"Certain females consume male ejaculate and sperm as if they were food, using the nutrients to fuel their own bodies as well as their eggs, The study, published in the journal Biology Letters, adds yet another dimension to the battle between the sexes.
â€œIf males have their sperm consumed, rather than used for egg fertilization, they will lose that reproductive opportunity. Therefore, it is in the maleâ€™s best interests to try to ensure at least some of his sperm reaches the femaleâ€™s eggs,â€� lead author Benjamin Wegener, a researcher at Monash Universityâ€™s School of Biological Sciences, explained to Discovery News.
Wegener said that ejaculate consumption is well documented among numerous species. Humans are included in that group, but the behavior is not a standard part of our reproductive process." - Discovery
