Finasteride

Optimal result: 0 – 5 pg/mL

Finasteride is a 5α-reductase inhibitor used to block the formation of the potent androgen DHT from its precursor, testosterone. It is used to treat benign prostatic hyperplasia as well as male pattern baldness in men and women, and excessive facial or body hair growth in women.

Serum testosterone levels increase as a result of the reduced conversion to DHT, but the increase is not usually outside the normal range

. Treatment with finasteride has been linked with sexual side effects.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
