Background:

Lycopene, a highly unsaturated carotenoid with exceptional antioxidant capacity, has emerged as a pivotal bioactive compound in the nutritional pharmacology of male health.

Beyond its classical free radical–scavenging role, lycopene orchestrates a coordinated regulation of oxidative, endocrine, and inflammatory pathways - forming a unified Redox–Endocrine–Reproductive Axis that underlies multiple male disorders, including infertility, erectile dysfunction, benign prostatic hyperplasia (BPH), and prostate cancer.

Methods:

A comprehensive synthesis of molecular, preclinical, and clinical evidence was performed to elucidate lycopene’s mechanistic roles and translational outcomes.

The review integrates findings from randomized controlled trials (RCTs), meta-analyses, and professional consensus statements, emphasizing mechanistic continuity across the antioxidant, hormonal, and genomic domains.

Dose rationality and multi-nutrient synergy (with L-arginine, Serenoa repens, selenium, Coenzyme Q10, and vitamin–mineral complexes) were evaluated within the framework of nutritional pharmacology.

Results:

Evidence demonstrates that lycopene at 40 mg/day achieves systemic modulation across the male health spectrum.

It re-establishes endothelial nitric oxide (NO) signaling, enhances testosterone synthesis, inhibits 5-α-reductase and dihydrotestosterone (DHT) over-activity, and attenuates NF-κB–driven inflammation.

These mechanisms collectively improve sperm quality, erectile performance, prostatic volume, and oxidative genomic stability.

Epidemiological and interventional studies further confirm its preventive efficacy against prostate cancer, correlating higher plasma lycopene concentrations with reduced tumor aggressiveness and PSA levels.

The nutrient also exhibits synergistic benefits when co-administered with L-arginine and selenium, completing a closed-loop regulation of vascular, endocrine, and reproductive axes.

Conclusions:

Lycopene functions as a systemic homeostatic regulator rather than a single-pathway antioxidant.

Through its tri-axis modulation of redox, hormonal, and inflammatory networks, it provides an evidence-based nutritional intervention for infertility, erectile dysfunction, BPH, and prostate cancer prevention.

With robust clinical validation, excellent safety up to 75 mg/day, and universal consensus around the 40 mg/day therapeutic benchmark, lycopene exemplifies the paradigm of precision nutritional pharmacology - transforming men’s health management from symptomatic relief to molecular-level restoration of biological equilibrium.
