The prevalence of male infertility is a well-known public health issue with majority of cases due to deficient sperm production of unknown origin. Studies have associated dietary habits with male factor infertility. Chrysophyllum albidum is a common plant that produces a popular fruit, widely consumed for its nutritional and medicinal values. This study investigates the effects of C. albidum fruit methanol extract on the reproductive functions of male Wistar rats. Ripe C. albidum fruit was extracted using methanol and subjected to phytochemical screening. Fifteen male Wistar rats (100-120 g) divided into three (n = 5) received distilled water (control), 1.0 and 6.4 g kg-1 day-1 extract, respectively, for 28 days via oral gavage. The sperm count, motility, percentage sperm aberration, histology of testes and epididymides were examined by microscopy. Serum levels of luteinising hormone (LH), follicle-stimulating hormone (FSH) and testosterone were quantified using ELISA. Data were analysed using ANOVA at p < 0.05 significance. Sperm count significantly increased in 6.4 g kg-1 day-1 extract. Serum testosterone level decreased in 1.0 and 6.4 g kg-1 day-1 extract. The architecture of sections of testes and epididymides showed anomalies. C. albidum fruit adversely altered reproductive functions of male Wistar rat.
