To minimize higher order pregnancy 2-3 fertilized ova are placed in-utero in ART.
Neonates of higher order pregnancy have high infant mortality rate, especially in lower socio-economic strata.
For example, among family planning clinic clients, 35% reported that their last second or higher order pregnancy
was unintended (8% mistimed, 27% unwanted), whereas 64% of prenatal clinic clients reported that their current second or higher order pregnancy
was unintended (23% mistimed, 41% unwanted).
