effectiveness testing of l-carnitine on the quality of spermatozoa and testosterone hormone in white rats (Rattus norvegicus) feeding with high fat

This study aims to determine the increase in the quality of spermatozoa and testosterone after giving L-carnitine to white rats (Rattus norvegicus). This study was conducted by giving L-carnitine as a treatment for 42 days in white rats with a dose variation of 100 mg/kg bw, 150 mg/kg bw, and 200 mg/kg bw and user controls as a comparison. The variables observed in this study were the quality of spermatozoa, namely: morphology, motility, viability, membrane integrity, and seeing the levels of the hormone testosterone. The research data were processed using a computer statistical program (SPSS 22.0 for Windows) using the One Way Anova test. The results showed that giving high doses of L-carnitine supplements for a long time could cause decreased spermatozoa quality, namely: morphology, motility, viability, membrane integrity and decreased levels of the hormone testosterone.
