Males treated with 3,000 r-units were repeatedly mated on the day of the treatment, on the sixth day, the seventh day, the twelfth day and the nineteenth day thereafter. A drop in the percentage of dominant lethals was not observed until the nineteenth day, indicating that the sperm which was immature at the time of the treatment does not become available until some time after 12 days. Our evidence indicates that individual males vary considerably and suggests that the less affected sperm becomes available between 15 and 19 days after treatment, provided the sperm which was mature at the time of treatment has previously been used. When males copulated for the first time on the nineteenth day after the treatment two copulations did not exhaust the old sperm. The data show that the fully matured sperm available for immediate transfer may become exhausted in a few consecutive matings.
