Study Of Semen Quality Of Fertile Men And Influencing Factors In Henan Province

BackgroundIn recent years,the decline of male fertility has become a global concern,and semen quality is the most basic indicator of male reproductive health.Scholars at home and abroad have not achieved consistent results on the degree of decline in semen quality and the influencing factors.At present,most studies believe that the main reason for the decline in semen quality are genetic and environmental factors,while lifestyle-behavioral factors are attracting more and more attention.ObjectiveTo study the semen quality and the influencing factors of the current fertility man,and evaluate the risk factors in relation to reproductive health,We also want to know whether the hot food,fried food,mobile phone,physical exercise,sleep quality or other factors influnced semen quality.providing guidance of eugenic and superior nurture for the current fertility men,and provided basic information for male reproductive health promotion.MethodsThe participants for this study were from Puyang maternal and child care hospital reproductive health center,using a unified socio-psycho-behavioral questionnaire by specially trained investigators for epidemiological investigation.The questionnaire mainly includes basic demographic data,disease history,and lifestyle,etc.At the same time,Semen samples were collected and analysed when the subjects were asked to abstinent for2-7 days.Semen samples were analyzed by the computer aided semen analysis technology,mainly including sperm concentration,vitality,movement parameters and sperm morphological parameters.SPSS19.0 was used to make statistic analysis.Kruskal-Wallis rank sum test and Analysis of Variance(ANOVA)were use to compare difference between groups,and influencing factors were analyzed by Logistic regression and multiple linear regression.Results1.A total of 548 volunteers completed all the surveys.The average age for all the subjects were 29.48 and 40.51%of them were between 25 to 30 years old.56.51%of households have an annual income below 50,000 Yuan,and 8.90%have an annual income above 150,000 Yuan.47.96%of the participants had the secondary education background..In the tea drinking habits of study subjects,the three conditions of‘never drinking tea',‘drinking tea',and‘once drinking'were basically evenly distributed.Those who did not drink cola and coffee accounted for 61.31%and 89.20%respectively,those who smoked accounts for 50.18%and those who drinked accounts for 43.53%.Abstinence days concentrated in 4-5 days accounted for 41.79%,sleep time concentrated in 6.5-8.0 hours accounted for 62.41%.Participants who have normal body mass index(BMI)accounted for 42.29%and overweight person accounted for 52.25%.2.In respect to the medians of the semen parameters,semen volume was 3.0 mL,sperm concentration was 58.3×10~6/mL,total number of spermatozoa was 207.5×10~6,forward movement sperm percentage was 50.2%,not forward movement sperm percentage was 11.4%,total sperm activity was 63.25%,and normal sperm morphology was 2.0%.3.After adjused for age,smoking/alcohol habits.Multivariate binary Logistic regression showed normal body weight was the protective factor of semen volume.Occupation were related to sperm forward movement.Increasing frequency of wearing tight underwear was the risk factor of sperm concentration and total sperm count.Wearing chemical fiber underwear was related to semen volume and sperm morphology.The increase of hot water bath frequency was the risk factor of sperm morphology.There was a statistical correlation between the intensity of physical exercise and semen volume,sperm concentration,percentage of forward-moving sperm and total sperm motility.The frequency of fried food consumption was related to sperm concentration,barbecue food consumption frequency was related to sperm count,percentage of forward-moving sperm,total sperm motility and normal morphology of spermatozoa.The internet time increased of mobile phone was the risk factor of sperm concentration and the quality of sleep was the influencing factor of sperm motility.Multivariate linear regression analysis showed that sleep quality was positively correlated with spearm neck defects.plastic container and fried food were releatd to VCL,VAP and ALH.ConclusionSperm concentration,vitality,movement parameters basically meet the standards for the world health organization's fifth edition,and spermatozoa shape deformity rate was higher,more higher than the world health organization recommends standards.Fried food,sleep quality,mobile Internet time,may have effect on sperm quality and sperm morphology.The influence of life behavior factors on semen quality needs to be further studied in a larger population.
