In a manner relating to or affecting the genitals or reproductive organs; used to describe actions or conditions that concern reproductive anatomy.
From genital + '-ly' (adverb suffix), converting the adjective to an adverb to describe how something occurs or its manner of occurrence.
Words like 'genitally' reveal how English allows us to convert almost any anatomical term into an adverb, so doctors can write precise sentences like 'the patient was genitally examined' without ever using the word 'examined' alone.
