How many days do men abstain from testing sperm quality? Here are the precautions for semen examination

Routine semen analysis is an important test to evaluate male fertility, and it is very important for the treatment of male infertility. So, how long before the semen test?

Experts pointed out that general semen examination requires abstinence for 2 to 7 days, and long abstinence will affect the determination of semen parameters, mainly affecting vitality.

Experts said that within one hour after male ejaculation, the number of active sperm must be more than half, and the number of active sperm below half is abnormal, also known as low sperm motility, also known as weak sperm. Sperm will die if it has no activity at all. Low sperm motility and spermatozoosis are one of the important causes of male infertility.

The analysis of the density, vitality, morphology and other major indicators of semen routine analysis, combined with the medical history. Without medical history, simple analysis and examination is very naive, and it is an irresponsible treatment attitude towards patients. First of all, semen is usually not a functional test, but a rough judgment of fertility through sperm density, vitality, morphology and other indicators, which is just like judging a person by appearance. It is not correct. Second, semen analysis usually cannot determine the fertility of a few sperm reaching the fertilization position. Therefore, correct evaluation of male fertility needs to be combined with clinical data such as medical history.

The definition of male infertility does not specify the specific parameters of semen. Semen is usually only a reference for the evaluation of male fertility, which has many limitations and must be determined in combination with medical history. Medical history mainly refers to the time when no contraceptive measures were taken. We have observed in clinical practice that many infertile men with low gonadotropin can conceive if there is sperm in the semen after treatment. If there is a medical history that proves the importance of the medical history, the routine parameters of male semen are normal, and there is no major theme for women, which indicates that there are unknown infertility factors now

This needs exaggeration, and the selection must be complete. Because when the semen is ejected, the first discharge is clear and viscous, mainly the secretion of the bulbar gland of the urethra and a small amount of prostatic fluid, which is a sign of male sexual excitement. The quantity of sperm is very small, which plays a role in lubricating the urethra and is conducive to ejaculation. The second is the most important part of ejaculation, mainly the prostatic fluid and epididymal tail fluid. The quantity and quality of sperm is the best, and the last is the secretion of the seminal vesicle gland which is coagulated and dissolved, It mainly contains fructose, the quantity of sperm is small, and the quality is not good.
