Summary
Assisted hatching improved pregnancy rates in patients with prior implantation failure. Women aged 35-39 experienced the highest success with this assisted reproductive technology.
Area of Science:
- Reproductive Medicine
- In Vitro Fertilization
- Embryology
Background:
- Assisted hatching (AH) enhances implantation rates in specific patient groups with poor prognosis.
- This study investigates AH's impact on patients with previous implantation failures, stratified by age.
Purpose of the Study:
- To compare pregnancy rates between patients undergoing in vitro fertilization (IVF) with AH after implantation failure and those attempting IVF without AH.
- To analyze these rates across different age demographics.
Main Methods:
- A retrospective study of patients undergoing AH between January 2008 and December 2009.
- Patients were categorized into three age groups: >35 years (Group I), 35-39 years (Group II), and >40 years (Group III).
Main Results:
- Group II (35-39 years) demonstrated the highest pregnancy rate at 30%.
- Patients utilizing AH achieved a 20% pregnancy rate, whereas the control group (no AH) reported no pregnancies.
Conclusions:
- Assisted hatching appears beneficial for patients experiencing implantation failure during IVF.
- The 35-39 age group showed the most promising outcomes with assisted hatching.
