Purpose: The present study was designed to investigate the inhibitory efficacy of aqueous and ethanolic extracts of Ageratum conyzoide L. (AC, Family asteraceae) on testosterone induced BPH in male mice. Materials and Methods: Mice were randomly divided into five groups (n=6): negative control group received corn oil, BPH model group receive testosterone (5mg/kg/day, S.C) dissolved in corn oil. Another group received standard BPH drug finasteride (5 mg/Kg/day, I.P) along with testosterone injection (5mg/kg/day, S.C). The other two group of animals received either aqueous or ethanolic AC plant extracts (100, 500. 1000 and 2000 mg/kg, I.P) along with testosterone (5mg/kg/day, S.C) consecutively for 28 days. All animals were sacrificed at the end of the study period and prostate weight and prostatic index were determined, followed by histolopathological examination of the prostate gland. Results: The result of the present study indicated that treatment with either plant extracts caused significant reduction in prostate weight and prostatic index when compared to only testosterone treated animal group. The percentage of inhibition of prostate growth was found to be correlated in a dose dependent manner in plant extract treated groups. Histopathological examination of prostate gland revealed AC plant extracts treatment significantly reduced the glandular hyperplasia, epithelial thickness and stromal hyperplasia in the prostate gland of the treated animals. No significant elevation in serum ALT and creatinine level was recorded in any groups during the study period. Conclusion: This study hence indicate the therapeutic potential in Ageratum conyzoides L. plant extract in testosterone induced BPH model in mice.

Background: The study was aimed at screening phytochemicals and evaluating the effects of aqueous and 50\% (v/v) methanol stem bark extracts of Newtonia hildebrandtii on male rat reproductive system. Materials and Methods: Thirty male Wistar rats were divided into five groups and were given different treatments of N. hildebrandtii extracts at 200 and 400 mg/kg body weight. After 8 weeks, body and right testis weight, sperm concentration, hormonal levels, and histological structure of the testis were evaluated. Calorimetric method was used for quantitative analysis of phenolic compounds, whereas gas chromatography{\textendash}mass spectrometry (GC-MS) was used for fingerprinting of chemical compounds. Results: Testosterone, luteinizing hormone, estradiol, and follicle-stimulating hormone levels were significantly increased, whereas prolactin levels were significantly decreased in the treated groups compared to the control. Sperm parameters were significantly increased compared to the control. Treated animals showed significant increases in body weight, seminiferous tubule diameter, and germinal epithelial height with the testes showing all the stages of spermatogenesis. Phytochemical screening of the methanolic extracts revealed the presence of alkaloids, carbohydrates, reducing sugars, steroids, anthraquinones, flavonoids, phenols, and saponins. GC-MS analysis revealed the presence of dimethylsilanediol; (R, R)-2,3-butanediol; hexamethylcyclotrisiloxane; succinimide; 1H-1,2,3-triazole-4-carboxylic acid, 1-(4-amino-1,2,5-oxadiazol-3-yl)-5-ethyl-, ethyl ester; l-(+)-ascorbic acid 2,6-dihexadecanoate; cis-13,16 docasadienoic acid, methyl ester; 9-octadecenoic acid (Z)-, 2-hydroxy-1-(hydroxymethyl) ethyl ester; and 2-chloro-benzoic acid N{\textquoteright}-[2-(3-oxo-3,4-dihydro-2H-benzo[1,4]thiazin-2-yl)-acetyl]-hydrazide. Conclusion: N. hildebrandtii appears to possess androgenic and anabolic effects. The aforementioned phytochemicals seem to be responsible for its aphrodisiac effects. This study supports the ethno-aphrodisiac claims that have been made against it.
