hCG Concentration in Peripheral Maternal Blood After Embryo Transfer, Ongoing Pregnancy Rates, and Morphokinetics

NCT04744519 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 300

Last updated 2021-02-09

No results posted yet for this study

Summary

hCG is a hormone produced very early by the embryo, but not by the oocyte. It has a pivotal role in the trophoblast differentiation, and embryo implantation as well as the corpus luteum support. In spite of its well-known role, the literature about it is scarce.

The aim of this retrospective study is to evaluate the relationship between the hCG concentration in peripheral maternal blood measured 11 days after embryo transfer, embryo morphokinetics pattern and the abortion and ongoing pregnancy rates.

We will study patients having transference of blastocyst cultured in time lapse monitored incubators and will check all the morphokinetics parameters with the IVI database.

Conditions

  • hCG

Interventions

OTHER

Collect data

\- Controlled ovarian stimulation with GnRH antagonists effected to the patients in order to get their eggs through follicular puncture, which will be trigger by GnRH analogue. The eggs will be isolated and processed according to the standard protocol.
