    Human prostate contains high levels of inhibin, a protein also found in seminal plasma. Elevated inhibin in benign prostatic hypertrophy suggests its potential as a biomarker for monitoring prostate diseases.

    Area of Science:

    • Endocrinology
    • Urology
    • Biochemistry

    Background:

    • Inhibin, a protein hormone, plays a role in reproductive functions.
    • Previous research has primarily focused on inhibin's presence in the testes and seminal plasma.

    Purpose of the Study:

    • To investigate the presence and concentration of inhibin-like protein in the human prostate.
    • To compare prostate inhibin levels with those in other tissues and in different prostate conditions.

    Main Methods:

    • Partial purification of inhibin-like protein from human prostate tissue.
    • Comparison of inhibin concentration and activity in prostate, seminal plasma, and testis.
    • Analysis of inhibin levels in normal, cancerous, and benign prostatic hypertrophy (BPH) tissues.

    Main Results:

    • Inhibin-like protein from the prostate showed similarities to that from seminal plasma.
    • Prostate tissue exhibited a tenfold higher concentration of inhibin compared to testicular tissue.
    • Benign prostatic hypertrophy (BPH) tissue demonstrated a tenfold increase in inhibin concentration relative to normal or cancerous prostate tissue.

    Conclusions:

    • The human prostate contains significantly high levels of biologically and immunologically active inhibin, a finding unique in humans.
    • Elevated inhibin levels in BPH suggest its potential as a diagnostic or therapeutic marker for prostate diseases.
    • Serum inhibin determination may serve as a valuable tool for monitoring prostate disease progression and treatment efficacy.
