Short summary
In our study, we attempted to introduce a new device for optimizing sperm-mediated gene transfer. We utilized X-tremeGENE™ HP reagent from the Roche company in bovines, and one-third of total spermatozoa were transfected. We also examined the effect of DMSO on increasing the efficiency of the sperm/DNA transfer to oocytes via IVF. We examined these two reagents in bovine spermatozoa for the first time, which can be considered as the novelty of our work together with its originality.
