ABSTRACT
Background: Cryopreservation techniques are highly developed field of Assisted Reproductive Technologies (ARTs) to help infertile couples to overcome infertility. Coenzyme Q10 (CoQ10) is a vitamin – like substance is present in most eukaryotic cell, and produced in the mitochondria primarily. Objective: To study the effects of CoQ10 supplemented to thawing solution on sperm parameters post- cryopreservation technique. Materials and Methods: One hundred and eight males were participated in this study. The mean age for all males included in this study was (29.94 ± 0.65) years and duration of infertility was 2-14 years. Semen samples were collected and seminal fluid analysis was done according to WHO (2010] All groups contain 1mL from semen sample mixed with 0.7 mL of cryopreservation
solution. All groups after thawing were divided into 3 subgroups (GA: control group; without honey bee), (GB: contain 5 μm from CoQ10) and (GC: contain 10 μm] Results: There was significant increase (P<0.05) in the progressive sperm motility (%), progressive sperm motility (%) grade (A), progressive sperm motility (%) grade (B) and normal sperm morphology when compared among groups (GA: control group), (GB:5 μm CoQ10 ),(GC:10 μm CoQ10] Significant reduction (P<0.05) in the percentages of sperm immobility (%) when compared to control group with GB and GC. In the present study appeared that the direct swim-up technique resulted in significantly (P<0.05) better results for sperm parameters than the swim-up technique from all types of ejaculates classified according to male infertility factors. The study proved that there was significant (P<0.05) improvement in sperm parameters. Conclusion: 10M COQ10 obtained best results for human sperm parameters post-thawing compared to other groups. Best technique in this study direct swim-up technique compared with centrifuge technique.
