Absence of diurnal variation in semen parameters in normospermic men.
It has been previously suggested that semen parameters in men are subject to a significant diurnal variation, implying an advantage to performing IUI in the evening. Results of this prospective longitudinal study on 570 normospermic men suggest that the time of day that a sample is produced does not have an influence on semen parameters.
