gynecoid pelvis /gī′nəkoid, jin′ək-/ [Gk, gyne + eidos, form; L, pelvis, basin] , a type of pelvis characteristic of the normal female and associated with the smallest incidence of fetopelvic disproportion. The inlet is nearly round, the sacrum is parallel to the posterior aspect of the symphysis pubis, the sidewalls are straight, and the ischial spines are blunt and do not encroach on the space in the true pelvis. It is the ideal pelvic type for childbirth. It is one of the four classic Caldwell-Moloy pelvic types. Also spelled gynaecoid pelvis.
