Which medication can lower testosterone levels?

Ibuprofen
Cimetidine
Levothyroxine
Aspirin

The correct answer is: Cimetidine

Cimetidine can lower testosterone levels by inhibiting the enzyme responsible for converting testosterone to dihydrotestosterone. This leads to an increase in circulating testosterone levels and a decrease in dihydrotestosterone levels. Ibuprofen, levothyroxine, and aspirin do not have an impact on testosterone levels.
