Sperm defect severity rather than sperm source is associated with lower fertilization rates after intracytoplasmic sperm injection

1 Feb 2008

Abstract excerpt

OBJECTIVE: To evaluate the impact of sperm defect severity and the type of azoospermia on the outcomes of intracytoplasmic sperm injection (ICSI). MATERIALS AND METHODS: This study included 313 ICSI cycles that were divided into two major groups according to the source of spermatozoa used for ICSI: 1) Ejaculated (group 1; n = 220) and 2) Testicular/Epididymal (group 2; n = 93). Group 1 was subdivided into four...
