Dataset-specific description

Sperm were collected dry from the gonopores of males and placed in a small vial and kept on ice until use. A 0.1% dilution from dry sperm was made to verify sperm motility, and then preserved in formalin to count sperm densities with a hemacytometer in order to calculate the amount of diluted sperm required to attain desired sperm-egg ratios and sperm densities for each treatment.
