- Brief Summary
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.

- Primary Outcome Measures
Name Time Method Cleavage rate Up to 3 days after insemination The proportion of zygotes that cleave to become embryos on Day 2 (44 ± 1 h post-insemination) .
Clinical pregnancy Up to 30 days after transplantation A pregnancy diagnosed by ultrasonographic examination of at least one fetus with a discernible heartbeat.
Gestational age at birth Up to 42 weeks after transplantation The age of a fetus is calculated by the best obstetric estimate determined by assessments which may include early ultrasound.
Height of offspring 1 year old Up to 1 year after delivery Self-measurement
Miscarriage Up to 42 weeks after transplantation The spontaneous loss of an intrauterine pregnancy.
Birthweight Up to 42 weeks after transplantation Birth weight should be collected within 24 hours of birth and assessed using a calibrated electronic scale with ten-gram resolution.
Weight of offspring 1 year old Up to 1 year after delivery Self-measurement
Implantation rate Up to 30 days after transplantation The number of gestational sacs divided by the total number of embryos transferred, irrespective of whether a pregnancy was established.
Live birth Up to 42 weeks after transplantation The complete expulsion or extraction from a woman of a product of fertilization, after 20 completed weeks of gestational age.
- Secondary Outcome Measures
Name Time Method 1PN rate Up to 2 days after insemination The proportion of inseminated oocytes with one pronucleus on Day 1 (17 ± 1 h post-insemination).
Proportion of good blastocysts Up to 7 days after insemination The proportion of blastocysts with a grade of "good" or higher.
Gestational diabetes Up to 30 weeks after transplantation By oral glucose tolerance test between 24 and 28 gestational weeks (fasting glucose ≥5.1 mmol/L, 1-h glucose ≥10.0 mmol/L, 2-h glucose ≥8.5 mmol/L; one abnormal result sufficient).
Major congenital anomaly Up to 42 weeks after transplantation Structural, functional, and genetic anomalies, that occur during pregnancy, and identified antenatally, at birth, or later in life, and require surgical repair of a defect, or are visually evident, or are life-threatening, or cause death.
Blastocyst development rate Up to 7 days after insemination The proportion of blastocysts observed at 116 ± 2 h post-insemination as a function of the number of normally fertilized oocytes.
Gestational hypertension Up to 42 weeks after transplantation Maternal systolic blood pressure ≥ 140 mmHg and (or) diastolic pressure ≥ 90 mmHg.
Embryo development rate Up to 3 days after insemination The proportion of cleaved embryos at the 4-cell stage on Day 2 (44 ± 1 h post-insemination) or at the 8-cell stage on Day 3 (68 ± 1 h post-insemination) per normally fertilized oocyte.
Ectopic pregnancy Up to 30 days after transplantation A pregnancy outside the uterine cavity, diagnosed by ultrasound, surgical visualization, or histopathology.
Neonatal mortality Up to 30 days after delivery Death of a live born baby within 28 days of birth.
