title: The effects of frequent ejaculation on seminal spermatozoal number and calculation of daily spermatozoal output.
abstract: Spermatozoal depletion of the extra-gonadal reserve (EGR) has been monitored in 14 men by analysing ejaculates collected daily for 5 days. It has been concluded that EGR is stabilized within 2 days and that an estimate of daily spermatozoal output can be obtained either by averaging the values from days 3 to 5 or by using the day 5 value alone. This latter parameter may prove useful clinically.
