Can spironolactone lower your androgens to low? Dhyi and andro labs below normal, testosterone normal. Is this desired or can it cause problems?

No. Spironolactone blocks androgen effect by blocking Androgen receptors but it does not lower Androgen level. It is commonly used to relief symptoms of Androgen excess like hirsutism ( excessive body & facial hair). Be careful it is teratogenic ( may cause birth defects) and should be used with a reliable method of contraception.
