Previous research [J. The present experiments assessed the contributions of anal scent gland and urinary odorants to these preferences. Sexually experienced, ovohysterectomized female and castrated male ferrets were injected daily with estradiol benzoate and testosterone propionate, respectively. When tested in an airtight Y-maze, subjects of both sexes preferred to approach volatile odors emitted from opposite- versus same-sex stimulus ferrets that were anesthetized and placed in the goal boxes, regardless of whether the anal scent glands of stimulus ferrets had been surgically removed or left intact.

Non-reproductive sexual behavior consists of sexual activities animals participate in that do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals , recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals. Observed non-procreative sexual activities include non-copulatory mounting without penetration, or by the female , oral sex, genital stimulation, anal stimulation, interspecies mating, and acts of affection. Lions are known to engage in sex to create bonds and interact with each other. Lions live in a social group known as a pride that consists of 2—18 females and 1—7 males.
Male scorpionflies use anal horns to hook a mate
These insects have a pair of stubby "horns" on their rear ends, which they use to grab onto reluctant females. In one species of scorpionfly, males have evolved a cunning technique to catch mates and prolong the process of copulation. Scorpionflies are insects that have a scorpion-like stinger on the tips of their abdomens — although they do not have pincers. In the genus Dicerapanorpa , the males also have a pair of stumpy "anal horns" a little forward of the stinger.
