Propecia in a few guys causes an epigenetic change in gene expression. Typically we see very low LH/FSH, but that is not you. Many be changes in testes.
Your posted details also suggest changes from DHT deprivation.
When FSH is a lot higher that LH in young men, we suspect possible FSH secreting testicular cancer. Ask to get examined if any tenderness or something feels odd.
Need SHBG result and range.
Vitamin D? Vit-D25?, Vit-D2, Vit-D3?
Low E2 indicates low average FT, FT varies a lot and lab may have hit a peak.
TT is mid range, doc may not see that you need TRT
You crashed on stimulants and over training. Could be adrenal fatigue.
TSH should be nearer to 1.0
Were you not using iodized salt?
Outer eyebrows sparse?
Feeling cold easier?
Please check oral body temperatures as per the thyroid basics sticky to eval your overall thyroid function.
Labs: - fill in the gaps
TSH - post body temps and we can firm up need for following
fT4 - please not T3, T4
AM cortisol ?????????
Changes to testes and penis really do not make sense with your current LH/FSH, suggesting that something deeper is going on. Maybe low DHT shut down your junk. DHT is essential for development of male sex organs, not just T. If you get high normal TT and FT, then FT-->DHT may help things. TRT will shutdown LH/FSH and you would need hCG to maintain/restore testes as well.
Is your scrotum tight as well?
So the above covers major hormones and cortisol. What is missing is Vit-D25 hormone, made from Vit-D3. Take 5000iu Vit-D3, find tiny oil based caps.
