Serum dihydrotestosterone in patients with benign prostatic hypertrophy

Area of Science:

• Endocrinology
• Urology
• Gerontology

Background:

• Benign prostatic hypertrophy (BPH) is a common condition in aging men.
• Hormonal changes, particularly androgens like testosterone and dihydrotestosterone (DHT), are implicated in BPH development.
• Understanding the role of these hormones is crucial for BPH management.

Purpose of the Study:

• To compare serum dihydrotestosterone (DHT) and testosterone levels in normal aging men and those with benign prostatic hypertrophy (BPH).
• To evaluate the clinical utility of serum DHT measurements in diagnosing BPH.
• To explore the potential prostatic contribution to circulating DHT levels and its relevance to BPH etiology.

Main Methods:

• Radioimmunoassay was used to measure serum DHT and testosterone levels.
• Study included 24 normal men and 25 men with BPH, all aged 60-80 years.

Main Results:

• Patients with BPH showed a significant increase in serum DHT levels compared to normal men.
• No significant difference in serum testosterone levels was observed between the two groups.
• High variability in individual DHT values suggested limited diagnostic value for BPH.

Conclusions:

• Elevated serum DHT in BPH patients may indicate a prostatic contribution to circulating levels.
• The findings suggest a potential role for DHT in the etiology of benign prostatic hypertrophy.
• Serum DHT measurement is not a practical clinical tool for diagnosing BPH.
