عنوان انگلیسی L-Carnitine and Pentoxifylline Supplementation Improves Sperm Viability and Motility at Low Temperature
چکیده انگلیسی مقاله Background: In infertility clinics, preserving high-quality spermatozoa for a long time is a necessity. Pentoxifylline (PT) and L-carnitine (LC) are effective in improving sperm motility as well as protecting the sperm membrane. The present study aimed to investigate the protective impacts of PT and LC on the quality of the normal sperm motility, protamine content, and viability on prolonged storage for 12 days at 4-6°C.
Materials and Methods: The present experimental work included 26 samples, which were first prepared based on the swim-up technique, of normozoospermic men. They were divided into three aliquots as untreated control, LC-treated, and PT-treated groups and incubated for up to 12 days at 4-6°C. Thereafter, chromatin maturity, sperm viability, and motility were assessed on 0, 1, 2, 5, 7, and 12 days. Data were analyzed using a one-way analysis of variance.
Results: The obtained data revealed that PT supplementation increased the percentage of motile spermatozoa in comparison with control and LC-treated specimens. On the other hand, LC supplementation increased the percentage of viable spermatozoa in comparison with the PT-treated and control samples. During the 12-day storage, the percentage of spermatozoa with a normal protamine content was nearly unchanged in the three groups (P>0.05).
Conclusion: Although LC supplementation can be considered a better alternative than PT for preserving sperm viability, PT could better preserve sperm motility compared to LC during 12 days at 4-6°C.
