Q: Which condition requires medication to prevent the conversion of testosterone to dihydrotestosterone to avoid cell proliferation?  

Answer: B

Benign prostatic hyperplasia (BPH) is a condition that causes the enlargement of the prostate gland, which is found in men. The prostate gland surrounds the urethra, which is the tube that carries urine from the bladder out of the body. The increased size of the prostate gland in BPH can result in a range of urinary symptoms, including difficulty starting urination, weak urine flow, and a need to urinate frequently or urgently.
One of the treatments for BPH involves medication that inhibits the conversion of testosterone to dihydrotestosterone (DHT). DHT is a hormone that plays a role in the growth and proliferation of prostate cells, and by inhibiting its production, the medication can slow down the growth of the prostate gland and reduce the associated urinary symptoms.
The medication used for this purpose is called a 5-alpha-reductase inhibitor. Examples of 5-alpha-reductase inhibitors that are commonly used to treat BPH include finasteride and dutasteride.
