Evaluation of uterine cavity by sonohysterography in women scheduled for intracytoplasmic sperm injection

A prospective study was performed to determine the feasibility of evaluatin g the uterine cavity by sonohysterography (SHG) in women who were scheduled for intracytoplasmic sperm injection (ICSI) due to severe male factor infe rtility and who had not had a previous hysterosalpingography (HSG). Sonohys terography was performed in 80 women scheduled for ICSI, A subsequent hyste roscopy was undertaken in patients with intracavitary lesions. The outcome of ICSI for the women undergoing SHG was compared with that of 240 cycles p erformed (during the same time period) in patients who had a normal HSG bef ore admission to the clinic. There were no complications attributable to th e SHG procedure. Hysteroscopy correctly identified all lesions depicted by SHG. SHG and HSG groups were comparable with regard to female age and durat ion of infertility, Clinical pregnancy rates per transfer were 40.2% and 42 .5% in the SHG and HSG groups, respectively. Abortion rates in the two grou ps were also similar (14.8 and 11.0%, respectively). In conclusion, sonohys terography appears to be a simple, inexpensive, and safe alternative to HSG for evaluation of the uterine cavity in women scheduled for ICSI.
