Cycle-to-cycle variation in utero-ovarian hemodynamic indices in ovarian stimulation and natural cycles of the same women and its effect on the outcome of assisted reproduction treatment

Influence of endometrial thickness on pregnancy rates in modified natural cycle frozen‐thawed embryo transfer

“…Consistent with previous reports, embryo quality was confirmed in the present study to be the key independent predictor for ongoing pregnancy. Veleva et al showed that transfer of a high quality embryo resulted in higher pregnancy and live birth rates, and comparable results were obtained by others . However, none of these studies included endometrial thickness in their analyses.…”

“…Despite the observed trend towards lower pregnancy rates in woman with an endometrial thickness <7 mm, caution is necessary because the number of patients in the subgroup analyses was limited. A small retrospective study containing 62 patients undergoing true NC‐FET showed a comparable negative effect of an endometrial thickness <7 mm . So, even while an endometrial thickness of 7 mm is considered by many to be the minimal endometrial thickness required before proceeding to thawing and transferring, a robust foundation for this assumption is missing .…”

Comparison of 2-Dimensional, 3-Dimensional, and Vascular Ultrasonographic Parameters for Endometrial Receptivity Between 2 Consecutive Stimulated In Vitro Fertilization Cycles

“…Little information was available in the literature with regard to the comparison of ultrasonographic parameters in the same patients. [23][24][25] We evaluated ultrasonographic parameters between stimulated and natural cycles in the same patients. 8 The endometrial thickness and volume were significantly higher in stimulated cycles than in natural cycles, whereas endometrial and subendometrial 3D power Doppler indices were significantly lower in stimulated cycles.…”

Utero-ovarian hemodynamics after laparoscopic treatment of infertility caused by moderate to severe endometriosis

“…Slična merenja su vršena u mnogobrojnim studijama kao procena za adekvatnost primene IVF-a, pogotovu kod prisutne endometrioze. (1,15,18,33,53,152 ).…”

“…Basir et al su pronašli da u IVF ciklusima stopa graviditeta signifikantno opada sa kada su uterusni pulsatilni indeks veći od 2.7 a indeks rezistencije veći od 0.9, što je potvrĎeno i u ovoj studiji. (14,15,78,79,82).…”
