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.
