Human Umbilical Cord Blood (hUCB) is considered as good sources of stem cells with least ethical issues as it is routinely discarded as waste material. Potential of these stem cells in treating neurodegenerative disorders and other blood related disorders has been already tested in animals and humans. After the first successful transplantation using hUCB in 1988 for reconstitution of hematopoiesis in a patient with Fanconianaemia, transplantation using hUCB derived stem cells has been used for the treatment of various diseases such as malignant and non malignant diseases. Though these multipotent stem cells have greater potential to differentiate into variety of cells but still the stem cells derived from single cord blood unit is not found to be sufficient for an adult transplantation. Yoga has been already shown to increase the stem cells in peripheral blood, it may have effect on UCB stem cells too and UCB derived stem cell efficacy may increase after practicing Yoga. Stems cells with the increased efficacy can be a great application for future transplantations for treatment of various life threatening disorders. Apart from stem cells, expectant mother suffer from many pregnancy related complications which can affect fetus and pregnancy outcome. There are many evidences of Yoga being a good mean to reduce stress, anxiety and depression and also reduce many pregnancy related complications. Therefore Yoga during pregnancy can be very effective in both reducing complications and increasing pregnancy outcomes
