Birth weight in pregnancies after induction of ovulation with pituitary gonadotrophins.

Birth weights offer a means of determining normality of babies born after induction of ovulation with human pituitary gonadotrophins. A study of 62 patients treated under the auspices of the Australian Human Pituitary Advisory Committee shows that birth weights of the babies were not significantly different from those in two large Australian obstetric populations. Multiple pregnancies are more common after ovulation induction. Birth weights in twins are approximately 85% of those in singleton pregnancies.
