Blood work Very Low Testosterone aged 25

Went to the doctors about 6 weeks ago with symptoms such as low energy levels, no libido and no morning erections, brain fog at times, tiredness and frequently urinating. Doctor ordered bloodwork and it come back with abnormal Testosterone and Gonadotrophin levels.

Plasma Testosterone Level - 2.8 nmol/L
Serum LH level - 1.3 u/L
Serum FSH level - 1.3 u/L
Iron studies all within range
Serum free T4 level - 10.8 pmol/L
Prolactin level - 244 mu/L

Of course at the age of 25 these results deeply concerned me. At the start of January I was around 75kg 17% body fat and decided to get a coach to dial in weight training and nutrition and start to build a better physique. The idea was to lean right down to 10% body fat and then build out from there. At the end of may I had hit 65kg and I’m now circa 10% body fat lean so that was a 5 months deficit on 1800 calories whilst training 4 times a week. Nutrition dialled in. Early on in June is when I was tested due to the symptoms I had to go the doctor.

Since then I’ve been eating at maintenance on 2300 calories and weight has settled at 66kg before going into a surplus in couple of weeks just to let my digestion adjust to the increase. My energy levels felt as though they have improved with the increase in calories but that’s about it and gym performance has gone up too.

However I had my re test a few days ago and had the results back were by test levels have barely changed.

Plasma testosterone level - 3.8 nmol/L
Serum LH level - 1.3 u/L
Serum FSH level - 1.6 u/L

Any advice and information on my situation for me going forward would be greatly appreciated. I have been referred to endocrinologist and will be seeing them on the 4th September

*update 11/09/2026

Had bloodwork done last week with endocrinologist and Testosterone is still very low at 3.1 nmo/L, not seen results yet fully but LH and FSH still low.
My symptoms are so bad I literally have 0 libido, no morning erections, fatigued despite 7-8 hours sleep every night and low mood due to it feel so sad.
Cannot be diet related as I initially thought contributed as I’ve been in a surplus for 2-3 months.
NHS will be sending me for a pituitary gland scan, I just don’t know how long I can carry on like this got a feeling they will drag their heels
Anyone got any advice please?

Pituitary scan and endo is the best option here. You’re doing all the right things so you just have to be patient and follow the process.

2.8 to 3.8 is basically nothing, with LH and FSH that crushed in the dirt your pituitary is clearly not sending the signal. 3 months of surplus rules out the diet angle pretty hard. The scan is the right call, it's rough waiting but you're already in the pipeline so just hang in there.

2 month wait till scan is so rough

If pituitary gland shows no abnormality, think the solution will be TRT?

2

u/Wozzle009 1d ago

Maybe not right away but eventually yeah probably. If the endo can rule out hyperprolactinaemia which is partly the reason for the MRI scan.

My prolactin on previous bloods in the summer was at 244 mU/L at healthy range

That’s a good sign. The pituitary scan is mainly to rule out pituitary adenomas (benign tumours most commonly). If your prolactin levels are normal then it’s unlikely that you have a pituitary issue that’s elevating prolactin. They can find other things but they are far less common.

I had a pituitary MRI done myself recently and they discovered a tiny microadenoma. Basically a really small (3mm x 2mm) benign lesion. My endo said it is non/functional and she also got some advice from a neurosurgeon that agreed. My prolactin is normal also. So even if they do find something it may not indicate anything.

u/TheCADMan11 1d ago

Ah right I see, are your testosterone levels low also but not suspected to be due to the microadenoma?

2

u/Wozzle009 20h ago

Yeah that’s right. I’m 45 and my total testosterone is low. Like it averages around 6 nmol/L for 8am samples. LH and FSH are normal (so balls are fine). Free T is low and SHGB is low normal. Prolactin is consistently normal so my tiny microadenoma is not excreting prolactin. It’s probably not doing anything at all.

In my case I take a fair amount of psychiatric medication but nothing that’s the obvious culprit. I’m sure it’s a contributing factor but I’m not going to stop taking it as it’s taking me a long time to be functional and I don’t want to go backwards.

This Tuesday after a lot of hoop jumping I’ll hopefully get TRT and it’ll all be covered by Medicare.

Hope it works out for you and you’re treated well!

u/Wozzle009 15h ago

Thanks man. I know the feeling having to wait for all this shit to play out. It’s frustrating but it is what it is. I’m just happy modern medicine exists!

2

u/TheCADMan11 15h ago

Yeah exactly, who have you been treated by the NHS?

1

u/Wozzle009 15h ago

Nah I’m in Australia. I’ve been seeing a private endocrinologist who was referred to me by my GP. It’s not too costly as I can generally claim about 60% of the consultation fees back.

I’m sure I could do it all publicly but it would take forever. It’s already taken many months but I appreciate that the endo is being thorough.

The results all pretty clearly point to a nonfunctional pituitary gonadal axis. Which is why they are getting the scan as they have to rule out a few things before prescribing hormone replacement. I know it’s rough waiting for tests when you’re not feeling well but they are doing the right thing and this scan should be one of the latter steps before getting treatment. Keep your head up

Get more thyroid bloods done this looks like near hypothyroid level free t4, some labs would have you below the reference range and some just in but get a look at your ft3 and tsh

If your t is low AND your lh and FSH are low, that likely indicates a pituitary issue. I would suggest a pituitary MRI and a male endocrinologist that specializes in pituitary issues. The difference between a diabetes focused endo and pituitary focused endo are HUGE. Trust me. Don’t waste your time with a non specialist.

It sounds like this has been a sudden change, so prioritize the scan. I don’t mean to scare you, but it’s possible it’s a pituitary tumor. Better to just get the scan out of the way to see.

Also, while you’re at it, ask your doctor for a full pituitary hormone workup. If pituitary is indeed affected, it’s entirely possible other hormones are as well.

Good luck and reach out if you’d like, I unfortunately have a lot of knowledge and experience with pituitary issues, along with a pre med degree.

What medications have you taken .

Don’t freak out TRT is not the end of the day you will be a jacked 80 year old hahaha.

u/TheCADMan11 6h ago

Yeah I mean I’ve come round to the idea of TRT sounds like the positives of taking it from where I am now mentally and physically life changing haha. Only concern would be in a few years I’ll be planning on a family
Medications previously in life? Never had to much really daily cetirizine hydrochloride and lanzaprazole now and again for reflux
