    Hormonal factors influence benign prostatic hyperplasia (BPH) in dogs. Androstanediol, not testosterone, with estradiol, replicated canine BPH features, offering a new research model.

    Area of Science:

    • Veterinary Medicine
    • Endocrinology
    • Urology

    Background:

    • Benign prostatic hyperplasia (BPH) is common in older male dogs.
    • Hormonal influences are suspected in the development of BPH.
    • Previous studies have explored various hormonal treatments.

    Purpose of the Study:

    • To review the hormonal etiology of BPH in humans and dogs.
    • To investigate the efficacy of specific hormones in inducing canine BPH.
    • To establish a potential experimental model for studying BPH pathogenesis.

    Main Methods:

    • Review of existing evidence on hormonal etiology of BPH.
    • Experimental administration of testosterone, dihydrotestosterone, estradiol, and androstanediol to dogs.
    • Observation and characterization of induced prostatic changes.

    Main Results:

    • Testosterone, dihydrotestosterone, or dihydrotestosterone plus estradiol did not induce BPH in dogs.
    • Androstanediol, alone or with estradiol, induced features characteristic of canine BPH.
    • This suggests a specific hormonal pathway involved in canine BPH.

    Conclusions:

    • Androstanediol plays a significant role in the development of canine BPH.
    • The findings provide a valuable experimental model for BPH research.
    • Further investigation into androstanediol's role could reveal new therapeutic targets.
