Article Title: Effects of ultraviolet B radiation and cold storage on Ram sperm morphology and physiology
doi: 10.1007/s00484-025-03082-4
Figure Lengend Snippet: Mean values (± SEM) of total motility of ram spermatozoa immediately after UVB exposure (0 h – blue), and after 24 h (green) and 48 h (red) of cold storage at 5 °C. Sperm samples were evaluated following exposure to UVB radiation at different time intervals (0, 30, 60, 90, 120, and 150 s). Different lowercase letters above the bars indicate statistically significant differences ( p < 0.05) within each storage timepoint, i.e., differences between exposure times at 0 h, 24 h, and 48 h, respectively. Radiation 0 s = 0; 30 s = 2.199 mJ/cm2; 60 s = 4.398 mJ/cm2; 90 s = 6.597 mJ/cm2; 120 s = 8.796 mJ/cm2; 150 s = 10.995 mJ/cm2
Article Snippet: Radiation was delivered using a UVB lamp (VL-115 C, 30 W, peak emission at 312 nm; Vilber Lourmat, Marne Lavallée, France), positioned at a fixed distance from the samples.
