2 days or 3 days abstinence better for sperm wash

In other clinical conditions, however, the percentage of males affected was similar to the general population [ 18 ]. IUI time, sperm wash, semen parameters Introduction Intrauterine insemination IUI is a method that has been used for infertile couples in fertility treatment for many years. Intrauterine insemination IUI pregnancy outcome is enhanced by shorter intervals from semen collection to sperm wash, from sperm wash to IUI time, and from semen collection to IUI time. In this study, which appears in the June issue of Fertility and Sterility, researchers looked at whether sperm quality is affected by the duration of sexual abstinence necessary to reach maximum sperm quality. The data were analyzed by general linear models. But, a few studies suggest that this interval should be shorter 8. Results The median age of males was 32 years range 23—

Semen volume and concentration and total sperm count showed significant increases, whereas motility and normal morphology decreased significantly with duration of abstinence. The study indicates that the influence of long sexual abstinence on semen quality varies with the variable considered. Among the men with low sperm counts, abstaining for two days or more reduced both the motility of the sperm - how well it can swim to the egg - and a measure called the acrosome index, which reflects what proportion of the sperm have the necessary machinery to penetrate the egg. Significant changes in the percentage of normal sperm forms were observed after more than seven days' abstinence. A rating of 0 or 1 is considered normal some minor clumping is not unusual. By looking at 1, semen samples from men they found pausing from sex for no more than a day was best.

More than of the samples were normal, while the rest showed low sperm counts to varying degrees. The variations in semen parameters were analyzed statistically as a function of the duration of abstinence. I think the following differential equation can describe the change of the sperm count: Longer or shorter periods can affect all the critical numbers above, usually making them lower.
