Abstract:
The effect of uterine leiomyoma on infertility is subject to controversy. Two main mechanisms associating leiomyomata and infertility have been suggested: the obstruction of gamete transport and impaired implantation. In-vitro fertilization (IVF) is a unique setting for examining the effect of leiomyomata on the implantation rate. This study was designed to determine the impact of uterine leiomyomata on the results of IVF. In a retrospective analysis of IVF cycles, 46 women with documented uterine leiomyoma were compared with a control group with mechanical infertility. The implantation rate and pregnancy outcome in relation to the leiomyoma were observed. Implantation (22.l%/transfer, 6.8%/embryo) and abortion rates (36%) in the study group were similar to the results in the control group with pure mechanical factor. An analysis of IVF results according to the hysteroscopic pretreatment findings revealed that impaired implantation is associated with leiomyoma only where uterine intracavitary abnormalities co-exist. We conclude that implantation rate and pregnancy outcome are impaired in women with uterine leiomyomata only when they cause deformation of the uterine cavity. In patients with leiomyomata associated with an abnormal uterine cavity, surgical treatment should be considered prior to IVF because of the reduced implantation rate.
