Table 2 Results of ICSI cycles using frozen-thawed sperm retrieved by Hotchkiss modified technique

From: Successful pregnancies and healthy live births using frozen-thawed sperm retrieved by a new modified Hotchkiss procedure in males with retrograde ejaculation: first case series

Patients Number of ICSI cycles performed Fertilization rate (nb of 2PN zygotes/nb of mature oocytes) for each cycle Number of embryos obtained for each cycle Number (and quality*) of embryos transferred for each cycle Number of frozen embryos for each cycle Clinical pregnancies for each cycle Live births (sex) for each cycle Number of thawed embryos transferred for each cycle Pregnancies after transfer of thawed embryos for each cycle Live births after thawed embryo transfer
