Sutakashaucha

The impurity (ashaucha) caused by
childbirth (sutaka). All bodily effluvia
(hair, spittle, pus, blood, etc.) are
considered to be sources of impurity,
and because birth is attended with
these it is considered impure, even
though it is always regarded as an
auspicious and happy event. There is
also impurity caused by death, known as
maranashaucha, but the presence of
the corpse renders this impurity more
violent; needless to say, it is also considered inauspicious.
