The therapeutic effects of oil-soluble hysterosalpingography contrast medium following water-soluble hysterosalpingography contrast medium.

Previous studies have revealed that patients who underwent hysterosalpingography (HSG) with an iol-soluble contrast medium (OSCM) rather than a water-soluble contrast medium (WSCM) had higher subsequent fertility rates. In this randomized prospective study, the fertility rates among 109 patients following HSG were found to be 31% (19/61) in the WSOM group and 38% (18/48) in the WSOM + OSCM group. No significant difference was noted between these two groups, whether their infertility was associated with endocrine factor, male factor, endometriosis, mechanical factor or some other unexplained factor.
