Q. I am 53 and have the general symptoms of benign prostate enlargement. A year ago, my PSA was less than 4. I have been taking an over-the-counter herbal prostate pill twice a day for about two years, with no side effects. I’d like to know if it’s safe to also take a testosterone-precursor type of herbal supplement. I see several products advertised for increasing libido, but I have not seen any discussion as to the effect on the prostate. I am hesitant to consider such a pill at my age, due to my concern with prostate enlargement.
A. You are not alone in this concern. As men age, the prostate gland continues to grow due to natural hormonal changes. Most experts agree that increasing testosterone levels—especially in the prostate—can stimulate further gland enlargement and worsen urinary symptoms associated with benign prostatic hypertrophy (BPH). This occurs because testosterone is converted within the gland to dihydrotestosterone (DHT), a potent form believed to drive prostate growth.
Moreover, prostate cancer cells tend to thrive in the presence of testosterone. That’s why men on testosterone therapy must be closely monitored. Taking over-the-counter “testosterone booster” supplements without medical oversight could unintentionally accelerate both benign and malignant prostate tissue growth.

While herbal libido supplements may enhance sexual drive, many of them are poorly regulated. Some contain hidden or mislabeled ingredients that can interfere with prostate function or medications. Discuss any new supplement with your physician or urologist before use, particularly if you are already managing BPH or elevated PSA levels. Complementary strategies such as healthy lifestyle changes for middle-aged men—like exercise, weight management, and reduced alcohol intake—can also improve both libido and prostate health.
For further evidence-based information, you can refer to the Mayo Clinic’s overview on benign prostatic hyperplasia (BPH), which explains the role hormones play in prostate growth and the importance of safe supplementation.
In summary, testosterone-precursor supplements may not be safe for men with prostate enlargement. It’s best to consult a healthcare professional before combining any sex-enhancing herbal formula with prostate-supporting pills.
