My new Endo and I decided to stop my TRT (Test cyp) after being on it for only ~3 months in order to figure out causes for low T. Here are the labs 6 weeks post last injection.
FSH 3.4* (1.5 - 12.4 mIU/mL)
Luteinizing Hormone 6.5* (1.7 - 8.6 mIU/mL)
Testosterone, Free 37.4* (35.0 - 155.0 pg/mL)
Testosterone, Total, LC/MS/MS 260* (250 - 1100 ng/dL SL)
The TT levels are back to what my TT were before TRT started. Also, weight and libido have returned to pre-TRT levels.
Plan: Since new diagnosis of mild obstructive sleep apnea, I will be starting CPAP next week and will retest Testosterone in 6-8 weeks before considering TRT again.
Questions:
1) What does having FSH and LH within normal range mean for possible causes of low testosterone?
2) How do I analyze Free T levels in relation to Total T?
