MethodsA total of 166 patients with oligozoospermia who underwent an ICSI procedure were included in the study. The subjects were divided into two groups according to the sperm retrieval technique used: group 1, ejaculated semen (n=111); group 2, surgical sperm retrieval (n=55). ResultsAlthough the clinical pregnancy rate was lower in group 2, the difference was not statistically significant (36.4% vs. 42.3%, p=0.460). The difference between fertilisation and take-home baby rates of the groups were not significantly different, either (p=0.486, p=0.419, consecutively). ConclusionTwo different sperm retrieval techniques used for ICSI had no statistically significant difference on intracytoplasmic sperm injection outcomes in oligozoospermic patients. ER -
