Do certain animals experience sexual climaxes?
In the world of nature, critters large and small follow their instincts during the act of reproduction. From a salmon battling upstream to a turtle balancing on a shoe, everything obeys the call that sets them in motion. The burning question, though, is whether these creatures feel something akin to what we humans call an orgasm?
There's no definitive list out there of animals that orgasm, and that's because research on physiological and neurological activity during mating primarily focuses on primates and rodents. As mentioned by David Puts, a professor of anthropology and psychology at Penn State, we can't actually know for sure if animals experience the same intensity of pleasure we do during climax.
However, we can compare observed behaviors. Many female primates exhibit characteristics similar to those experienced by women during orgasm, such as a tightening of muscles, changes in facial expressions, shifts in respiration rates, vocalizations, and contractions of the vagina, anus, pelvic muscles, and uterus.
In males across the mammalian kingdom, similar activation patterns can be seen, although it's important to note that the definition of an orgasm has evolved through time to encompass both the physiological process and the characteristic experience of intense pleasure. A 2016 paper published in the journal Socioaffective Neuroscience & Psychology defines the physical process as a spinal reflex leading to rhythmic muscle contractions of the pelvic floor and anus.
While our understanding of orgasms has primarily revolved around mammals, we can't rule out the possibility that non-mammals experience pleasure or have orgasm-like responses during sex. Scientists have left the door open for further exploration into the physiological and neurological reactions that might occur during sexual activity in other creatures like birds, reptiles, and amphibians.
Orgasms serve as a bridge between reproduction and reward. While we don't need to fully grasp their purpose to enjoy one, understanding the complex processes at play can provide fascinating insights into the natural world around us.

In the realm of animals, researchers have observed correlations between certain behaviors and the human experience of orgasm, particularly in primates and some male mammals. However, whether other creatures, like reptiles, birds, or amphibians, experience orgasm-like responses remains a fascinating and open question for scientific exploration, offering intriguing insights into the natural world.
