This article relies heavily on one text; McConaghy, JR; Panchal, B (1 November 2016). "Epididymitis: An Overview.". American family physician. Both authors are general practitioners and neither has written other articles on Epididymitis. This one does not indicate the size of the cohorts involved in their study and itself refers to older research. Since this article is quite specialised, it would be useful to see a range of citations from more specific studies and specialist authors.
