Frozen Embryo Transfer Clinical Trial
Official title:
3D Power Doppler Ultrasound Assessment of Endometrial and Sub-endometrial Vascularity Before and After PRP Infusion in Frozen-thawed Embryo Transfer Cycles: a Pilot Study.
A good quality embryo and receptive endometrium are important aspects in achieving optimal
outcomes in assisted reproductive treatment (ART). Endometrial thickness is an important
marker of uterine receptivity. A thin endometrium defined by an endometrial thickness ≤7mm
was reported as a poor factor associated with significantly lower implantation and pregnancy
rates as well as a higher risk of miscarriage.
Nowadays, platelet-rich plasma (PRP) intrauterine infusion is a promising approach for the
treatment of refractory thin endometrium in patients undergoing frozen-thawed embryo
transfer. This is based on its ability to stimulate proliferation and angiogenesis with a
large number of growth factors and cytokines i.e. the endometrium becomes thicker, with
higher vascularity. PRP is easily prepared from an autologous blood sample that eliminates
the risk of immunological reactions and transmission infections at low cost.
Endometrial blood flow is another important marker reflective of uterine receptivity.
Although publications are increasing concerning the efficacy of PRP intrauterine infusion on
endometrial expansion and proliferation in frozen-thawed embryo transfer cycles, yet its
angiogenetic effects have not been evaluated so far in either thin endometrium or normal
endometrium thickness.
Our study aims to evaluate endometrial and sub-endometrial vasculature patterns before and
after PRP infusion in frozen-thawed embryo transfer cycles with normal endometrium thickness.
