The woman’s age is a definitive factor to achieve pregnancy. Certainly, in greater ages there is statistically lower frequency in successful gestations and birth rates of healthy babies. After the 43rd year of age, the successful percentage is only about 5%.
In rare cases, it is needed to make a vertical incision to the uterus. The baby is born within the first 10 minutes, during the rest of the time, the stitches to the uterine and abdominal wall will be done.
The decision about the kind of delivery depends many times according to the shape and presentation of the fetuses. The commonest presentation is cephalic/cephalic (50%), followed by cephalic/breech (25%), breech/cephalic (10%) and breech/breech (10%). 5% is a combination.
