This dual bony origin explains its unique ability to both adduct and extend the hip, and it is clinically relevant for groin pain, hamstring injuries, and neurovascular anatomy.

The adductor magnus originates from two distinct anatomical regions of the (specifically the pubis and ischium). It is traditionally described as having two parts: the adductor (pubofemoral) portion and the hamstring (ischial) portion .

The adductor magnus muscle is a bipennate muscle, meaning it has two sets of fibers that converge to form a single muscle belly. The adductor part of the muscle is innervated by the obturator nerve (L2-L4), while the hamstring part is innervated by the tibial nerve (L5-S2).
