Bacterial load in AV equipments, buffer and extender in two different phases of study.
| Name of material | Number of samples | Phase I (bacterial load as CFU/plate) | Phase II (bacterial load as CFU/plate) | Significant level | ||
|---|---|---|---|---|---|---|
| Range (minimum-maximum) | Mean±SEM | Range (minimum-maximum) | Mean±SEM | |||
| AV liner | 36 | 1-3 | 2.33a±0.67 | 0-1 | 0.50b±0.52 | 0.001 |
| Cone | 36 | 0-7 | 4.16a±1.20 | 1-3 | 1.91b±0.55 | 0.001 |
| Semen collection tube | 36 | 0 | 0 | 0 | 0 | |
| Other glassware (flasks, beakers, pipettes etc.) | 36 | 0 | 0 | 0 | 0 | |
| Buffer | 14 | 0 | 0 | 0 | 0 | |
| Extender | 14 | 0-2 | 1.33a±0.38 | 0 | 0b | 0.001 |

Values with different superscript in column 4 and 6 differ highly significantly (p<0.001), SEM=Standard error of mean, CFU=Colony forming unit, AV=Artificial vagina
