Vitamin C is an antioxidant that suppresses the oxidative stress caused by cigarette smoke purpose of this study demonstrate whether vitamin C can provide a different quality of sperm male mice Mus musculus L are given exposure to cigarette smoke. Methodology: The study subjects are 32 male mice Mus musculus L, which were randomly divided into 2 groups. The first group was the control group (K) who received treatment exposure from cigarette smoke without giving vitamin C and the second group is the treatment group (P) are given exposure from cigarette smoke and vitamin C dose of 0.40 mg / gBB /day. The treatment during 30 days, on day 31 the mice were terminated, and then examined the quality of spermatozoa motility of spermatozoa, sperm concentration and morphology of spermatozoa. Results: Test oneway ANOVA on the mean motility of spermatozoa showed Ma control group (47,38%), Mb (11,88%), Mc (18,13%), Md (22,63%) and the Ma treatment group (11.68%), Mb (17,04%), Mc (35,77%), Md (16,5%). The mean concentration of spermatozoa obtained 63,34x105/ml control group and the treatment group and the mean morphology of spermatozoa 81,75x105/ml control group showed normal morphology 50% and abnormal morphology 56,189% while the treatment group showed normal morphology 60% and 40% abnormal. Result from Oneway ANOVA test there are differences significant in the morphology of spermatozoa, concentration of spermatozoa, sperm concentration, and sperm morphology between groups (p <0,05). Conclusion: Vitamin C can improve the quality of spermatozoa after exposure to cigarette smoke.

Metodologi: Subyek penelitian 32 ekor mencit jantan Mus Musculus L, yang dibagi secara acak menjadi 2 kelompok. Kelompok pertama adalah kelompok kontrol (K) yang mendapat perlakuan paparan asap rokok tanpa pemberian vitamin C dan kelompok kedua yaitu kelompok perlakuan (P) yang diberi paparan asap rokok dan vitamin C dosis 0,40mg/gBB/hari. Perlakuan berlangsung selama 30 hari, pada hari ke-31 mencit tersebut diterminasi, kemudian dilakukan pemeriksaan kualitas spermatozoa yaitu motilitas spermatozoa, konsentrasi spermatozoa dan morfologi spermatozoa. Hasil: Uji oneway ANOVA pada rerata motilitas spermatozoa kelompok kontrol menunjukan Ma(47.38%), Mb(11.88%), Mc(18.13%), Md(22.63%) dan kelompok perlakuan Ma(11.68%), Mb(17.04%), Mc(35.77%), Md(16.5%). Rerata konsentrasi spermatozoa kelompok kontrol didapatkan 63.34x105/ml, dan kelompok perlakuan 81.75x105/ml dan rerata morfologi spermatozoa kelompok kontrol menunjukkan morfologi normal 50% dan morfologi abnormal 56,189% sedangkan kelompok perlakuan menunjukkan morfologi normal 60% dan abnormal 40%. Hasil Uji oneway ANOVA terdapat perbedaan yang signifikan pada konsentrasi spermatozoa yaitu morfologi spermatozoa, konsentrasi spermatozoa, dan morfologi spermatozoa antar kelompok (p<0.05). Kesimpulan: Pemberian vitamin C dapat memperbaiki kualitas spermatozoa setelah pemaparan asap rokok. Kata kunci: Rokok, vitamin C, kualitas spermatozoa.
