Although it's not a new study, I found many tidbits of information that I wasn't aware of, mostly in the details.

Turner (1937) has carefully worked out the reproductive cycle of Xiphophorus from the viewpoint of ova development, period of fertilization, and superfetation. The present study is concerned with the reproductive cycle in this fish from the viewpoint of spermatozoa viability, selection and competition and the duration of ova production. Experiments have been conducted to show the number of young that can be born during the reproductive activity of the female and to show the duration of life of spermatozoa within the female genital tract and the competition and selection involved.
