It's a male!
This is a ventral view of a male fetal pig. Note the umbilical cord and the rows of nipples (mammary papillae). The anterior/cranial region is toward the top of the photo and the posterior/caudal region is toward the bottom.
Males do not have a urogenital papilla. Click here to see a closer view of the caudal region.
In the male, the urogenital tract opens near the umbilical cord. Click here to see a closer view of this area.
