“…In a group of 38 infants delivered prematurely following low oestrogen excretion, however, only four died in the neonatal period, whereas in a comparable group of 21 patients whose deliveries were not induced 14 infants died soon after birth (Heys et al, 1968). With regard to neurological handicaps Greene et al (1969), in a careful study with suitable control patients, showed that delivery after subnormal oestrogen excretion did not predispose to developmental problems in comparison 88 with infants matched for birth weight and gestation period.…”
