ICSI Cycles Using Motile Sperm from Fresh Ejaculate in Cryptozoospermic Patients and the Extremely Severe Oligospermia Patients Yield Similar Reproductive Outcome

Abstract

Objective: In this retrospective study, we analyzed the in vitro fertilization (IVF) clinical and laboratory outcome of cryptozoospermia cases compared to the extremely severe oligospermia cases in a single IVF center. Materials and Methods: All the IVF laboratory and clinical outcomes of cryptozoospermia and extremely severe oligospermia cases were analyzed and compared between January 2014 and December 2019 in Istanbul Florence Nightingale IVF Center. The same reproductive group treated all couples. Virtual azoospermia or cryptozoospermia were diagnosed once the mature sperm cells could be recognized after centrifugation (group 1). Patients without motile sperm were excluded. Extremely severe oligospermia was defined as a sperm count was less than
