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

Hillel Yaffe Medical Center50 enrolled

Overview

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.

Outcomes

Primary Outcomes

Comparison of fertilization rate

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.

Time frame: Three years

Comparison of embryo quality

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.

Time frame: Three years

Secondary Outcomes

Implantation rate

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.

Time frame: Three years

Pregnancy rate

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.

Time frame: Three years

Miscarriage rate

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.

Time frame: Three years

Live birth rate

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.
