Male fetal pigs have an urogenital opening located behind the umbilical cord. The swelling behind the hind legs of the fetal pig [ 24 ] is the scrotum .

The head (or the buttocks in a breech birth) of the baby is pushed against the cervix, which gradually dilates until it is fully dilated at 10 cm diameter. At some time, the amniotic sac bursts and the amniotic fluid escapes (also known as rupture of membranes or breaking the water). [3]
The presenting fetal part then is permitted to descend. Full dilation is reached when the cervix has widened enough to allow passage of the baby's head, around 10 cm dilation for a term baby. A standard duration of the latent first stage has not been established and can vary widely from one woman to another.
