Effect of consumption of aqueous extract of green tea for 52 days on sperm velocity parameters of male Wistar rats.
| Control | 2% Green tea | 5% Green tea | |
|---|---|---|---|
| VSL (µm/s) | 51.7 ± 8.6 | 59.6 ± 3.0 | 61.4 ± 10.7 |
| VCL (µm/s) | 274.0 ± 18.9 | 297.5 ± 20.9 | 274.9 ± 37.7 |
| VAP (µm/s) | 99.2 ± 8.9 | 113.0 ± 7.0 | 105.7 ± 12.7 |
| ALH (µm) | 10.3 ± 0.4 | 10.8 ± 0.3 | 10.1 ± 0.8 |
| LIN (%) | 18.5 ± 1.9 | 20.2 ± 0.6 | 22.1 ± 1.8 |
| STR (%) | 51.9 ± 4.0 | 53.0 ± 1.6 | 57.1 ± 4.9 |
| WOB (%) | 36.1 ± 1.0 | 38.1 ± 0.5 | 38.9 ± 0.8 |
| BCF (Hz) | 6.4 ± 0.6 | 6.1 ± 0.3 | 7.3 ± 1.1 |
Values represented are the means ± SEM of 6 animals per group, and 200 sperm per animal were analysed.
VSL straight-line velocity, VCL curvilinear velocity, VAP average path velocity, ALH the amplitude of lateral head displacement, LIN linearity, STR straightness, WOB wobble, BCF beat cross frequency.
