Protamines are proteins vital for sperm chromatin condensation, with their expression ratios linked to fertility in different species.
The study aimed to evaluate RNA quality and protamine gene expression in testis samples from wild-derived mice, preserved under various conditions over different time frames.
Results indicated that samples preserved in RNAlater® or NAP buffer at -80°C maintained RNA integrity and protamine expression effectively, even under less optimal conditions like room temperature for a week.
Probiotics have recently gained attention for their potential therapeutic effects, but their impact on reproductive health remains under-researched.
This study tested the effects of two probiotic mixtures on sperm quality in mice, comparing them to a control group that received physiological serum.
Results indicated that probiotic treatments resulted in a higher percentage of normal sperm and altered head shape, although they didn't significantly improve overall motility compared to controls, suggesting further research is needed.
