Abstract

Freeze-drying technique is an alternative method on sperm preservation. However, this process can results in DNA damage. Adding antioxidants before freezing can reduce the detrimental effects of ROS on spermatozoa. Alpha lipoic acid (ALA) is one of the potent antioxidant that can be used to protect the sperm DNA. This study was aimed to determine the effect of ALA supplementation before freeze-drying on the DNA fragmentation index (DFI) of human spermatozoa. Nine semen samples were collected and evaluated for DFI (O1) then divided into 3 groups; freeze-drying without ALA (O2), freeze-drying with ALA 1,25 mg (O3) and freeze-drying with ALA 2,5 mg (O4).All three groups were stored at 4oC for 1 week. Sperm DFI were evaluated before and after freeze-drying. The result of this study showed a significant increase in sperm DFI in all three groups after freeze-drying (p<0,05) when compared to DFI before freeze-drying (14,67 ±3,295). However there was no significant difference between O2 (26,90 ±9,180) and O4 (29,29 ±5,524) group where the supplementation of 2,5 mg ALA did not have significant effect on protecting the DNA of freeze-dried human spermatozoa. The highest DFI was in the O3 group (44,64 ±11,717). Therefore, ALA supplementation before freeze-drying does not have a significant effect on protecting the DNA of freeze-dried human spermatozoa.

Abstract

Congenital deafness will impact the quality of life of affected individuals if they do not obtain early detection and intervention. Socialization of congenital deafness is needed, thereby the community can engage in early detection and intervention efforts. Socializing about the early detection and intervention of congenital deafness. Educational activities are carried out with counseling using the lecture method, discussion, and pretest and posttest. The average pretest result was 62.03 (± 11.51) and the posttest average was 88.39 (± 13.41). Based on the comparison between the pretest and posttest results, we found a significant difference (p < 0.0001) statistically. Public knowledge of congenital deafness needs to be improved in order to increase community participation in terms of  early detection and intervention.
