Ageratum conyzoides Extract Ameliorates Testosterone-Induced Benign Prostatic Hyperplasia via Inhibiting Proliferation, Inflammation of Prostates, and Induction of Apoptosis in Rats

, an annual herbaceous plant that inhabits tropical and subtropical regions, has been traditionally used in Asia, Africa, and South America for phytotherapy to treat infectious and inflammatory conditions. However, the pharmacological effects of standardized ethanolic extract of (ACE) on benign prostatic hyperplasia (BPH) remain unexplored. The objective of this research is to examine the potential physiological impacts of ACE, a traditionally utilized remedy for inflammatory ailments, in a rat model with BPH induced by testosterone propionate (TP). Rats were subcutaneously administered TP (3 mg/kg) to induce BPH and concurrently orally administered ACE (20, 50, and 100 mg/kg) daily for 42 days. ACE markedly improved BPH characteristics, including prostate weight, prostate index, and epithelial thickness, while also suppressing androgens and related hormones. The findings were supported by a decrease in androgen receptor and downstream signals associated with BPH in the prostate tissues of the ACE groups. Furthermore, increased apoptotic signals were observed in the prostate tissue of the ACE groups, along with heightened detection of the apoptotic nucleus compared to the BPH alone group. These changes seen in the group that received finasteride were similar to those observed in this group. These findings suggest that ACE shows promise as an alternative phytotherapeutic agent for treating BPH.
