A midwife is a professional in midwifery . Also known as obstetrics, midwifery is the health science and the health profession concerned with pregnancy, childbirth, and the postpartum period, besides sexual and reproductive health of women throughout their lives. The actual duties of the midwife are mainly to assist in the birthing process. It is said that the rates of obstetrical intervention in birth are rising worldwide. Although professional midwives attend the majority of births in some of these countries, they are biomedical socialized and often overworked, and have been unable to stem the rising cesarean tide, which is largely obstetrician-driven. Though both midwives and obstetricians have worked hard to preserve normal vaginal delivery in these countries the Scandinavian and Japan are the exceptions.
