Purpose To compare semen quality with different abstinence times to provide suggestion to treat infertile couples. Methods Semen quality of all 562 men who aged 20 - 30 years old enrolled from 7 provinces were tested. Results Semen quantity, semen density and total semen count were all statistically increased with the longer abstinence time. The semen quantity indices(semen volume,semen density and total sperm number) was higher in the 5 - 6 days of abstinence, but semen quality indices have no statistical difference in the 3 - 6 days of abstinence. Conclusions Men with less sperm numbers maybe have a longer days of abstinence but not longer than 7 days. Those who have enough sperm numbers but poor sperm viability may have a abstinence time no more than 3 days which is very helpful to treat infertility couples to pregnant.
