Infectious complications of intrauterine insemination: a case report and literature review.

Intrauterine insemination is commonly performed in the treatment of infertility. Infectious complications associated with intrauterine insemination are frequently cited, though rarely reported. A review of the literature yields only five reported cases of pelvic infections subsequent to intrauterine insemination (IUI), and only two of these show firm evidence of infection, with none presenting bacteriologic confirmation. We report a case of Escherichia coli septicemia subsequent to an IUI performed on a patient with a large adenomyoma. Of 147 patients treated with IUI at Georgetown University from November 1987 through March 1990, this was the only infectious complication. The incidence of infectious complications in our series is thus 0.0068 (6.8 per 1,000 women). A review of infectious complications in 38 reported series on intrauterine inseminations reveals five infections in 3,129 patients. With the addition of our series to the literature, the prevalence of infectious complications is 1.83 per 1,000 women undergoing IUI. The rates were not significantly altered by semen washing with antibiotics, or the administration of prophylactic antibiotics to the woman (P = .81). We conclude that (1) the infection rate following IUI is small, (2) many of the infections subsequent to insemination were not associated with intrauterine insemination, (3) most reported cases of infection fail to show evidence for the actual presence of infection, and (4) the prevalence is unaltered by the administration of prophylactic antibiotics or washing the semen sample with antibiotics.
