Introduction: Medically Assisted procreation (MAP) does not guarantee the outcome of an attempt to conceive. Our goal was to study the factors that can predict the occurrence of pregnancy in stimulated women in our center. Methodology: This was a cross-sectional and retrospective study carried out from August 1, 2016 to January 31, 2018 at the YGESHRTH, comparing two groups of women under the age of 40 years, who had undergone ovarian stimulation during MAP. The first group (group I) consisted of women who had conceived following stimulation during MAP, and group II consisted of those who never conceived. Sampling was consecutive and exhaustive. Discontinuous variables were compared using the Khi-2 test and continuous variables using Student's t-test. A P-value of <0.05 was considered statistically significant. Results: Of the 263 women recruited for the study, 69 (26.2%) had a positive pregnancy test confirmed both by blood samples and ultrasound. The average age of the patients was 33 ± 4.4 years. A significant association was found between the age group of 25-30 years (p = 0.043), a height range of 1.70 - 1.80m (p = 0.001), the transfer of 03 embryos (p = 0.027), the ease of transfer of the embryos (p = 0.030) and the occurrence of pregnancy.
