What a high Total Testosterone can mean

  • In women: PCOS — most common; usually with elevated free androgen index, irregular periods, acne, hirsutism.
  • Congenital adrenal hyperplasia, androgen-secreting tumour — rarer.
  • Anabolic steroid use, testosterone replacement overdose — exogenous source.
  • In men: rarely a concern in routine practice; very high points to exogenous use or testicular tumour.

When to discuss with a doctor

In a man with persistent symptoms (low libido, fatigue, erectile dysfunction) and morning total testosterone <300 ng/dL on two occasions, an endocrinology / urology consultation is appropriate to decide on replacement vs investigating the cause. In a woman with elevated testosterone plus irregular cycles or hirsutism, a PCOS work-up is the usual next step. Mediora.AI surfaces the threshold; replacement therapy belongs with a physician.
