Clinical Report: Investigation of Transfer-Day Variables Influencing Clinical Pregnancy Outcomes Following ICSI
Overview
This study investigates the impact of female age, AMH levels, sperm origin, and transfer timing on clinical pregnancy outcomes after ICSI. Key findings indicate that older maternal age and invasive sperm sources are associated with lower pregnancy odds, while higher AMH levels and blastocyst transfers correlate with improved outcomes.
Background
Understanding the factors influencing clinical pregnancy outcomes in assisted reproductive technology is crucial for optimizing patient counseling and treatment strategies. Female age is a well-established predictor of success in IVF and ICSI, but other variables such as AMH levels and sperm source may also play significant roles. This study aims to refine transfer-day counseling by focusing on these specific variables.

Key Findings
Clinical pregnancy occurred in 12.3% of transfers (37 of 300).
Older maternal age is associated with lower odds of clinical pregnancy (aOR 0.91 per year).
Higher AMH levels correlate with increased odds of clinical pregnancy (aOR 2.02 per unit).
Invasive sperm sources are linked to decreased odds of pregnancy (aOR 0.39).
Blastocyst transfers yield higher odds of clinical pregnancy compared to cleavage-stage transfers (aOR 3.90).
Clinical Implications
Clinicians should consider female age, AMH levels, sperm source, and transfer stage when counseling patients about the likelihood of clinical pregnancy following ICSI. These factors can provide a more nuanced understanding of transfer outcomes, aiding in informed decision-making.
Conclusion
The study highlights important associations between transfer-day variables and clinical pregnancy outcomes, suggesting that these factors should be integrated into patient counseling. However, further validation in larger studies is necessary before routine implementation.
