Nelumbo nucifera Gaertn., also known as Indian lotus, is a large aquatic perennial plant with a long history of use in traditional medicine. According to reports, white N. nucifera petal extract has higher phytochemical compounds with the potential to improve sperm viability and to reduce oxidative stress compared with the red petal extract. Studies of the white N. nucifera petals on the male reproductive system are still not fully explored. This study aimed to determine how white N. nucifera petal tea affects the motility and viability of sperm in adult male rats. Four groups of eight male rats were created (n=8). The experimental groups 2-4 received various concentrations of white N. nucifera tea, while the control group (1) received distilled water. To determine sperm motility and viability, sperm suspension taken from the right caudal epididymis was examined under a light microscope. The results showed the number of motile sperm was significantly increased and the number of non-motile sperm was significantly lower in male rats given white N. nucifera tea at a dose of 0.55 mg/kg BW, when compared to the control group. However, the number of viable sperm did not differ significantly among groups. The indication of enhanced sperm motility can support the usage of white N. nucifera petal tea for improving sperm quality.
