Filter by:Human Assisted Reproductive Technology (ART) has become a very effective and nearly irreplaceable clinical treatment for infertility, helping millions of women achieve fertility. However, ART may still have potential health risks to mothers and offspring. To better research and monitor the efficacy and safety of ART, the investigators established CXARDR based on the real medical data in Reproductive and Genetic Hospital of CITIC-Xiangya, which is the world's largest ART single treatment center. CXARDR covers the ART full-cycle treatment records since the hospital perfected its electronic medical record system in 2016, as well as biological samples from the CITIC-Xiangya Genetic Resource Bank. From the preoperative investigation of ART to the 1-year follow-up of ART offspring, CXARDR provides the details of the whole process of treatment and the follow-up outcomes of ART patients, making up for the gap in the data of reproductive and obstetric institutions. The huge biological samples with clinical information also provide more possibilities for in-depth basic researches in the field of reproduction and genetics. During the past five years (January 2016 to November 2020), the CXARDR has accumulated data concerning more than 223,000 ART treatment cycles from 120,000 infertile couples. The CXARDR also links more than 180,000 blood samples, 65,000 follicular fluid samples, 80,000 semen samples, and 31,000 granulosa cell samples from 75,000 couples. The data volume is substantial with over 800 variables being documented, and most variables are designed as structured fields. The whole process of data access, data extraction, data processing and data analysis was conducted through a dedicated server inside the CITIC-Xiangya Data Center. All investigators cannot access sensitive information, are required to sign data confidentiality agreement, and need to be approved by the CITIC-Xiangya Ethics Committee.
In assisted reproductive technology, adenomyosis patients are characterized by lower clinical pregnancy rate, lower implantation rate and higher abortion rate. The purpose of this study is to explore whether low molecular weight heparin can reduce the abortion rate of adenomyosis patients in frozen thawed embryo transfer cycles.
This observational study aims the potential role of serum progesterone levels on the day of oocyte pick-up on the probability of pregnancy, in patients undergoing antagonist IVF cycles. There has been evidence, that increased serum levels of progesterone on triggering day are associated with a decreased probability of pregnancy after IVF. There is no study that investigate assocation between serum progesterone levels on the day of oocyte pick-up and IVF outcomes. This study will be the first in this case.
