Introduction: The analysis of a cohort of patients during the embryo transfer phase was the main focus of this study. The aim of the study was to examine the effects of thirteen adjuvant therapies on the success of embryo transfer, including the clinical pregnancy and live birth rates with enoxaparin. Materials and Method: A random number was applied to each transfer in order to ensure data independence, and it was then used to select a single transfer for each patient while erasing the other 90 duplicate cycles. Gonadotropin stimulation was either downregulated or gonadotrophin antagonist stimulation—with or without pre-treatment with the oral contraceptive pill—was used to stimulate. Vitrification was used to freeze the embryos. Results: 16 known seropositive IVF implantation failure patients had 25 additional transfers of 47 embryos, resulting in two clinical pregnancies (fetal heart implantation rate, 42%). These patients did not want to participate in the trial and did not receive heparin and aspirin from their treating physician. Conclusion: A large number of the interventions examined in this study fall short of demonstrating any effects on the success of embryo transfers. According to the findings of our analysis enoxaparin use has shown promising, possibly advantageous results.
