title: Reproductive time lost due to sexual union dissolution in San José, Costa Rica.
abstract: Abstract   It has long been recognized, on a theoretical level, that widowhood, divorce, and separation, if not immediately followed by re-marriage, could have a negative impact on fertility. Davis and Blake specifically identified the amount of reproductive time spent after or between unions as one of the eleven intermediate variables bearing immediately upon fertility.
