Testosterone and Thyroid levels interpretation help please
« on: June 14, 2025, 05:32:07 PM »

Hi everyone,
I'm 39 and under Newson's with cyclical cyclogest and cyclical Oestrogel.
Had a blood test done to see if Testosterone could help with low libido and brain fog.
Results came back the following Testosterone 0.949 nmol/l
                                               SHGB 26.9 nmol/l
                                               Oestradiol 206 pmol/l
                                               Progesterone 0.31 nmol/l

Also had Thyroid tested TSH 1.57 mlU/l
                                   FT4  12.6 pmol/l
                                   FT 3 5.08 pmol/l
                                   Anti Tg 39.1 IU/ml
                                   Anti TPO under 9.00 kU/l


Apart from SHGB which is low, everything is in the Randox range of normal. I guess my question is what levels have people had that have been prescribed testosterone?

Appreciate every input I can get. I will obviously pass this on to Newson's but googling has set my anxiety off especially re the TSH and FT4 being on the lower end of normal.

Thank you

Hello Pippi


I am not sure if this is relevant but when I was offered testosterone from Newson Health their only concern was that I had sufficient oestrogen. I was told that I needed a decent amount of oestrogen before taking testosterone or the benefits of taking extra T would be lost.

I hope this is of some help.

Take care.

Hi Kathleen,

thanks for getting back to me and this does certainly help. I am currently still a bit hesitant re the Oestrogel and only take it in luteal.
Can I ask how old you were when you started testosterone?

thank you

Hi pippi,

Did you get a free androgen index?

This is much easier to interpret.

Your estradiol is lower than I would be happy with, however gel peaks quickly then drops off so blood levels on gel can be hard to measure. However it indicates your own production is low because unless this was an early follicular phase sample, you would expect to have more than that naturally at 39.

Your testosterone is in "normal" range but some people including myself feel better when higher up in this range.

A lower SHBG can mean more biologically available testosterone in the blood, hence FAI is helpful.

I believe Newson are happy with a FAI up to 5. Mine is around 5, which I achieve with DHEA. I have taken this since age 41.

They are right about it being better (but not mandatory) to have healthy estrogen levels before adding T.

Otherwise your estrogen-hungry body simply aromatises the T to estradiol as fast as it can, so you are essentially just taking really expensive estrogen.

I am not an expert in thyroid but I would be very happy if those results were mine. A lowish T4 doesn't really matter if your T3 is good, it is clearly being converted and it is T3 which is biologically active.

Hi, thank you so much bombsh3ll. I've only just seen your reply. very much appreciate you taking the time to comment.
I forgot to say in my original post that this was taken on CD 3. My FAI is 3.53%.
Newson came back to me saying that I should wait adding testosterone so I'll see how things are when I have my follow up in September.
My SHGB is very low according to them and googling hasn't helped. :( I really need to sort out my weight I guess.
