Male Hormone Panel
A comprehensive assessment of male hormone levels including testosterone, estrogen, and related markers.
Purpose
The male hormone panel evaluates testosterone and related hormones that affect energy, mood, libido, muscle mass, and overall vitality. It helps diagnose hypogonadism (low testosterone), guides hormone therapy decisions, and monitors treatment effectiveness.
When to Order
Recommended for symptoms of low testosterone (fatigue, low libido, erectile dysfunction, mood changes, difficulty building muscle), infertility evaluation, or monitoring testosterone replacement therapy (TRT).
Preparation Instructions
Test in the morning (7-10 AM) when testosterone peaks. Fasting is typically required. If on TRT, test at consistent timing relative to your injection schedule (often at trough, before next injection).
Included Markers
Testosterone
nmol/L
Testosterone is the primary androgen (male sex hormone), produced mostly in the testes in men and in much smaller amounts by the ovaries and adrenal glands in women. Australian pathology labs report testosterone in nmol/L. Most circulating testosterone is bound to SHBG and albumin; only the small "free" fraction is biologically active. Levels follow a strong circadian pattern, peaking in the early morning, which is why diagnostic samples should be taken before 10 am.
Estradiol (Oestradiol, E2)
pmol/L
Oestradiol (E2) is the most potent of the three forms of oestrogen. In women it is produced primarily by the ovaries and varies dramatically across the menstrual cycle. In men it is produced by aromatisation of testosterone in fat, brain, bone and other tissues. Australian pathology labs report E2 in pmol/L; older US-style ng/dL or pg/mL conversions are sometimes seen on imported reports.
SHBG (Sex Hormone Binding Globulin)
nmol/L
SHBG (Sex Hormone Binding Globulin) is a glycoprotein produced by the liver that binds tightly to testosterone, dihydrotestosterone (DHT) and oestradiol. The portion of testosterone bound to SHBG is biologically inactive, so SHBG levels directly determine how much "free" (bioavailable) testosterone reaches tissues. Insulin and androgens lower SHBG; oestrogen, thyroid hormone and ageing raise it.
LH (Luteinising Hormone)
IU/L
A pituitary hormone that triggers ovulation and stimulates testosterone production.
FSH (Follicle Stimulating Hormone)
IU/L
A pituitary hormone that stimulates egg and sperm production.
Prolactin
mIU/L
A hormone best known for stimulating milk production.
