[SHENG MAI ZHUSHEYE improves the viability and movement parameters of human sperm in vitro].

OBJECTIVE: To observe the effect of SHENG MAI ZHUSHEYE on the movement parameters and viability of human sperm in vitro. METHODS: We collected sperm samples from 33 normal fertile men, divided each into two, and cultured them in vitro with SHENG MAI ZHUSHEYE + Hams-F10 and Hams-F10 alone, respectively. Then we measured the straight line velocity (VSL), curvilinear velocity (VCL), average path velocity (VAP) and the amplitude of lateral head displacement (ALH) of the sperm by computer-aided semen analysis at 0.5, 1, 2, 4, 8 and 12 h. And the sperm viability was detected. RESULTS: VCL was significantly higher at 8 h (P < 0.05) and very significantly higher at 12 h (P < 0.01) in the SHENG MAI ZHUSHEYE + Hams-F10 group than in the Hams-F10 group. VSL, VAP and ALH were significantly increased in the former group at 4, 8 and 12 h as compared with the latter (P < 0.05). The sperm viability was significantly decreased in the Hams-F10 group at 12 h (P < 0.05). CONCLUSION: SHENG MAI ZHUSHEYE can improve sperm movement parameters and increase sperm viability in vitro.

[Prevalence of bacterial vaginosis in married women of reproductive age in the rural area of Shandong province and its risk factors].

OBJECTIVE: To explore the prevalence of bacterial vaginosis of married women of reproductive age in the rural area of Shandong province and its affecting factors, with an aim to provide references for setting up preventing measures for this disease. METHODS: A stratified, population-based, cluster sampling method was employed. The epidemiological investigation on bacterial vaginosis of married women of reproductive age was carried out at four sampling fields. RESULTS: The prevalence of bacterial vaginosis was 6.64%. The main risk factors included: lacked of personal bathtub and towel; did not use sterilized paper on menstrual phase; had no knowledge that gonorrhea, syphilis, AIDS, and trichomonal vaginitis can be transmitted through sexual intercourse. CONCLUSION: The prevalence of bacterial vaginosis in married women of reproductive age in Shandong rural area is high, which correlates with the lower education level, limited health knowledge, and unhealthy behavior.
