Methods Male infertility couples from October 2006 to July 2008 were chosen and divided into ICSI group and TESA+ICSI group. ICSI group were 584 oligozoospermia cases with alive normal sperm in spermatic fluid. TESA+ICSI group were 54 obstructive azoospermia cases with alive normal sperm in testicle. Two groups were treated with ICSI after wives obtained oocytes by ovarian stimulation.

Ninety-three patients with forty-two azoospermia and fifty-one severe oligozoospermia were recruited in present study. Y chromosome microdeletions were screened by detection of four locus SY84, SY134, SY255 and SPGY1 gene spaning the AZFa, AZFb and AZFc subregions of Y chromosome. The total incidence of Y microdeletions was 16%( 15/93 )in present study. Eight men in 42 patients with azoospermia had Y microdeletions, of whom 6 were AZFc deletion and 2 were AZFb deletion.
