description: At birth, newborns are endowed with maternal antibodies. IgG production normally begins at the age of two months. A delay in recovery from this physiological hypogammaglobulinemia between the 3rd and the 6th month of life, and of recovery period between 18 and 36 months defines transient newborn hypogammaglobulinemia.
