Prostate origin describes the embryologic and anatomical origin of the prostate gland. In human development, the gland arises from endodermal prostatic buds that sprout from the prostatic portion of the urogenital sinus under the influence of androgens produced by the fetal testes. This epithelial growth is guided by interactions with surrounding mesenchyme, leading to ductal branching and differentiation into mature acini. The mature gland develops its characteristic fibromuscular stroma, and the glandular tissue forms the three functional zones of the adult prostate: peripheral, central, and transitional.

Anatomy and histology: The prostate surrounds the proximal urethra just below the bladder. It consists of tubuloalveolar glands lined by secretory epithelium, supported by smooth muscle stroma. Secretions contribute to seminal fluid, including citrate and zinc, and are released through ducts into the prostatic portion of the urethra. Prostate-specific antigen (PSA) is produced by prostatic epithelial cells and is used clinically as a marker of prostate health.

Clinical relevance: The most common cancer arising from the prostate is prostatic adenocarcinoma, which originates from glandular epithelium and often develops in the peripheral zone. Risk factors include age, ethnicity, family history, and certain gene mutations (such as BRCA1/2). Knowledge of the gland’s embryologic origin informs understanding of congenital prostate or urethral anomalies and the biology of prostate diseases.
