However, there is no evidence on the impact of aging on semen quality in men residing in Libreville, Gabon. Objective: To determine the effects of age on semen quality of patients visiting the Reproductive Laboratory at the Academic Hospital Mère Enfant located in Libreville, Gabon. Methods: This descriptive and prospective study was performed between the 1st of October 2021 and 30st of September 2022. This study involved patients who had semen analysis as part of fertility check-up. Semen analysis was performed following the World Health Organization, 2010 guidelines. Semen parameters such as volume, leucocytes count, sperm concentration, sperm motility, norml morphology and vitality were used in the current study. Descriptive statistics were performed. The Chi-square test and the Fisher test were used as statistical tools for the analysis of data. The ROC curve was used to illustrate the data. Results: A total of 148 patients were included in the study. Male infertility prevalence was 77.03%. The average age was 41 years with minimum and maximum of 24 and 61 years respectively. Secondary infertility was predominant (66.9%). Patients displaying asthenozoospermia (22.3%) followed by those displaying oligoasthenozoospermia (OAT) isolated (1.4%) or not (11.6%) were the most frequent semen parameter abnormalities. Men aged more than 45 years were 4.4 times likely to have abnormal semen parameters. Odd = 4.4 (IC 95% = [3.3 - 14.7]). Staphylococcus haemolyticus infection was more prevalent. Conclusion: Male age was found to significantly influence semen quality.展开更多
