OBJECTIVE: To study the correlation of azoospermia and severe oligozoospermia with Y chromosome microdeletions, chromosome karyotype and reproductive hormones in male infertility patients.
METHODS: We collected semen samples from 63 patients with azoospermia, 49 with severe oligozoospermia and 60 men with normal semen parameters, and determined the incidence of Y chromosome microdeletions, chromosome karyotypes and the levels of reproductive hormones.
RESULTS: The incidence rate of Y chromosome microdeletions was 11.11% in the azoospermia and 8.16% in the severe oligozoospermia patients, as compared with 0 in the normal controls (P< 0.05). The rate of chromosome abnormalities was 9.52% in the azoospermia group, with statistically significant differences from the severe oligozoospermia and normal control men (both 0) (P< 0.05). The levels of FSH and LH were significantly higher in the azoospermia ([20.41 +/- 19.34] IU/L and [11.44 +/- 9.48] IU/L) and the severe oligozoospermia patients ([8.88 +/- 7.04] IU/L and [6.78 +/- 3.85] IU/L) than in the normal males ([3.88 +/- 2.21] IU/L and [4.63 +/- 1.51] IU/L) (P< 0.05).
CONCLUSION: Examinations of genetics and reproductive hormones are necessary for infertile males with azoospermia and severe oligozoospermia, which may contribute to early diagnosis and treatment.
