A Comparative Study of Sibling Oocytes: ICSI vs. the IMSI Sperm Selection Method

A Comparative Study of Sibling Oocytes, Which Examines Two Sperm Selection Methods for Top Quality of Spermatozoa , Prior Intracytoplasmic Sperm Injection (ICSI) Performance, and Their Effect on Embryo Quality and IVF Outcome: A Common Selection Method Based on Morphology (ICSI) vs. an Ultra Morphology Section Method - Intracytoplasmic Morphology Selected Sperm Injection (IMSI)

Brief summary

The aim of this research is to compare sibling oocytes using two sperm selection methods for choosing the best quality spermatozoa before they are injected into oocytes and the influence of each of these methods on embryo quality and IVF outcome.

Interventions

OTHERIMSI Procedure

Injection of sperm that has been selected by the MSOME method into oocytes

OTHERStandard ICSI procedure for sperm injection into oocyte

The ICSI procedure is the standard procedure of selection and injection of sperm into oocytes

DEVICEMSOME

Selection of ultramorphologically normal spermatozoa using an inverted microscope with 6300x magnification

Design outcomes

Primary

MeasureTime frameDescription
Comparison of fertilization rateThree yearsInjected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The fertilization rates of the ICSI and IMSI methods will be compared.
Comparison of embryo qualityThree yearsInjected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The embryo quality of the ICSI and IMSI methods will be compared.

Secondary

MeasureTime frameDescription
Implantation rateThree yearsInjected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The implantation rates of the ICSI and IMSI methods will be compared.
Pregnancy rateThree yearsInjected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The pregnancy rates of the ICSI and IMSI methods will be compared.
Miscarriage rateThree yearsInjected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The miscarriage rates of the ICSI and IMSI methods will be compared.
Live birth rateThree yearsInjected sibling oocytes are incubated in a time-lapse incubator which enables ongoing observation after fertilization and cleavage of each oocyte. The live birth rates of the ICSI and IMSI methods will be compared.
