Evaluating Piezo-ICSI. - The EPI Study.

Infertility Clinical Trial

Official title:
Will Piezo-ICSI Increase Fertilization Rates Compared to Conventional ICSI? A Prospective Randomized Sibling Study.

Clinical Trial Summary

Intracytoplasmic sperm injection (ICSI) has successfully been used to treat both severe male infertility and fertilization failure since its introduction in the early 1990´s. During the procedure a single sperm is injected into the cytoplasm of an oocyte to achieve fertilization. This technique is intrusive, has a relatively long learning curve and variable operator performance. A new injection technique called piezo-ICSI has recently been introduced. During piezo-ICSI, a piezo-electric effect is generated through the conversion of electric energy to mechanical energy. This causes a smooth movement of the injection pipette, which allows for steady, controlled microinjections with less psychical stress applied on the oocytes than by the conventional technique. A recent analysis, based on data from 9 different studies comparing conventional ICSI and piezo-ICSI (17500 cases), showed a benefit of piezo. Unfortunately, proper randomized trials are missing from this analysis. The proposed study is a randomized controlled study carried out at two private IVF clinics. Eligible participants are patients undergoing ICSI treatment, with a minimum of 6 oocytes. The participants will act as their own controls, with their oocytes randomly and equally divided between injection by the investigated and the conventional technique. Whether piezo-ICSI is associated with improved success rates or reduction in adverse outcomes is at present unclear. Patients with fragile oocytes may benefit more from piezo-ICSI. In patients above 35 years, piezo-ICSI has been associated with a lower oocyte degeneration rate and an increased blastocyst rate. The aim of the study is to investigate whether the piezo-ICSI technique will result in more oocytes becoming normally fertilized compared to conventional ICSI. Another proposed benefit of piezo-ICSI lies in the standardization and simplification of the ICSI procedure. Making the injection procedure more independent of operator skill may result in a more robust and predictable laboratory output.
