Abstract

Objective: To assess the outcomes of Day 5 embryo transfer in patients undergoing in vitro fertilization (IVF) at the Reproductive Support Department, A Thai Nguyen Hospital. Subject and method: Retrospective cross-sectional descriptive method of 376 infertility patients who underwent in vitro fertilization at the Reproductive Support Department - A Thai Nguyen Hospital from January 2024 to December 2024. Result: The average age of the wives was 31.55 ± 4.86 years, with 75% of the patients being under 35 years of age. The average duration of infertility was 4.37 ± 3.30 years, with the majority having infertility for less than 5 years. The rates of positive βhCG, clinical pregnancy, biochemical pregnancy, and miscarriage were 57.7%, 42%, 9.3% and 4.3%, respectively. There was no significant difference in the quality of grade 1 and 2 embryos between the two age groups (< 35 and ≥ 35 years). A statistically significant correlation was found between the wife’s age and clinical pregnancy status. No statistically significant difference in the clinical pregnancy rate was observed according to the causes of infertility. Conclusion: Among 376 cases of day-5 embryo transfer, the rates of positive β-hCG, clinical pregnancy, biochemical pregnancy, and miscarriage were 57.7%, 42%, 9.3%, and 4.3%, respectively. There was no significant difference in the quality of grade 1 and 2 embryos between the two age groups (< 35 and ≥ 35 years). The clinical pregnancy rate was higher in women under 35 years of age. Maternal age was one of the factors influencing the outcome of day-5 embryo transfer. No association was found between the causes of infertility and the outcome of day-5 embryo transfer.
