Abstract
Background: Assisted Reproductive Technology (ART) represents a critical advancement in the treatment of infertility, providing hope to many couples struggling to conceive naturally. Despite its success, pregnancy failure remains a significant concern, influenced by various factors such as age, BMI, and underlying medical conditions.
Objective: The main objective of this study was to identify the risk factors associated with pregnancy failure in infertile patients undergoing ART treatments.
Methods: This clinical audit was conducted at Bahria International Hospital, Rawalpindi, from January 2023 to January 2024. Data were collected from 85 patients undergoing ART treatments, including In Vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI). The study included comprehensive demographic information, clinical history, ART cycle details, laboratory results, and lifestyle factors. Pregnancy failure was defined as either biochemical pregnancy loss or clinical pregnancy loss. Ethical approval was obtained, and data were analyzed using SPSS version 25. Descriptive statistics summarized patient characteristics, while comparative analysis and multivariate logistic regression were used to identify significant risk factors.
Results: The study included 85 patients with a mean age of 34.5 years. Those experiencing pregnancy failure had a higher mean age of 36.2 years compared to 33.2 years in those without pregnancy failure. The mean BMI was higher in the pregnancy failure group (26.0 kg/m²) versus the no pregnancy failure group (23.8 kg/m²). Significant risk factors for pregnancy failure included older age (OR=1.15, 95% CI 1.05-1.25, p=0.002), higher BMI (>25 kg/m²) (OR=2.45, 95% CI 1.10-5.47, p=0.03), and the presence of underlying medical conditions (OR=1.90, 95% CI 1.02-3.55, p=0.04).
Conclusion: Older age, higher BMI, and underlying medical conditions significantly increased the risk of pregnancy failure in infertile patients undergoing ART. Personalized treatment approaches addressing these risk factors could improve ART outcomes and enhance the chances of successful pregnancies.
