Sorry you’re feeling so overwhelmed.
I am in very similar situation as you, but 8 months down the line.
I am not an endocrinologist but am an experienced HCP, and have spent the last 8 months reading numerous journal articles.
I have had a decade of vague worsening symptoms, increased fatigue, poor sleep, reduced exercise tolerance, weight gain, vaginal dryness, reduced libido.
Was originally advised to sort out my work life balance, I was working a rotating days and night shift pattern, so 7 years ago I dropped to part time days only, then became pregnant and had DD nearly 6 years ago.
More recently, I’m now 42, I have been dismissed by GP when complaining of no libido, told I have “a young child and need to carve out more time for sex” and that it wasn’t my hormones as I am “too young and periods too regular”. Eventually with DD sleeping consistently in her own bed through the night, and my libido (and all symptoms) getting worse and worse, and not being able to face discussing my sex life with a stranger again, I paid for a private blood test in April this year.
oestrogen 54pmol/l
FSH 9.6iu/l
Testosterone 0.4nmol/l
TSH 0.04mU/l
T4 16.7pmol/l
I since had a repeat thyroid function test with normal results. Normal thyroid antibodies, normal prolactin levels and a normal MRI of my pituitary.
As a result I’m still, like you, none the wiser.
I am currently on 150mcg Everol patches (my oestrogen levels have been stubbornly low), Utrogestan 100mg vaginally day 15-28, and 5mg testosterone daily.
My endocrinologist now wants to investigate for Cyclical Cushing syndrome, but for the Cortisol stimulation test I have to stop taking HRT 6 weeks before, and may require some repeat testing. The thought of being off HRT and back in the dark place I was last April is terrifying.
What I have realised is most doctors understand very little about complex pituitary problems, and even endocrinologists can be baffled, so don’t stop pushing for an answer.
The treatment for hypogonadotrophic hypogonadism is standard HRT, the only time they give Gonadotropins is if you want to try to conceive, so don’t worry about going down the HRT route, you need these hormones.
If your cortisol is on the high side, then I would have thought a stimulation test would be indicated and this is something to do NOW not make you start and then stop your HRT in order to do it later.
Did you have contrast injected for your MRI, this is important for seeing all the potential issues of the pituitary? Having said that 9% of people with hypopituitarism have nothing abnormal visible on MRI (I’ll link some journal articles later, as I’m in the car at the moment).
What were the results of your thyroid function test?
