BackgroundCocos nucifera (Coconut, Arecaceae family) is consumed as dietary fruit but little is known of it as sex enhancer.ObjectiveTo investigate male sex hormones and copulation behavior indices in male Wistar rats administered husks extract.Materials And MethodsRats were grouped into control A, and treatment B to E (n=4); and administered husks extract at varying doses: 125mg/kg, 250mg/kg, 375mg/kg and 500mg/kg for 48days by oral intubation. Copulation behavior was assessed by introducing female rats to males (1:1) in a rectangular Plexiglas chamber and monitored by veterinary Anatomists. Blood samples for male sex hormones were collected and assayed by ELISA method.ResultsCopulation behavior (500mg/kg treatment): mounting (9.66±0.79 to 29.08±2.16), ejaculation (7.66±0.38 to 16.93±0.76), intromission (22.01±1.67 to 38.11±3.35) frequencies, and ejaculation latency (7.92±0.43 to 12.28±0.41) increased remarkably (Group E). Correspondingly, mounting (133.31±1.18 to 93.39±0.43) and, intromission (88.13±3.12 to 74.55±1.19) latencies; post-ejaculation (3.16±0.14 to 2.18±0.34), inter-intromission (19.48±0.26 to 14.32±1.65) intervals reduced significantly (P≤0.05). Testosterone levels (Group E) increased: 3.82±0.6ng/dL to 5.14±0.3ng/dL while, LH and FSH values reduced: 2.92±0.6IU/L to 2.13±0.3IU/L and 2.28±0.7IU/L to 1.58±0.3IU/L significantly (p ≤ 0.05) while changes were dose-related.ConclusionC. nucifera husks extract improves sexuality indices by regulating male sex hormones in male Wistar rats.© 2022 Odigie EB et al.
