Abstract
OBJECTIVE
To investigate the effect of luteal phase ovarian stimulation on embryo quality after failed in vitro fertilization-embryo transfer with long or ultra-long protocol.
METHODS
In patients who underwent luteal phase ovarian stimulation after failed in vitro fertilization-embryo transfer with long or ultra-long protocol in the reproductive center between January 2015 and October 2017, self-control observations and statistical analyses were carried out for the number of oocytes retrieved, the rate of fertilization, the rate of D3 high-quality embryos, the rate of transplantable blastocyst formation, and the pregnancy rate of transfer cycle between long or ultra-long protocol and luteal phase ovarian stimulation.
RESULTS
The rate of fertilization and blastocyst were significantly increased after luteal phase ovarian stimulation (P < 0.05). However, the difference of the number of oocytes retrieved and the rate of D3 high-quality embryos was not statistically significant (p > 0.05).
CONCLUSIONS
The patients who failed with long protocol or ultra-long protocol due to low quality embryos, the protocol changed over to luteal phase ovarian stimulation. Can significantly improve the rate of fertilization oocytes and the transplantable blastocyst, and improve the outcome of clinical pregnancy. It provides an alternative ovarian stimulation protocol in patients with IVF-ET failure.
