Evaluation of demographic information and consequences of in vitro fertilization in pregnant women in 2019-2020

Background: Assisted reproductive techniques have increased the chances of pregnancy for couples looking for a way to treat their infertility. To increase the effectiveness of these methods, studies are needed to identify the determinants of a successful pregnancy with these techniques. Methods: The present study is a cross-sectional retrospective study that was performed on 253 couples who were referred for infertility treatment to the infertility clinic of Shahid Beheshti Hospital in Isfahan from April 2019 to March 2020 to evaluate the results of pregnancy in vitro fertilization. Demographic, clinical, and laboratory data from patient records were collected and entered into checklists. Results: Out of 253 couples, eighty-five (33.6%) became pregnant by IVF. The mean age of women with successful pregnancies was 33.96±5.2 years and in the unsuccessful pregnancies was 35.84±5.07 years. The results of this study showed that women who had a successful pregnancy after IVF were significantly younger than women who did not have a successful pregnancy (P=0.006). In the classification of patients into two groups of positive and negative pregnancies, younger age, adequate vitamin D levels, and higher sperm motility were the determinants of pregnancy in the first period of fertilization (Fresh protocol). Also, the existence of a failed history of infertility treatment in couples has been introduced as a negative factor for IVF fertility. 13(15.9%) abortions occurred and 11(12.9%) infants who were born with this method needed intensive care. Conclusion: Lower age at the time of fertilization, higher vitamin D levels, and more active sperms were found to have important and prognostic roles in the success of pregnancy by in vitro fertilization technique. The results of the present study showed that, Increased unsuccessful treatment has been associated with the history of failed treatment. Therefore, to respond to the relationship between previous infertility treatments and success in subsequent pregnancies in the IVF process, It is recommended to conduct studies with larger sample size and at a higher time efficiency.
