Testosterone (Total) Test

Why is morning testing recommended?

Testosterone follows a natural daily rhythm, peaking in the early morning and gradually declining through the day, so morning testing gives the most representative and clinically useful reading.

Does testosterone naturally decline with age in men?

Yes, testosterone levels gradually decline starting around the early 30s in most men, though a sharp or symptomatic drop should still be evaluated rather than assumed to be purely age-related.

What causes high testosterone in women?

Polycystic ovary syndrome (PCOS) is the most common cause, though certain adrenal gland conditions and, rarely, hormone-producing tumors can also raise testosterone levels in women.
