A 46 year old patient has presented with difficulties

Customer Question

A 46 year old patient has presented with difficulties getting an erection , no significant risk factors , blood pressure and weight is OK, he is an ex smoker of 5 years but in his bloods he had a testosterone reading of 7.5 ( the range being 10-30) and
a LH of 1.4( range being 2-12), his TSH, prolactin and morning cortisol are normal. My main concern was the low LH, albeit it is only mildly low, but I would have thought with a mildly low testosterone LH would have gone up if anything unless there was pituitary
failure. Does this need further follow up? or could this be attributed to ageing that some men could have a drop off in LH and testosterone. He denies any steroid or testosterone use

Normal LH levels for men over 18 years of age is around 1.8 to 8.6 IU/L.
his LH levels are low for his testosterone level.
he could be having some failure of his pituitary gland making LH causing his low testosterone.
he should consult with an endocrinologist about this
there are medications like clomid which could help his testicles make more testosterone
let me know if you have questions.
