A Combination of <i>Punica granatum</i> Fruit Rind and <i>Theobroma cacao</i> Seed Extracts Enhances Sexual Function in Aging Males in a Randomized, Double-blind, Placebo-controlled Study

<b>Introduction:</b> LN18178 is a standardized, synergistic combination of <i>Punica granatum</i> fruit rind and <i>Theobroma cacao</i> seed extracts, which has been reported to increase serum testosterone levels in young and aging males. <b>Methods:</b> The present 84-day randomized, double-blind, placebo-controlled study assessed the efficacy of LN18178 on the sexual function of aging male volunteers (age: 40-70 years; serum total testosterone: ≥ 300 ng/dL). The subjects with mild to moderate erectile dysfunction [5-item version of the International Index of Erectile Function (IIEF-5) scores 17-25] and low sexual desire (score < 3 on items 11 and 12 of IIEF) participated in this investigation. One hundred and twenty men were randomly allocated into either the LN18178 or placebo group (n=60); they took either 400 mg of LN18178 or a matched placebo capsule daily with breakfast. <b>Results:</b> Post-trial, the LN18178-supplemented participants reported significant (P < 0.05) improvements in total and domain scores of the Derogatis Interview for Sexual Functioning-Self Reporting Male (DISF-SR-M) questionnaire, as well as substantial improvements in IIEF-5 (International Index of Erectile Function-5) and erection hardness scores (EHS). Comparative analysis also revealed significant improvements in the multi-dimensional fatigue inventory (MFI) and general health survey (GHS) scores. LN18178 supplementation substantially (P < 0.05) increased the six-minute walk distance and hand-grip strength compared to placebo. The participants' hemato-biochemical parameters, urinalysis, and vitals were within the normal range. <b>Conclusion:</b> LN18178 enhances sexual function, libido and improves psychological well-being, as well as neuromotor function and general well-being in aging males. LN18178 supplementation is safe and well tolerated by the participants.
