Literature retrieved from Pub Med database showed reports of 7 other cases of NLE following ovulation induction and IVF. Flare-up of lupus activity in women following ovulation induction is documented and rates are higher after gonadotrophins than after clomiphene therapy [3,4]. Awareness of this and its associated maternal and fetal complications will increase the safety of artificial reproduc...

A report of a high incidence of genetic abnormality after in vitro fertilisation' led to a suggestion that the apparently low fecundity in man' may be partly explained by a high incidence of loss of embryos due to genetic factors. Data from induction of ovulation in patients with hypogonadotrophic hypogonadism, however, suggest that a high incidence of conception may be achieved.3 Advances in u...
