Embryo glue對一般IVF胚胎植入無明顯助益
但對於不明原因植入仍無法著床之病患可能有所助益
Role of Embryo Glue as a transfer medium in the outcome of fresh non-donor in-vitro fertilization cycles.
Abstract
BACKGROUND:
EmbryoGlue is a hyaluronan-enriched embryo transfer (ET) medium which aids in implantation of embryos, hence, improves pregnancy rates in in-vitro fertilization-ET cycles (IVF-ET).
AIM:
To evaluate the role of EmbryoGlue in improving implantation and pregnancy rates.
DESIGN AND SETTING:
A prospective case-control study conducted at assisted reproductive center of a tertiary care hospital.
METHOD:
In 42 women undergoing IVF, embryos were transferred into 50 μL of EmbryoGlue for 10 min prior to transfer inside uterine cavity. In the control group (n = 42), embryos were transferred to conventional blastocyst culture medium. Statistical analysis was performed using SPSS IBM version 19.0.
RESULTS:
Clinical pregnancy rate in the study group was 7% higher than the control group. The difference, however, was not statistically significant. In addition, no improvement in implantation rates was observed in the study group. However, significant difference (P = 0.04) in clinical pregnancy rate was observed with the EmbryoGlue in patients with previous IVF failure. In the study group, 50% patients (6/12) with previous IVF failure had successful implantation, but in the control group none of the patients (0/11) with previous implantation failure could achieve pregnancy.
CONCLUSION:
It is difficult to conclude a favourable role of EmbryoGlue in IVF-ET cycles with a good prognosis. However, in patients with recurrent implantation failure, it may be considered as a useful transfer medium.
