1, sperm reduction and sperm increase: usually, the number of sperm contained in a male ejaculate is 20 million to 200 million / ml, sperm count below 20 million / ml is sperm reduction, more than 300 million / ml is sperm increase. 2, azoospermia: three semen examinations did not find sperm for azoospermia, azoospermia is also divided into “congenital azoospermia” and “obstructive azoospermia” two, the former refers to testicular spermatogenic cells atrophy, degeneration, can not generate sperm; the latter refers to testicular can produce sperm, but the vas deferens The former refers to testicular sperm cells atrophy and degeneration, unable to produce sperm; the latter refers to the testicles can produce sperm, but the vas deferens is blocked and cannot discharge sperm. 3, dead sperm: sperm viability in the semen is reduced, semen examination found in the dead sperm more than 40% is dead sperm, also known as dead sperm hyperspermia. However, the artificial increase in dead sperm due to improper examination methods or failure to collect semen according to normal methods is called pseudo-dead spermatozoa and must be differentiated. 4, hematosperm: semen mixed with blood, severe cases of semen visible to the naked eye with blood, known as “naked eye hematosperm”; mild cases of the naked eye is not visible, but with the help of the microscope visible red blood cells, known as “microscopic hematosperm”. 5, semen increase and semen decrease: generally the normal amount of semen is 2 to 6 ml, less than 1.5 ml is semen decrease, more than 6 ml is semen increase, semen increase is not equal to sperm increase. 6, semen is not liquefied: generally normal semen is a uniform flowing liquid, if the isolated semen at room temperature (22-25 degrees Celsius) for 60 minutes still does not liquefy or still contains liquefied agglomerates, it is called “semen is not liquefied”, affecting sperm agglutination or braking, slowing or inhibiting the normal movement of sperm. In men, ejaculation occurs when they reach orgasm during sexual intercourse. The actual fact is that you will not be able to experience the pleasure of sexual life for men with abnormal semen, so for the sake of your family and your body, please get treatment as soon as possible to avoid delaying the best time for treatment.
