my FSH is 1.5 mIU/mL on a flag reference range of 1.6-8.0 is this normal for a 20 year old male? every where i look on the web says that3.0 mIU/mL is ideal. should i set up an appointment with an endo? my LH was 4.5 on a flag reference range of 1.5-9.3 mIU/mL. my testosterone was 505 ng/dL. as you can see all my numbers are in the low normal range. could my blood test result indicate secondry hypogonadism. i recently cancalled an appointment with an endo, because i felt asthough i might be seeming like a hypochondriac.
