Abstract The number of eggs fertilized by a male at any
given copulation (fertilization success) is affected by a
large number of factors. Male insemination and sperm
competition success and various female structures and/or
processes that bias paternity in favor of some males over
others (cryptic female choice) are all likely to affect
fertilization success. We suggest that more comprehen-
sive measures of male fertilization success can increase
our understanding of postcopulatory sexual selection. To
improve our understanding of the importance of various
sources of variance in male fertilization success, we
