Prognostic Factors to Achieve Pregnancy with Artificial Intrauterine Inseminations

Abstract

Introduction: Artificial insemination consists of depositing sperm in the female genital duct in order to achieve pregnancies.
Objective: To evaluate prognostic factors of success for pregnancy and calculate the rate accumulated by cycles of intrauterine insemination.
Method: A descriptive, prospective, analytical and longitudinal study was carried out in cycles ran between 2014 and 2016. Infertile women aging 24 and 41 years were included. We determined type and time of infertility, causes, sperm density and mobility post-capacitation, number of follicles, endometrial thickness, and number of cycles in which insemination was performed. Ultrasound follicular follow-up and controlled ovarian stimulation, according to established protocols, were performed. The results were analyzed using the SPSS 15.0 program. The categories were evaluated in frequencies and percentages.
Results: Two hundred ninety (290) couples were studied with 736 total cycles. The pregnancy rate per cycle and in pairs was 8.3 and 21.0% respectively, ages ranges 33.3 ± 5.2 years. The three significant variables were time of infertility, sperm motility and number of the cycle in which insemination was performed.
Conclusions: The greatest success is achieved in the first two treatment cycles, in couples with less than four years of infertility and sperm motility ≥ 77.6%.
