A controversial aspect has been that of the rotation of the seminal doses. It is a practice routinely carried out on farms with the aim of preventing sperm sedimentation, in a medium considered “toxic” due to the accumulation of metabolic waste of the sperm cell.
To date, there are several publications dealing with the effect of rotation on the quality of seminal doses. Despite the fact that in the past it was believed to be beneficial (RODRÍGUEZ-GIL & RIGAU, 1995), the latest research has left evidence of the negative effect that this practice can have on seminal quality (SCHULZE et al., 2015), (MENEGAT et al., 2017). It is also believed that it can favor the loss of CO2 from the liquid phase to the air in the seminal doses, leading to accelerated alkalinization of the medium. This occurs with greater intensity with the use of short-term extenders, since buffers in their composition are simpler than in high-performance extenders.
