Abstract

Background: Examining semen cryopreservation in Calomys laucha offers valuable insights for reproductive research and species conservation.

Objective: To determine the most effective sugar for the cryopreservation of C. laucha semen.

Materials and methods: Using 36 epididymides from C. laucha, semen samples were diluted in a 3% skimmed milk medium supplemented with one of four sugars (glucose, fructose, lactose, or sucrose) at a concentration of 0.3 M. These mixtures underwent a conditioning phase at 37 degree C for 10 min, cooled to -80 degree C for another 10 min, and were subsequently stored in liquid nitrogen.

Results: Upon thawing, samples treated with lactose and glucose solutions show superior sperm motility, achieving 8.2% and 10.0% respectively, in contrast to the fructose (2.0%) and sucrose (4.1%) mixtures. Furthermore, samples preserved in glucose registered the highest sperm penetration rates, reaching 44.9%.

Conclusion: Our findings suggest that a cryopreservation medium containing 0.3 M glucose can contribute to the safeguarding C. laucha rodent semen. https://doi.org/10.54680/fr24210110612.

优化 Calomys laucha 的精液冷冻保存：啮齿动物生殖研究的一大进步。

背景：研究Calomys laucha的精液冷冻保存为生殖研究和物种保护提供了有价值的见解：目的：确定冷冻保存乌贼精液最有效的糖：精液样本在 3% 脱脂奶培养基中稀释，培养基中添加浓度为 0.3 M 的四种糖（葡萄糖、果糖、乳糖或蔗糖）之一：解冻后，经乳糖和葡萄糖溶液处理的样本精子活力更强，分别达到 8.2% 和 10.0%，与果糖（2.0%）和蔗糖（4.1%）混合物形成鲜明对比。此外，在葡萄糖中保存的样本精子穿透率最高，达到 44.9%：https://doi.org/10.54680/fr24210110612。
