You covered a lot of information on physical impacts on libido, particularly on SSRIs.  Given how developed the Wikipedia page on Libido is, I think your section fills much of the remaining need on the topic.   The writing also matches the quality of the other sections on the Libido Wikipedia page, and it flows well.  Good Job!

You also cite a variety of academic research to build your section, which provides useful and relatively unbiased information.  I think this page and edits are in great shape.  Both the page and the new sections are well-developed and informative.
