There is a lack of clarity regarding the justification to instruct the couple to shift from intracytoplasmic sperm injection (ICSI) to intracytoplasmic morphologically selected sperm injection (IMSI). In this study, we aim at evaluating the efficacy of IMSI in couples with previous implantation failure with ICSI.

Condition Intervention
Male Infertility Female Infertility Other: Intracytoplasmic morphologically selected sperm injection Other: Intracytoplasmic sperm injection

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: The Effect of the Intracytoplasmic Morphologically Selected Sperm Injection in Couples With Previous Implantation Failure After Intracytoplasmic Sperm Injection
