OBJECTIVE: To ascertain the epididymal sperm nuclear maturity in obstructive azoospermia (OA) patients.
METHODS: A total of 81 infertile males from andriatry clinic of Renji hospital were selected, including 32 OA patients (OA group) and 49 asthenospermia patients (asthenospermia group). Another 32 fertile males were recruited for the control group. All semen samples of the asthenospermia and control groups underwent computer aided semen analysis (CASA). For the OA group, sperm specimens were collected by percutaneous epididymal sperm aspiration (PESA) and semen analyses completed by manual method. Further acridine orange test and aniline blue stain assay were performed. The results were processed with SPSS 15.0.
RESULTS: No statistically significant differences existed in semen volume and sperm density between the asthenospermia and control groups (both P > 0.05). The OA group was significantly lower than the control group in sperm density (P < 0.01). The asthenospermia and OA groups were also significantly lower than the control group in sperm motility (both P < 0.01). As to the percentage of grade a + b sperm, the asthenospermia group was also significantly lower than the control group (P < 0.01). Compared with the control group (81% ± 9%, 85% ± 8%), the negative rate of acridine orange test and aniline blue assay of OA (57% ± 20%, 64% ± 20%) and asthenospermia group (62% ± 19%, 67% ± 15%) were statistically lower (all P < 0.05).
CONCLUSIONS: The sperm nuclear maturity is lower in the asthenospermia and OA groups than that in the control group. Male fertility should be further improved.
