.... Summary: Our work found that oviductal fluid enhances sperm dynamics and survival and mitigates the negative effects of increasing temperatures on sperm in an ectotherm model. Sperm dynamic Sperm motility Temperature Oviductal fluid Global warming Increased global surface temperatures...

... Y227N males, Best1 protein was significantly reduced in testis and almost absent in homozygous mutant mice, although mRNA transcription of wild-type and knock-in allele is present and similar in quantity. Degradation of mutant Best1 protein in testis was associated with adverse effects on sperm motility...
