Abstract

For couples with a variety of male factor disorders, intracytoplasmic sperm injection has made pregnancy and motherhood possible. Two hundred-one males who had non-obstructive azoospermia or severe oligospermia were included in this study. One hundred forty trials of ICSI were done by using fresh sperms (fresh group n=140), while 61 trials of ICSI were done by using cryopreserved sperms (cryopreserved group n=61) to compare the conception rates between fresh and cryopreserved sperms used in intracytoplasmic sperm injection (ICSI). Twenty-five samples from each group were collected by doing a testicular biopsy. Pregnancy rates were higher using cryopreserved sperms as compared to fresh spermatozoa, 39.3% compared to 24.3% in the fresh group ( P .030), respectively. Binary logistic regression analysis showed that the odds ratio of achieving pregnancy with cryopreserved sperms was 2.022 higher than with fresh ( P .030). Cryopreservation has no negative effect on the pregnancy rate. Instead, it might improve the results of ICSI in comparison with a fresh sperm sample.
