LH: 5.8 (1.5-9.3)
FSH: 2.9 (1.6-8.0)
E2: 22 (<39)
SHBG: 18 (10-50)
I was diagnosed with secondary hypogonadism probably as a consequence of obesity (6’2" @ 300lbs). I was given a few options for treatment including:
- Attempt weight reduction and reassess
- Continue with clomid and attempt weight reduction and reassess
- Start TRT and attempt weight reduction.
I didn’t like the way I felt on clomid and didn’t want that long term and for some reason felt uneasy starting TRT for secondary hypogonadism immediately so I chose option 1. Endo warned my that my current endocrine state was not conducive to weight loss and it would be an uphill battle. He started my on 100mcg Synthroid.
Fast forward 6 months later and I have been low carb dieting and exercising and lost 40 lbs. My most current labs are:
Total Test: 500 (240-950)
Free Test: 14 (9-30)
LH: 5.1 (1.5-9.3)
FSH: 5.5 (1.6-8.0)
E2: 22 (<39)
SHBG: 19 (10-50)
Free T4: 1.30 (0.71-1.85)
Total T3: 93 (84.6-201.8)
TSH: 1.87 (0.50-4.65)
Subjectively I feel good but not great. Making some better gains at the gym than in the past. Brain fogginess is lifting a bit but I’m still moody. I think I’ve made good progress with my weight reduction and pretty good increases in my T level but subjectively I’m not there yet. Furthermore, I’m rather discouraged that even with a relatively low E2 and normal SHBG a total T of 500 seems to be the maximum potential of my HPT axis. If this is the best I can do naturally I’m not satisfied.
I’ve been reading quite a bit in the past 6 months and there are a fair number of articles out there that point towards hyperglycemia/hyperinsulinemia secondary to excessive visceral fat as a primary cause of obesity-induced hypogonadism. Perhaps as important as high E2 as a potential cause. It’s interesting to note that my E2 has never been measured as elevated although I suspect early on in my obesity it was elevated before my test levels started bottoming out. Furthermore, it seems to me even if you’re secondary hypo and obese and you want to try recovery in the form of greatly reducing visceral fat stores through diet/exercise it is difficult just with the mere presence of the existing visceral fat stores and the resulting cascade of excess free fatty acids in the portal system leading to fatty liver, inflammation, insulin resistance, more hyperinsulinemia and a propensity toward fat storage in the form of visceral fat. Although I can not find a report in the literature linking c-peptide (as a measure of insulin resistance) directly to obesity-induced hypogonadism it does seem there maybe a link between insulin sensitivity and hypogonadism.
This lead me to the conclusion that I was thinking about my disease all wrong. My goal shouldn’t be to reduce weight and hope T levels respond. After all, my metabolism is setup against me achieving this goal on every level. Instead, I should be using TRT as adjunct to diet/exercise to biochemically set my body up to allow visceral fat loss. When I looked in the literature I found evidence to support this approach. Most notably is the recommendation that TRT should be used for weight loss in obesity as a primary treatment modality.
I did also consider HCG monotherapy and I think it was an option in my case assuming my Leydig cell reserve was sufficient. However there seems to be a growing consensus that test replacement is at least subjectively better at relieving low T symptoms that HCG monotherapy.
So I’ve decided to start test IM injections, wait for blood levels to stabilize and if I feel better and the numbers look good do small doses of HCG 2 and 1 day before weekly injections to keep my testicles from completely shutting down. I also hope maybe one day when I’m significantly thinner with better insulin control try a restart.
Comments are welcome. This is not saying much but my endo went along with this plan without much hesitation.
