In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. [ 1 ] [ 2 ] This is an aspect of mating . Many aquatic animals use external fertilization , whereas internal fertilization may have developed from a need to maintain gametes in a liquid ...
Lordosis behavior (/ l ɔːr ˈ d oʊ s ɪ s / [1]), also known as mammalian lordosis (Greek lordōsis, from lordos "bent backward" [1]) or presenting, is the naturally occurring body posture for sexual receptivity to copulation present in females of most mammals including rodents, elephants, cats, and humans.
In non-primates, copulatory calling predominantly occurs before copulation in order to attract mates (mating call). Calls vary in frequency (14 Hz [4] to 70,000 Hz [5]) and function. One of the main purposes of females vocalizing is the induction of mate guarding behavior in males. [6]
Post-copulatory behavior [ edit ] Sperm competition among males is induced due to copulatory plug, as the primary function of the plug is to prevent re-mating in females by maintaining a reproductive barrier that blocks the female cloacal opening for about 72 hours after mating.
In groups such as dragonflies and many spiders, males extrude sperm into secondary copulatory structures removed from their genital opening, which are then used to inseminate the female (in dragonflies, it is a set of modified sternites on the second abdominal segment; in spiders, it is the male pedipalps).
Mate binding refers to a pre-copulatory courtship behavior where the male deposits silk onto the abdomen of the female while simultaneously massaging her in order to reduce her aggressive behavior. This action allows for initial and subsequent copulatory bouts. [7]
It’s entirely possible he drew on the teachings of Dr. Sigmund Freud, whose theories on psychosexual behavior ruled the day. Freud believed that the clitoral orgasm was immature and infantile. “Elimination of clitoral sexuality is a necessary precondition for the development of femininity,” Freud opined, “since it is immature and ...
Mate guarding is a common defensive post-copulatory behavior in birds. It is a behavior in which males attempt to prevent cuckoldry. Males that exhibit higher levels of mate guarding behavior have a higher chance of paternity following copulation. [5]
