Normal-weight eugonadic males served as controls. Participants were selected based on BMI and gonadal hormone levels.Interventions: Participants consumed two bags of green tea infused in 150 mL of boiled water daily for 12 weeks. Blood samples were collected at baseline, 1 month, and 2 months. Hormonal levels: luteinising hormone (LH), Follicle Stimulating Hormone (FSH), prolactin, testosterone, and oestradiol were measured using ELISA, while oxidative stress markers: malondialdehyde (MDA), total antioxidant capacity (TAC), and glutathione peroxidase (GPx) were analysed colourimetrically.Main outcome measures: changes in oxidative stress markers and reproductive hormone levels post-supplementation.Results: Obese participants had significantly higher MDA and lower TAC and GPx than controls (p&lt;0.05). Green tea significantly reduced MDA, oestradiol, and prolactin, whereas it increased TAC, GPx, and testosterone (p &lt; 0.05). LH and FSH were normalised in Eugonadic and Compensatory Hypogonadic groups but remained elevated in Hyper-gonadotropic Hypogonadism.Conclusions: Green tea supplementation reduced oxidative stress and improved hormonal balance in obese males, suggesting its potential for managing obesity-related reproductive dysfunction. Further studies should explore longterm effects.<\/jats:p>","DOI":"10.4314\/gmj.v59i4.8","type":"journal-article","created":{"date-parts":[[2026,1,12]],"date-time":"2026-01-12T13:31:31Z","timestamp":1768224691000},"page":"235-241","source":"Crossref","is-referenced-by-count":1,"title":["Green tea's impact on fertility hormones and oxidative stress markers in obese males with different gonadal statuses in Onitsha, Nigeria."],"prefix":"10.4314","volume":"59","author":[{"given":"Chikaodili","family":"N.
