• Your total
testosterone is normal/high at 890 ng/dL, but your free testosterone is very low (1.7 ng/dL), meaning only about 0.18% is available, far below the typical 1–2% range.
• This discrepancy often points to high levels of Sex Hormone-Binding Globulin (SHBG), which binds testosterone and makes it inactive.
• Your low
FSH (1.4 mIU/mL) raises concerns about potential pituitary or estrogen-related feedback issues, which might be linked to your long history of gynecomastia and current sexual dysfunction.
• Additional testing—such as measuring SHBG, estradiol,
LH,
prolactin, and
thyroid hormones—is needed for a full picture.
• Consultation with good endocrinologist and urologist is recommended to properly diagnose and manage the underlying hormonal imbalance.
