The PSA test and digital rectal exam (DRE) may be used to screen both asymptomatic and symptomatic men for prostate cancer. PSA is a protein produced primarily by cells in the prostate and most of the PSA is released into semen, but small amounts of it are also released into the blood. PSA exists in two forms in the blood: free (not bound) and complexed (cPSA, bound to other proteins).

The slang word flapper, describing a young woman, is sometimes supposed to refer to a young bird flapping its wings while learning to fly. However, it may derive from an earlier use in northern England to mean teenage girl, referring to one whose hair is not yet put up and whose plaited pigtail flapped on her back; or from an older word meaning prostitute.
