136. Intrauterine foetal growth retardation may be associated with the following except

(a) maternal drug addiction
(b) maternal smoking
(c) foetal viral infection
(d) regular maternal aspirin intake

Exact lines taken from chapter 14 of Williams obstetrics 22nd edition : read along :
Because aspirin is a potent prostaglandin inhibitor, there is a theoretical concern that fetal exposure could lead to premature closure of the ductus arteriosus. Despite this, and with the massive number of exposures, premature closure has not been reported. DiSessa and colleagues (1994) performed echocardiography from 15 to 40 weeks in 63 fetuses exposed to 60 mg of aspirin given daily to prevent preeclampsia. They consistently found normal ductus flow velocity and cardiac output. Acetaminophen also has not been associated with an increased risk of anomalies (Pastore and colleagues, 1999; Thulstrup and associates, 1999).
