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.
To determine if the mean elasticity value (measured in kilopascals, kPa) of a patient's endometrium, myometrium and cervix in a sonographically normal appearing uterus predict frozen embryo transfer (FET) success and long term reproductive outcomes when measured the day prior to FET.
This is a randomized multi-centre, assessor-blind, parallel-group study to be conducted in 250 women in the age group of 20 to 39 years (both inclusive), who are indicated to undergo COS as part of assisted reproductive technology (ART). The participant will receive r-hFSH, fixed-dose for 5 days, and day 6 onwards the dose may be adjusted for a single cycle of COS followed by ART procedures, and post-ART follow-up for ongoing pregnancy. The primary and secondary outcomes will be captured on days as per protocol. Adverse events will be noted for safety evaluation.
This study evaluates the addition of clomiphene citrate (CC) to letrozole for the treatment of infertility in women with polycystic ovary syndrome across a course of two treatment cycles with stair step dosing of letrozole similar to standard of care. Half of the participants will receive letrozole and CC in combination, while the other half will receive letrozole alone.
Retrospective chart review of data on the use of traditional IVF and INVOcell IVC collected from clinics using both technologies. The retrospective data will be utilized for a comparison of the two methods.
Purpose: To determine the efficacy and safety of daily injections of gonadotropin-releasing hormone agonist in comparison with the standard strategy of supporting the luteal phase in protocols with gonadotropin-releasing hormone antagonists, in patients at risk of developing ovarian hyperstimulation syndrome and changing the trigger to a gonadotropin-releasing hormone agonist. Materials and Methods: This prospective, controlled, randomized study, conducted at the Clinic of the Federal State Budgetary Educational Institution of Higher Education of the KubSMU of the Ministry of Health of Russia, included 102 patients at risk of developing ovarian hyperstimulation syndrome, who were on protocols with gonadotropin-releasing hormone antagonists and changing the ovulation trigger to a gonadotropin-releasing hormone agonist. All patients underwent blastocyst transfer on day 5. Patients of the first group (n = 51) received as support for the luteal phase gonadotropin-releasing hormone agonist daily 0.2 mg, subdermally, patients of the second group (n = 51) progesterone 10 mg 3 times a day, orally and estradiol 1 mg 3 times a day, transdermal. The level of progesterone on the day of transfer, the incidence of clinical pregnancy, and the incidence of ovarian hyperstimulation syndrome in both groups were compared.
Observational, single-center, prospective case-control study, in which each patient is his own control. It focuses on the study of tubal patency and establishing the agreement of results between HyFoSy and HSG.
Singapore's fertility rate is currently below 1.2, raising concerns about population ageing and long-term sustainability. The fertility decline is characterized by falling birth rates among women in their 20s with almost no recuperation among women in their 30s. This project explores a) whether informational imperfections help to account for high intended ages at childbearing in Singapore, b) whether informational interventions significantly affect ideal and expected ages at marriage and childbearing, and expected probability of undergoing social egg freezing, and c) whether informational interventions significantly affect expected and actual educational outcomes and labor market outcomes. Our hypotheses are: 1. University students have knowledge gaps about age-related onset of infertility, assisted reproductive technologies and local policy initiatives related to age at marriage and childbearing, especially among male students. 2. Being exposed to accurate information in these domains leads to significantly lower ideal/expected ages at marriage and childbearing, and higher expected probability of undergoing social egg freezing, immediately after the intervention. 3. Being exposed to accurate information in these domains does not lead to lower educational and labor market expectations immediately after the intervention among either male or female students, or to significant differences in module choices, Cumulative Average Point (CAP), starting salary and employment status of university students in the following academic semester and six months after graduation, among either male or female students.
The aim of the present study is to investigate serum estradiol and progesterone levels in women conceiving after natural, estradiol + progesterone or gonadotropin stimulated frozen embryo transfer (FET) cycles.
A non-inferiority, prospective parallel group, multi-center, randomized controlled trial to investigate whether selection of a single blastocyst for transfer using the deep learning tool, iDA, results in non-inferior clinical pregnancy rate compared to trained embryologists using standard morphology criteria.
