What Is Semen Collection?

Semen is a secretion of the male reproductive system and is mainly composed of sperm and seminal plasma. Seminal plasma is a medium and energy source for sperm survival, and plays an important role in sperm survival and physiological motor function. The presence or absence of sperm is a sign of male fertility, but the intrinsic quality of semen and sperm is also an essential condition for male fertility. Semen examination generally includes routine inspection and special inspection. Semen routine examination (PRT) includes: semen discharge, semen color, pH value, sperm motility, sperm motility, microscopic examination (by observing sperm morphology, number, cell conditions, etc.), semen liquefaction time, etc. Routine semen examination is one of the simple and popular laboratory examination methods in urology, andrology, and reproductive medicine. In addition, the results of routine semen testing can only reflect the probability of fertility in male patients.
