摘要:To investigate the relation of luteinizing hormone (LH), follicle-stimulating hormone (FSH) and Testosterone serum levels with partial deletions in the AZFc region in Iranian oligozoospermia males. Material and methods: thirty infertile oligozoospermia and 52 Iranian fertile men included. The hormonal assays were measured by the Radioimmunoassay (RIA). Multiplex polymerase chain reaction (M-PCR) using eight sequence-tagged site (STS) markers were measured on the Yq11 chromosome. Results: The mean of FSH and LH levels in all oligozoospermia males were higher than fertile men (p < 0.001) and testosterone was lower significantly (p < 0.001). Five patients showed partial deletions in AZFc region (four had gr/gr and one had b2/b3 deletions). Six fertile men showed partial deletions (five gr/gr and one b2/b3) with higher level of FSH, LH in their group (p < 0.05). Conclusion: According to high incidence of partial deletions in the AZFc region among Iranian oligozoospermia males, hormonal assay and molecular screening should be advised before considering for ART treatments.
