Seventy-three azoospermia and 28 severe oligozoospermia patients were evaluated using PCR and PCR-SSCP techniques.Results Twelve of 101 patients (12%) with the AZFc/DAZ microdeletion were found, including 8 with azoospermia (11%) and 4 with severe oligozoospermia (14.3%), and 1 patient had a AZFb and AZFc/DAZ double deletion. No deletions in the AZFa or SRY regions were found. No deletions in AZFa, AZFb, AZFc/DAZ or SRY regions were found in 60 normal men who had produced one or more children.Conclusions Microdeletion on the Y chromosome, especially at its AZFc/DAZ regions, may be a major cause of azoospermia and severe oligozoospermia leading to male infertility in China. It is recommended that patients have genetic counseling and microdeletion detection on the Y chromosome before intracytoplasmic sperm injection.展开更多

Method： Thirty-eight patients with seminal abnormality were separately treated by acupuncture and traditional Chinese medications （“Erxian Decoction”） plus Clomiphene. Results and Conclusion： The total effective rate was 96.0% in the acupuncture plus traditional Chinese medication group （26 cases） and 66.7% in the acupuncture and western medication groups （12 cases）. Statistical analysis showed a significant difference （P〈0.05）. The cure rate and the pregnancy rate were 38.5% and 30.8% respectively in the acupuncture and traditional Chinese medication group. Both of them were higher than 8.3% and 8.3% in the acupuncture and western medication group respectively, but there were no statistically significant differences. In the two groups of patients, seminal volume, liquefaction time and viscosity and spermatozoal density, death rate and one-hour survival rate took a significant turn for the better after treatment as compared with before treatment （P〈 0.05）. In the acupuncture and traditional Chinese medication groups of patients, symptoms markedly improved after treatment as compared with before treatment.展开更多
