Abstinence on semen quality of men

Different, which in the clinical treatment of infertility will have a certain significance. Abstinence time is too short, insufficient supply of components of semen, semen volume can be significantly reduced. The small number of sperm, sperm density decreased, immature sperm increased, the negative conception. Prolonged abstinence, semen increased, decreased sperm density, sperm aging, the number of dead sperm and abnormal sperm increased, decreased activity, therefore, abstinence too long and too short not conducive to conception. High Banghua so ... 1 of 50 normal men, sperm were for 1 year of observation, found that abstinence on semen volume had no effect, and the sperm density and total sperm count are presented along with abstinence time increasing trend. Blackwell and other 【2J found that as abstinence time, semen volume, sperm density and sperm have increased the total number, including abstinence,[link widoczny dla zalogowanych], semen volume and sperm density after 10d when compared with an increase of 1 1d abstinence times, while the total number of sperm increased by 4 times. Pellestor other L3J of six different men, abstinence time (1 ~ 18d) of the semen quality of analysis indicated that the duration of abstinence on sperm quality parameters were all affected by the time sheets with abstinence, semen volume and concentration and total sperm count increased significantly,[link widoczny dla zalogowanych], but sperm motility and normal morphology decreased significantly. In abstinence for more than 7d, the percentage of normal sperm morphology changed significantly. Raziel and other J in a prospective cohort study, 50 cases of nonobstructive azoospermia abstinence syndrome male patient with a determination of the different times the number of sperm cells collected, sperm motility,[link widoczny dla zalogowanych], total sperm count,[link widoczny dla zalogowanych], the results showed that sperm count (P < 0.025), total motile sperm number (P <0.025) increase in abstinence time with a significant difference in sperm motility but no significant difference. This study found that as abstinence time, semen quality indicators in the index number of sperm (sperm density, total sperm count) increase in abstinence higher at 5 and 6d. Sperm forward motility of sperm quality index percentage difference in abstinence 3 ~ 6d although there were significant differences, but the difference is not absolute. Multivariate logistic regression analysis found that as abstinence time, sperm density, total number of sperm, and study abroad consistent with the results. In addition, the study also found that the percentage of sperm forward movement with the increase in the number of days of abstinence showed different changes in the abstinence section 3d, the highest, and in the abstinence 4 - 6d a slight decline when. Therefore, the small number of male sperm, abstinence time can be longer, but not more than 7d, so that sperm concentration, sperm count and will be increased; poor sperm motility of male sperm count enough, abstinence time can be shorter, 3d about can be. Because for too long will lead to aging sperm, dead sperm counts and abnormal sperm increased, activity decreased. Therefore, for clinical male infertility should be based on the actual situation of its time to take a different abstinence may increase the chances of conceiving. Thanks Henan, Zhejiang, Shanxi, Hebei, Guizhou, Qingdao, five provinces and one city family planning clinics and research health and epidemic prevention station in Taiyuan City participated in the study.
