Not applicable Interventional Merrion Fertility Clinic · NCT06602687

This study is testing if a special sperm selection method called PICSI can improve the quality of embryos for couples trying to conceive through assisted reproductive technology.

What this trial studies

This study investigates the effects of Physiologic Intracytoplasmic Sperm Injection (PICSI) on the euploidy rates of embryos in couples undergoing assisted reproductive technology. By selecting sperm based on their ability to bind to hyaluronic acid, the study aims to improve sperm quality and ultimately enhance embryo viability. Couples with specific age criteria and a minimum number of mature eggs will be included, while those using donor or frozen gametes will be excluded. The study builds on previous findings that suggest PICSI may reduce miscarriage rates, despite mixed results regarding live birth rates.

Who should consider this trial

Good fit: Ideal candidates are couples undergoing ICSI with their own fresh gametes, where the female partner is over 35 years old or the male partner is over 40 years old.

Not a fit: Patients using donor or frozen gametes, or those undergoing IVF cycles, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to higher quality embryos and improved pregnancy outcomes for couples facing infertility.

How similar studies have performed: While previous studies like the HABSelect trial showed no improvement in live birth rates with PICSI, they indicated a significant reduction in miscarriage rates, suggesting potential benefits in embryo quality.
