Ferroptotic- and non-ferroptotic mechanisms associated with doxorubicin-induced male reproductive dysfunction

Area of Science:

• Reproductive Toxicology
• Oncology
• Cell Death Mechanisms

Background:

• Doxorubicin (DOX) is a vital chemotherapy drug but causes significant toxicity to male reproductive organs.
• Understanding the mechanisms of DOX-induced male reproductive dysfunction is crucial for patient care.

Purpose of the Study:

• To review and synthesize current evidence on ferroptotic and non-ferroptotic mechanisms of DOX-induced male reproductive toxicity.
• To explore potential protective strategies and the need for fertility preservation.

Main Methods:

• Literature review synthesizing existing research on doxorubicin's effects on male reproductive health.
• Analysis of cellular and molecular pathways involved in doxorubicin toxicity.
• Examination of emerging evidence on ferroptosis and antioxidant interventions.

Main Results:

• DOX induces testicular damage via oxidative stress, lipid peroxidation, mitochondrial dysfunction, and apoptosis in key testicular cells.
• DOX disrupts the hypothalamic-pituitary-gonadal (HPG) axis, impairing testosterone production and spermatogenesis.
• Ferroptosis is identified as a significant contributor to DOX-induced testicular injury, with potential protective roles for antioxidants like melatonin and zinc oxide nanoparticles.

Conclusions:

• DOX-induced male reproductive dysfunction involves complex ferroptotic and non-ferroptotic pathways.
• Antioxidant therapies show promise for mitigating DOX-induced testicular damage.
• Integrative care approaches are essential for managing cancer treatment side effects and preserving fertility.
