LncRNA NEAT1 affects endometrial receptivity by regulating HOXA10 promoter activity.

fertilization and embryo transfer (IVF-ET) is one of the effective methods to treat female infertility. Poor endometrial receptivity (ER) is an important factor leading to embryo implantation dysfunction, which can reduce pregnancy rate of IVF-ET. The mice model with embryo implantation dysfunction and attachment model of trophoblast (JAR) spheroids were constructed.

Comparison of Cumulative Live Birth Rates Between GnRH-A and PPOS in Low-Prognosis Patients According to POSEIDON Criteria: A Cohort Study.

Objective: To compare the cumulative live birth rate (CLBR) of a gonadotropin-releasing hormone (GnRH) antagonist regimen and a progestin-primed ovarian stimulation (PPOS) regimen in low-prognosis patients according to POSEIDON criteria.

Design: Single-center, retrospective, observational study.

Setting: Henan Provincial People's Hospital, Zhengzhou, China.

The effect of endometrial thickness on pregnancy outcomes of frozen-thawed embryo transfer cycles which underwent hormone replacement therapy.

Objective: To investigate the impact of endometrial thickness on the embryo transfer(ET) day on the clinical pregnancy outcomes of frozen-thawed embryo transfer cycles which have undergone hormone replacement therapy(HRT-FET).

Methods: A total of 10,165 HRT-FET cycles performed between January 2013 to December 2017 in the Reproductive Medicine Center of Henan Provincial People's Hospital were studied retrospectively. All patients were grouped according to their endometrial thickness on the ET day (each group having an increment of 1mm between two neighboring groups).

Analysis of endometrial thickness threshold and optimal thickness interval in cleavage embryo hormone replacement freeze-thawed embryo transfer (HRT-FET).

To investigate the effect of endometrial thickness on the clinical outcome of cleavage embryo HRT-FET on the day of embryo transfer and analyzed the threshold and optimal thickness interval corresponding to ideal clinical pregnancy rate by statistical method. A total of 5861 HRT-FET cycles with cleavage embryo transferred from January 2013 to December 2017 in the Reproductive Medicine Center of Henan Provincial People's Hospital were studied retrospectively．Fifth-order grouping of endometrial thickness (EMT) on embryo transfer day as a continuous variable by statistical software, they were divided into five subgroups: Q1 (EMT:4.0-7.
