Where there is no distortion of the endo-myometrial junction, the effect of an intramural leiomyoma on reproductive performance is controversial. The current study compared the performance of patients having a single leiomyoma and intact endometrium confirmed by hysteroscopy (Study group) with that of controls having intact endometrium alone in intracytoplasmic sperm injection (ICSI) cycles. A total of 61 consecutive infertile patients were retrospectively enrolled into the study group from a computerized IVF database. The control group consisted of 444 age-matched patients undergoing ICSI-embryo transfer without any endocervical or intrauterine pathology confirmed by both transvaginal ultrasonography and office hysteroscopy. The baseline characteristics, performance of ovarian stimulation and embryological data were similar between the two groups. The clinical pregnancy per embryo transfer (36 versus 38%) and implantation rate (20 versus 19%) were also comparable. Although the miscarriage rate tended to be higher in the leiomyoma group (27 versus 19%), the difference did not reach statistical significance. In conclusion, in the presence of intact endometrium, a single intramural leiomyoma does not seem to have a deleterious effect on ICSI cycles. Before ICSI is attempted, hysteroscopy may be useful for ruling out distortion of the endometrium due to leiomyoma in selected cases.
