Immobilization After Intrauterine Insemination May Boost Success
Women immobilized for 15 minutes were found to have increased ongoing pregnancy rates
FRIDAY, Oct. 30 (HealthDay News) -- A brief period of immobilization after intrauterine insemination improves ongoing pregnancy rates, according to a study published online Oct. 29 in BMJ.
Inge M. Custers, M.D., of the Academic Medical Centre in Amsterdam, Netherlands, and colleagues randomized 391 women having intrauterine insemination for unexplained, cervical factor or male subfertility to 15 minutes of immobilization or immediate mobilization after insemination.
The researchers found that the ongoing pregnancy rate per couple was significantly higher in the immobilization group than in the immediate mobilization group (27 versus 18 percent). Ongoing pregnancy rates in the first, second, and third treatment cycles were 10, 10, and 7 percent, respectively, in the immobilization group, and 7, 5, and 5 percent, respectively, in the mobilization group. The live-birth rate was 27 percent in the immobilization group and 17 percent in the mobilization group.
"In treatment with intrauterine insemination, 15 minutes immobilization after insemination is an effective modification. Immobilization for 15 minutes should be offered to all women treated with intrauterine insemination," the researchers conclude.
