ABSTRACT

Objectives: To compare the results and to identify the predictive factors for artificial insemination when it is performed after or before 40 hours post-ovulation’s induction.
Patients and methods: A retrospective, comparative study included 202 inseminations performed from March 2007 to April 2010, including all patients who had a complete medical chart from the assisted reproduction center of Saltillo, Coahuila. Group 1 included all patients who were inseminated beyond 40 hours to the administration of hCG and group 2, all patients inseminated before 40 hours, making a crossed analysis of the different variables in each group using square chi and the exact test of Fisher, the statistic software SPSS version 19 was used for the statistic analysis.
Results: 202 inseminations were done: group 1 included 111 inseminations (54.9%) and group 2, 91 inseminations (49.1%), with an overall pregnancy incidence of 18.3% (n = 37), of which 62.1% (n = 23) was from group 1 vs 37.9% (n = 14) of group 2. As predictive factors it was observed that 64.9% with a positive IPT and 75.3% of group 1 vs 20.8% of group 2 presented a follicular rupture in the ultrasound control previous to the insemination. Fluid in posterior fornix was observed in 67.6% (n = 25) of all inseminations with positive IPT.
Conclusions: There were observed better results in percentage of positive IPT and positive predictive factors in group 1.
