Changes

It is unclear whether the [[ridged band ]] simply plays backup for the [[glans]], or whether the two have different functions. The location of the retracted [[ridged band ]] on the erect penile shaft suggests that the difference is one of timing. Possibly, the [[foreskin ]] and its [[ridged band ]] are designed to ensure that sexual reflexes are triggered when, and only when, these structures are stretched during intercourse. The biological importance of the [[ridged band ]] to conception is self-evident, but there is still a major gap in our understanding of the relation between form and function of the [[penis]].
