Objective:
To evaluate the combined effect of endometrial thickness and anatomic uterine factors on clinical outcome in oocyte donation recipients.
Design:
Retrospective analysis of oocyte donation cycles conducted between 2005 and 2010.
Setting:
Two private IVF centers.
Patient(S):
A total of 737 donor oocyte cycles.
Intervention(S):
None.
Main Outcome Measure(S):
Clinical pregnancy and live birth rates.
Result(S):
No statistically significant difference was found in clinical pregnancy rates and live birth rates in cycles with endometrial thickness <6 mm compared with those with endometrial thickness >10 mm. However, a relatively high rate of live births was found within a medium range of endometrial thickness (8.2-10 mm). All intrauterine adhesion cases occurred in cycles with thinner endometrium.
Conclusion(S):
No statistically significant difference was found in clinical pregnancy rates and live birth rates in cycles with endometrial thickness <6 mm compared with those with thickness >6 mm. A relatively high rate of live births was found within a medium range of endometrial thickness (9.1-10 mm).
