Evolutionary theories of the female orgasm in humans tend to neglect comparative approaches to understanding the evolutionary history of the human female orgasm. New theory followed up by experimental evidence, however, is changing this. 1/
In 2016 researchers proposed that the female orgasm in humans, which is more likely to be induced via clitoral stimulation, may have been necessary and functional -- to induce ovulation in females -- further back in mammalian evolutionary history. 2/ onlinelibrary.wiley.com/doi/pdf/10.100… 
In many mammals the clitoris is located in or closer to the vagina, making orgasm more likely & more closely tied to reproduction. BC of genetical arrangement changes over evolution, human female clitoris' are further away from vagina, reducing the likelihood copulation-orgasm 3/
A new experimental study IN RABBITS tested this hypothesis by giving rabbits prozac to decrease the likelihood of orgasm, which then led to a 30% reduction in ovulation post-copulation. Overall the 'evolutionary origins' hypothesis is receiving support. 4/ pnas.org/content/116/41…
Although this evidence IN RABBITS supports the 'evolutionary origins' theory of female orgasm, bad #scicomm showing human females with misleading headlines should be avoided /end phys.org/news/2019-10-f…
+ Collectively, these results suggest that the human female orgasm may in fact be a byproduct of a time when female orgasm was needed to induce ovulation. Spontaneous ovulation developed in humans, rendering the orgasm’s original ovulation function useless. /2nd end
