[Effects of cigarette, alcohol consumption and sauna on sperm morphology].

OBJECTIVE: To investigate effects of cigarette, alcohol consumption and sauna on sperm morphology. METHODS: 602 cases of male infertility were selected from our case database, who were divided into three subgroups: smoking (243) , drinking(224), sauna(135) and those without any of the above habits were taken as the corresponding controls. The sperm morphology were analyzed by automated sperm morphology analyzer(ASMA). A questionnaire was voluntarily filled out by patients in order to investigate cigarette, alcohol consumption and sauna frequency. RESULTS: The normal morphologic sperm rates in cigarette, alcohol consumption and sauna groups were lower than those in the corresponding control groups, respectively(P <0.05, P <0.001). Percentages of irregularity head sperm were higher than those in normal controls, respectively(P <0.05). CONCLUSION: Cigarette, alcohol consumption and sauna could affect sperm morphology, especially caused increasing of irregularity head sperm.

[Relationship between sperm motility parameters and sperm morphology].

OBJECTIVE: To evaluate the relationship between sperm motility parameters and sperm morphology. METHODS: Seven hundred and eighty-three semen samples were tested. Sperm motility parameters were analyzed by computer-aided sperm analysis (CASA) , and sperm morphology assessed by automated sperm morphology analyzer (ASMA). The cases were classified based on the World Health Organization criteria. Morphologically 241 of the samples were normal and the other 542 abnormal. RESULTS: VCL, WOB, VAP of the morphologically abnormal group were significantly higher than those of the normal group (P < 0.05, P < 0.001), while MAD, LIN, STR of the abnormal group were significantly lower (P < 0.05, P < 0.001). There were significant positive correlations between the morphologically normal sperm rates and MAD, LIN, WOB, STR, and a significant negative correlation between the morphologically normal sperm rate and ALH. CONCLUSION: Morphological abnormality of sperm is often accompanied with weak motility, which is probably attributed more to some factors that coact on both sperm motility and morphology than to the influence of sperm morphological abnormality on sperm motility.

[Zona pellucida and male fertilization].

Zona pellucida (ZP) plays a key role in the recognition, combination and penetration of sperms and oocytes, the prevention of multiple impregnation, the protection of embryos, and so on. The paper reviews the constitution, molecular structure, biological function and application of zona pellucida in male fertilization.

[Advances in research on sperm chromosomes in male infertility].

Many factors can result in male infertility, and a number of studies have indicated that reproductive difficulties are associated intimately with cytogenetic abnormalities. This article reviews studies on sperm chromosomes in infertile men and discusses the relationship between sperm chromosome abnormality and male infertility.

[Comparison on ingredients between cultured cell and cultivated Saffron pistils].

OBJECTIVE: To compare the differences of active ingredients between tissue cultured cells and cultivated saffron pistils. METHOD: The experiment was carried out by the Fourier transform infrared spectroscopy (FTIR) spectra and high performance liquid chromatography (HPLC). RESULT: The data indicated that the species and contents active ingredients in saffron pistils from different places were different. The species of active ingredients in tissue cultured cells are less than those in cultivated saffron pistils. However, the quantity of crocin A, which showed good anticancer effect, is 2-3 times more than that in cultivated saffron pistils. CONCLUSION: The active ingredients of the tissue cultured cells are similar to those of saffron pistils, but their contents are different. Therefore, the tissue cultured cells can only be the part-substitutes of cultivated saffron pistils.
