Effect of luteinized unruptured follicle cycles on clinical outcomes of frozen thawed embryo transfer in Chinese women.
OBJECTIVE
To determine the effect of luteinized unruptured follicle (LUF) cycles on frozen thawed embryo transfer (FET).


METHODS
A retrospective analysis comparing the clinical outcomes after FET among 144 cases of luteinized unruptured follicle (LUF) cycles and 866 cases of ovulation cycles.


METHODS
Reproductive medical center, Beijing China.


METHODS
Chinese infertile women who underwent FET.


METHODS
None.


METHODS
Clinical pregnancy rate (PR), implantation rate.


RESULTS
The implantation rate, clinical pregnancy rate, on-going pregnancy rate and live birth rate in LUF group were 12.76% (49/384), 27.78% (40/144), 24.31% (35/144) and 19.44% (28/144), respectively, and in ovulation group, 14.74% (332/2251), 31.29% (271/866), 28.29% (245/866) and 22.23% (193/866), respectively (p > 0.05).


CONCLUSIONS
LUF does not affect the clinical outcomes of FET. Patients of LUF should be included in FET treatment.
