Not Applicable
Conditions
Infertility
Interventions
Other: Standard ICSI procedure for sperm injection into oocyte
Device: MSOME
Other: IMSI Procedure
Registration Number
NCT03240276
Lead Sponsor

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.

ICSI ProcedureStandard ICSI procedure for sperm injection into oocyteThe ICSI procedure is the standard procedure of selection and injection of sperm into the oocyte
IMSI ProcedureMSOMEThe IMSI procedure is the injection of normal ultramorphological spermatozoa that have been selected using an inverted microscope with magnification of 6300x (MSOME)
IMSI ProcedureIMSI ProcedureThe IMSI procedure is the injection of normal ultramorphological spermatozoa that have been selected using an inverted microscope with magnification of 6300x (MSOME)
Primary Outcome Measures
NameTimeMethod
Comparison of fertilization rateThree years

Injected 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 years

Injected 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 Outcome Measures
NameTimeMethod
Pregnancy rateThree years

Injected 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.

Implantation rateThree years

Injected 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.

Miscarriage rateThree years

Injected 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 years

Injected 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.
