Association between uterine volume and pregnancy outcomes in adenomyosis patients undergoing frozen-thawed embryo transfer

Research questionWhat is the relationship between uterine volume before frozen-thawed embryo transfer (FET) and reproductive outcomes among adenomyosis patients?DesignClinical characteristics and outcomes of adenomyosis patients undergoing IVF and FET in a tertiary academic hospital were retrospectively analysed. Only first blastocyst transfer cycles were included. The main outcome measures included clinical pregnancy rate (CPR), miscarriage rate and live birth rate (LBR).ResultsA total of 158 adenomyosis patients were enrolled. Receiver operating characteristic (ROC) curve analysis indicated that uterine volume before FET was negatively related to LBR, with area under the curve of 0.622 (95% confidence interval [CI] = 0.531–0.712, P = 0.012). The cut-off value for the curve was 98.81 cm³. Grouped by the cut-off of uterine volume, 83 women were included in group A (≤98.81 cm³) and 75 in group B (>98.81 cm³). No significant difference was found in CPR between two groups. Compared with group A, the incidence of miscarriage in group B was significantly increased (51.28% versus 16.28%, P = 0.001). LBR in group B was markedly lower than in group A (25.33% versus 43.37%, P = 0.020). Logistic regression analysis revealed that, after adjusting for potential confounders, uterine volume before FET was not associated with CPR (odds ratio [OR] 1.149, 95% CI 0.577–2.286, P = 0.693) but was positively related to miscarriage rate (OR 8.509, 95% CI 2.290–2.575, P = 0.001).ConclusionsAdenomyosis patients with larger uterine volume (>98.81 cm³) before FET might have a lower LBR due to higher incidence of miscarriage. Reduction of uterine volume before embarking on FET procedures should be recommended.     

Endometrial thickness significantly affects clinical pregnancy and live birth rates in frozen-thawed embryo transfer cycles

In order to explore the relationship between endometrial thickness on the day of embryo transfer and pregnancy outcomes in frozen-thawed embryo transfer (FET) cycles, we retrospectively analyzed data from 2997 patients undergoing their first FET cycles from January 2010 to December 2012. All patients were divided into three groups (Group A, ≤8?mm; Group B, 9–13?mm; Group C, ≥14?mm) according to the endometrial thickness on embryo transfer day. Compared with patients in the other two groups, patients with thin endometrial thickness in Group A had significantly lower clinical pregnancy rate (33.4%, 41.3% and 45.4%, p?p?p?p?相似文献   

Effect of transdermal estrogen dose regimen for endometrial preparation of frozen-thawed embryo transfer on reproductive and obstetric outcomes

PurposePrevious studies have reported different methods of estrogen administration during endometrial preparation for frozen‐thawed embryo transfer (FET). This study aimed to investigate a beneficial regimen of transdermal estrogen administration for FET.MethodsWe investigated the reproductive and obstetric outcomes of FET by comparing the increasing dose (ID) group that mimics changes in serum estradiol during the menstrual cycle and the constant dose (CD) group. Transdermal patches were used for estrogen administration in both groups. In our hospital, we targeted 315 cycles of the ID group in which FET was performed in 2017 and 324 cycles of the CD group in which FET was performed in 2018. In all cases, single embryo transfer was performed.ResultsAll were singleton pregnancies. There was no difference in clinical pregnancy rate (28.9% vs 28.2%, P =.837) and live birth rate (17.3% vs 21.4%, P =.201) between the ID and CD groups. Spontaneous abortion rate was significantly lower in the CD group than in the ID group (37.2% vs 23.0%, P =.041). There was no difference in obstetrical outcomes.ConclusionsIt was considered that the simple CD regimen may be more beneficial than the complicated ID regimen.

Influence of endometrial thickness and pattern on pregnancy rates inin vitro fertilization-embryo transfer

Aim : Our aim was to investigate the role of endometrial thickness and pattern in the pregnancy rate during an in vitro fertilization-embryo transfer (IVF-ET) cycle.
Methods : Records of patients who underwent IVF-ET at the Jichi Medical School Hospital during May 1995–December 1999 were evaluated retrospectively. Only cycles, in which endometrial thickness and pattern on the day of human chorionic gonadotrophin (HCG) administration were recorded, were analyzed in this study. Endometrial thickness was divided into three categories (A: < 10 mm, B: 10–14 mm, C: > 14 mm), and endometrial pattern was divided into two categories: triple line and non-triple line. A total of 156 IVF-ET cycles from 120 patients was evaluated.
Results : There were no significant differences for both the endometrial thickness and pattern in the pregnancy rate during the IVF-ET cycle ( P  > 0.05). Among the study groups, the triple-line endometrial pattern was found to be 58.7% in group A, 84.0% in group B and 70% in group C. We found that in the triple-line endometrial pattern, there was a significant difference between group A and group B ( P  < 0.01). Triple-line endometrial pattern appeared significantly in younger women (33 ± 5.4 years) than in non-triple-line endometrial pattern (36 ± 5.2 years; P  = 0.047). The minimum and maximum endometrial thickness where pregnancy occurred was 6.5 mm (two pregnancies) and 19 mm (one pregnancy), respectively.
Conclusion : Endometrial thickness and pattern have no influence on the pregnancy rates in an IVF-ET cycle, but patients with triple-line endometrial pattern and group B endometrial thickness showed a better pregnancy outcome in the IVF-ET treatment. (Reprod Med Biol 2002; 1 : 17–21)     

Modified hMG stimulated: an effective option in endometrial preparation for frozen-thawed embryo transfer in patients with normal menstrual cycles

To evaluate the clinical efficacy of modified human menopausal gonadotropin (hMG) stimulated, hormone replacement therapy (HRT), natural cycling and letrozole ovulation induction during endometrial preparation for frozen-thawed embryo transfer (FET) in patients with normal menstrual cycles. This retrospective analysis included a total of 5070 cycles of patients with normal menstrual patterns who underwent FET between October 2009 and September 2015. The patients were divided into four groups according to the method of endometrial preparation for FET: 1838 cycles were natural, 1666 underwent HRT, 340 underwent letrozole ovulation induction and 1226 underwent modified hMG stimulated. Reproduction-related clinical outcomes in the four groups were compared. The clinical pregnancy rates and live birth rates of patients in the modified hMG stimulated group were significantly higher than that in the other groups p?p?>.05). Modified hMG stimulated resulted in a higher pregnancy rate compared to the other treatment groups. Therefore, modified hMG stimulated may be an effective option in endometrial preparation for FET in patients with normal menstrual cycles.
