Filter by:It has been described that 11% of men with semen values within the normal range established by the World Health Organization (WHO) have sperm DNA fragmentation. This has been associated with a lower fertilization rate, lower embryo development and, therefore, lower reproductive success. Focusing on the study of the integrity of the male genome can provide us information to diagnose infertility in the couple. The use of conventional sperm selection methods such as swim-up or density gradients has been a great advance in the improvement of male fertility. However, these methods use centrifugation in their protocol, a procedure that has been associated with sperm DNA damage. The ZyMōt is a chip based on microfluidic properties that allows the recovery of spermatozoa with lower DNA fragmentation rate without centrifugation of the semen sample. This new sperm selection method maintains all the advantages of conventional techniques, but decreasing DNA fragmentation associates to sperm recoveries techniques eventually improving reproductive rates. This quality would be beneficial for patients with unexplained infertility, recurrent pregnancy loss or clinical varicocele, factors that have been associated with a higher index of DNA fragmentation. However up to date there is evidence-based data supporting such improvement. The main objective of the present project is to evaluate the ZyMōt as a new non-invasive sperm selection device and to see its impact on the euploidy rate, comparing it with a sperm selection technique that is routinely used in the clinic: swim-up. At the same time, the effect that this new chip may have on sperm and other reproductive variables will be analyzed clinically, and molecularly with immunohistochemical and transcriptomic analyses in order to observe the impact of SDF at the molecular and genomic level in oocytes with low reparative potential oocytes.
The purpose of this clinical trial is to see if intrauterine growth hormone infusions can help subjects reach a suitable endometrial thickness in patients who are resistant to routine hormonal therapy for embryo transfer in the In Vitro Fertilization (IVF) cycle. The primary aim of this study is to assess the effectiveness of injecting Growth hormone directly into the uterus to enhance endometrial thickness. Additionally, we aim to compare the likelihood of pregnancy between patients receiving the Growth hormone infusion and those receiving a placebo.
This study aims to assess the clinical significance of cleavage stage (Day 3) assisted hatching compared to assisted hatching at the blastocyst stage (Day 5,6,7) of embryo development at the time of trophectoderm (TE) biopsy for patients undergoing in vitro fertilization (IVF) and preimplantation genetic testing for aneuploidy (PGT-A) for treatment of their infertility.
The goal of this clinical trial is to learn if partial meniscal replacement can prevent or postpone total meniscal replacement, in adult patients (female/male) with partial meniscal loss. The main questions it aims to answer are: - Can partial meniscal replacement improve knee function? - Can partial meniscal replacement prevent/postpone total meniscal replacement/knee prothesis? Researchers will compare the results of the operated group with patients not willing to be operated but with partial meniscal loss to see if the operation improves knee function. Participants will be operated and have to attend follow-up visits with MRI after 6 months up to 5 years after surgery.
A Phase 3 clinical trial of oral GnRH antagonist pre-treatment for women with endometriosis who are undergoing IVF, with a primary outcome of live birth rate. The investigators' central hypothesis is that in infertile woman with endometriosis undergoing in vitro fertilization-embryo transfer (IVF-ET), live birth rates will improve in those pretreated with GnRH antagonist compared to those not pretreated with GnRH antagonist.
This is a retrospective review of treatment outcomes from fertility clinics in The Prelude Network who have used Igenomix for PGT-A and have transferred embryos with initial chaotic results, regardless if re-biopsy was performed.
The investigators conduct a long-term follow-up at five years on offspring born from our randomized controlled trial (RCT) to investigate whether or not there is any difference in developmental outcomes in children born after capacitation IVM (CAPA IVM) compared with conventional IVF in order to give strong evidence about the safety of IVM in women with high antral follicle count.
Retrospective observational study comparing information received on Inception Central Donor Recruitment's standardized online egg donor application compared to information reported during a genetic risk assessment consultation with a certified genetic counselor with contracted third party genetic counseling service, GeneScreen. All donor applicants completing a full application with Inception's Central Donor Recruitment and a GRA consultation with GeneScreen will be included.
To explore whether there is a significant difference in the cumulative live birth rate and maternal and child health outcomes between cancer patients who undergo or do not undergo fertility preservation before receiving anti-tumor treatment and non-cancer patients who undergo assisted reproductive technology treatment/natural pregnancy. This study will be conducted in the Clinical Center of Reproductive Medicine, First Affiliated Hospital of Nanjing Medical University. 2800 women diagnosed with malignant cancers who has desire to reproduce will be enrolled in this study. Statistical analysis of the data will be performed.
Non-obstructive azoospermia (NOA) stands as the most severe form of male infertility. However, due to the diverse nature of testis focal spermatogenesis in NOA patients, accurately assessing the sperm retrieval rate (SRR) becomes challenging. The current study aims to develop and validate a noninvasive evaluation system based on machine learning, which can effectively estimate the SRR for NOA patients. In single-center investigation, NOA patients who underwent microdissection testicular sperm extraction (micro-TESE) were enrolled: (1) 2,438 patients from January 2016 to December 2022, and (2) 174 patients from January 2023 to May 2023 (as an additional validation cohort). The clinical features of participants were used to train, test and validate the machine learning models. Various evaluation metrics including area under the ROC (AUC), accuracy, etc. were used to evaluate the predictive performance of 8 machine learning models.
