May offend German to English Medical Medical (general) anatomy of the penis

This appears in an early 19th-century text which includes excerpts from an autopsy report on the body of what was then termed a hermaphrodite.

The text runs: 'Dicht unter dieser Furche entspringt mit zwei Schenkeln ein breites Frenulum, welches die Eichel mit einem weiten, den Hals derselben umgebenen, Praeputium verbindet.

Anatomy is not my forte and I'm feeling rather challenged by this. I have done as much research as my stomach can stand on this and would now appreciate the assistance of a medical mind.
Apologies if it is obvious to those in the know. And many thanks for any assistance.
