Extract

The factors responsible for the return of fertility post-partum have not been very clearly defined. Several previous studies (Gross & Eastman, 1979; Diaz et al., 1988) have reported apparently major differences between populations in the duration of infertility associated with lactation. However, these differences may be related to the differences in study designs.
