finasteride 5α-reductase type 2 androgen receptor intracellular junctional proteins DHT androgen supplementation renal dysfunction renal transplantation Propecia dihydrotestosterone kidney disease

TLDR Finasteride may cause kidney damage.

The study investigated the effects of finasteride, a drug used to treat hair loss, on the kidneys of male rats. The researchers found that finasteride treatment led to a decrease in androgen receptor expression and changes in intracellular junctional proteins, which were associated with pathomorphological changes in the rats' kidneys. The study suggests that patients with renal dysfunction or following renal transplantation with androgen supplementation or with pharmacologically induced DHT deficiency should be under special control and covered by extended diagnostics due to the potential adverse effect of DHT deficiency on the progression of kidney disease.
