Abstract: Objective (s): evaluate the fertilization response, quality of embryos and pregnancy outcome during ICSI in comparison between fresh and frozen –thawed semen and measures it is the outcome: fertilization rate, embryos quality, implantation and pregnancy rate. Design: Prospective randomized study. Setting: assisted reproduction unit at the Fertility Clinic in International Islamic Center for Population Studies and Research, Al _azhar University Subject: evaluate sperm selection technique using fresh and thawing sperm in intra-cytoplasmic sperm injection (ICSI). The study population consisted of 100 couples. Results: The study population of 100 couples who referred to ICSI divided into 2 groups, normozospermia and oligozospermia, including complete semen analyses parameters,flow up and comparison between the changes after freeze-thawed sperm parameters, also ICSI outcome. Conclusion: Cryopreserving sperm plays an important role before IVF processing, avoids the need for additional surgery in couples and provides hope for men undergoing chemotherapy, radiation or radical surgery who once had no chance for future fertility.
