Some of this might not be accurate. "Human testes are on average 0.06 percent of body weight and sperm concentration is about 25 million per ejaculate." 25 million per ejaculation would fall in the "low" fertility category. At the other end of the range you can have 10x that amount. The part about bee phallus implantation is true, but to my knowledge it does not really deter others (in honey bees at least). The queen mates with multiple males and has offspring using genetics from more than one.
