Antihormonal therapy with tamoxifen (TAM), although standard in breast cancer management, is increasingly implicated in male reproductive toxicity through oxidative stress driven mechanisms. The Mediterranean shrub Pistacia lentiscus is rich in phenolic antioxidants with well documented free radical scavenging activity, yet its capacity to counter TAM induced gonadotoxicity has not been systematically explored.
To determine whether a methanolic extract of P. lentiscus (PL ME) can mitigate functional and biochemical indices of reproductive damage elicited by subacute TAM exposure in male mice. Adult Swiss albino males (8–10 weeks, 25–30 g) were randomized (n = 10/group) to four regimens for 20 days: (i) Control, (ii) TAM (30 mg kg⁻¹ p.o.), (iii) PL ME (1g kg⁻¹ p.o.), and (iv) TAM + PL ME (co treatment). Antiradical potency of PL ME was first confirmed by DPPH assay (IC₅₀ = 107 μg mL⁻¹). Post treatment, semen quality (concentration, motility, viability, morphology) was analyzed, together with pro oxidant markers: malondialdehyde (MDA), hydrogen peroxide (H₂O₂), and protein thiols ( SH) and also antioxidant enzymes: superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) in testis and epididymis.
TAM produced a marked decline in sperm concentration (40 %), motility (42 %), and viability ( 31%) while elevating head ( +12 %) and tail ( +20 %) deformities (p < 0.05). Concomitantly, testicular/epididymal MDA and H₂O₂ rose 2.3 to 2.8 fold, with a 48 % drop in SH. Antioxidant enzymes were paradoxically up regulated (SOD +46 %, CAT +72 %, GPx +88 %), indicating a compensatory yet insufficient response. Co administration of PL ME normalized seminal parameters (all p > 0.05 vs. control) and restored oxidative balance: MDA, H₂O₂, and SH returned to baseline, while SOD, CAT, and GPx activities were realigned within physiological ranges.
Pistacia lentiscus methanolic extract confers substantive protection against TAM induced male reprotoxicity by quenching lipid peroxidation, lowering peroxide burden, preserving thiol groups, and recalibrating endogenous antioxidant defenses. These findings highlight PL ME as a promising phytotherapeutic adjunct for safeguarding male fertility during antihormonal breast cancer therapy.
