Semen liquefaction time of 40 minutes is normal. Generally in the clinic if the semen liquefaction time is not more than 1 hour, are considered normal. Of course everyone’s sperm liquefaction time is different, some people may be a few minutes, some may be half an hour, some may be 40 or 50 minutes, so it’s not even the same, and the semen liquefaction time also fluctuates. There are times when you check your semen and this time it’s not liquefied, maybe the next time you check it it’s liquefied again, or it becomes incompletely liquefied, it all fluctuates. The mere fact that the semen is not liquefied is not really a particularly big problem. In fact, there may be a need to look for reasons that may affect the quality of semen, such as whether there is varicocele, whether there is any infection in the semen, whether there is any excess of white blood cells. Of course, there are also factors related to the function of the seminal vesicles, such as the secretion of some enzyme levels are not abnormal or too low, and so on, all these factors are related. Therefore, once in a while, if there is no liquefaction in the semen quality check, don’t worry. At this time, you can adjust your body and review the test a few more times, and maybe it may become liquefied later. So men need to know that sperm liquefaction time is considered normal as long as it does not exceed one hour.
