NCT ID: NCT05724979 Completed - Infertility, Male Clinical Trials

Outcome of Using Sperm Bound to the Zona Pellucida of Immature Oocytes for Intracytoplasmic Sperm Injection (ICSI)

Start date: March 5, 2021
Phase: N/A
Study type: Interventional

In vivo, the zona pellucida (ZP) of the oocyte can bind to normally functional sperm. The ZP-sperm interaction is one of the final steps of natural selection during their journey in the female reproductive tract. In the current study, we evaluated the ability of the ZP of immature oocytes to harvest the fittest sperm. We compared the embryological outcomes of intracytoplasmic sperm injection (ICSI) using conventionally selected sperm (control group) and ZP-bound sperm (intervention group). Our results showed no statistically significant superiority for the ZP binding technique over the conventional sperm selection with respect to the rates of fertilization and cleavage. However; the rates of blastocyst formation and high-quality blastocysts were significantly improved in the intervention group compare to the control group. These findings imply that the proposed technique can serve as a cost-effective and natural sperm selection method that has the potential to enhance the embryological and clinical outcomes of intracytoplasmic sperm injection (ICSI).

NCT ID: NCT05578118 Completed - Infertility Clinical Trials

Health of Children Born From ICSI With AOA (AOA-BABIES)

Start date: August 23, 2022
Phase:
Study type: Observational

The investigators follow up on the development of children born from ICSI-AOA using the Developmental Red Flags and Ages & Stages Third Edition (ASQ-3) Questionnaires to give strong evidence about the safety of AOA in assisted reproductive technology.

NCT ID: NCT05567731 Completed - Infertility Clinical Trials

Effect of GnRH Agonist Treatment Protocols on Ovarian Reserve

Start date: October 15, 2022
Phase: N/A
Study type: Interventional

This study aimed to compare the gonadotropin-releasing hormone agonist (ultra-short) protocol versus (short and long) protocols on ovarian reserve in women undergoing intracytoplasmic sperm injection

NCT ID: NCT04727684 Completed - Infertility Clinical Trials

Effect of GnRH Agonist vs GnRH Antagonist on Oocyte Morphology in Polycystic Ovary Syndrome Patients During IVF/ICSI

Start date: August 22, 2020
Phase: Phase 4
Study type: Interventional

Selection of developmentally competent oocytes enhances IVF efficiency. Usually, oocyte quality is determined based on its nuclear maturation and the presence of specific cytoplasmic and extracytoplasmic morphologic features. Gonadotropin-releasing hormone agonists (GnRH Agonists) and gonadotropin-releasing hormone antagonists (GnRH Antagonists) are used during controlled ovarian stimulation (COS) protocols in order to prevent premature luteinizing hormone (LH) surge and premature ovulation. However, GnRH receptors are also expressed in extra-pituitary tissues such as ovary, but it is still unknown whether the type of GnRH analogues used during COS could affect the oocyte morphology in polycystic ovary syndrome (PCOS) patients. The aim of this prospective, non-randomised, open-label, clinical trial is to compare the effects of two pituitary suppression regimens; GnRH Agonist-Long Protocol and GnRH Antagonist-Flexible Protocol on oocyte morphology in PCOS patients during IVF/ICSI.

NCT ID: NCT04727671 Completed - Infertility Clinical Trials

Effect of GnRH Agonist vs GnRH Antagonist on IVF/ICSI Outcomes in Polycystic Ovary Syndrome Patients.

Start date: December 22, 2019
Phase: Phase 4
Study type: Interventional

This prospective, non-randomised, open-label, clinical trial is conducting on polycystic ovary syndrome (PCOS) subjects to compare the effects of two pituitary suppression regimens; GnRH Agonist-Long Protocol and GnRH Antagonist-Flexible Protocol on clinical and embryological IVF/ICSI outcomes, and on the follicular fluid levels of Placental Growth Factor (PlGF); which is known for his pivotal role in the regulation of ovulation, embryo development, and implantation

Effect of GnRH Agonist vs GnRH Antagonist on Oocyte Morphology During IVF/ICSI

Start date: August 22, 2020

Selection of developmentally competent oocytes enhances IVF efficiency.

Gonadotropin-releasing hormone agonists (GnRH Agonists) and gonadotropin-releasing hormone antagonists (GnRH Antagonists) are used during controlled ovarian stimulation (COS) protocols in order to prevent premature luteinizing hormone (LH) surge and premature ovulation. However, GnRH receptors are also expressed in extra-pituitary tissues such as ovary, but it is still unknown whether the type of GnRH analogues used during COS could affect the oocyte morphology, especially with the limited and conflicted currently available data. Thus, we are conducting this prospective, non-randomised, open-label, clinical trial to compare the effects of two pituitary suppression regimens; GnRH Agonist-Long Protocol and GnRH Antagonist-Flexible Protocol on oocyte morphology during IVF/ICSI.
