Sperm is very important for every man, and the causes of male infertility are closely related to sperm. Sperm is the key to male infertility, and abnormal sperm should be the main cause of male infertility. So what is normal male sperm like? Knowing that normal sperm is necessary for every man.
Normal male sperm have their own normal standards for color, semen volume, pH, odor, etc. Therefore, only by understanding what normal male sperm looks like can men better identify problems with their semen.
How to determine whether male sperm is healthy?
1. Color: Normally grayish white, but may appear light yellow, milky white, or slightly green when ejaculated for a long time. Infections may occur in the reproductive tract or accessory gonads; Red semen (hematospermia) can be seen in seminal vesiculitis, cancer, tuberculosis, etc.
2. Semen volume: Normal individuals ejaculate 2-5ml per ejaculation. If it is less than 1ml, it is considered abnormal. Each ejaculation (0.5ml is spermatopenia, and if there is no semen, it is azoospermia. azoospermia and spermatopenia are the main causes of male infertility. It can be seen in prostate or seminal vesicle lesions, congenital ureteral obstruction or inflammatory stenosis, or retrograde ejaculation.
3. PH: Normally weakly alkaline, with a pH between 7.7 and 8.5. Excessive acidity or alkalinity of semen may affect sperm activity and metabolism, and is the main cause of sperm death (azoospermia).
4. Smell: Normal semen has a special fishy smell, which is emitted by prostatic fluid. This fishy smell comes from a certain component of prostatic fluid.
5. Sperm count: For men with normal fertility, there are 60-150 million sperm per milliliter of semen, sometimes up to 200 million. The total number of sperm produced in one ejaculation is about 300 million or more, but the content of sperm varies greatly from person to person, even if the same person has differences at different times. Therefore, calculating the total number of sperm expelled each time has greater diagnostic value than checking the sperm count alone.
Excessive sperm density (over 250 million per milliliter) is known as oligozoospermia, which often affects sperm motility and can lead to miscarriage even during pregnancy. The main reason for this is the low quality of the sperm itself.
6. Viscosity: Normal fresh semen appears as a liquid, rapidly turning into a viscous peptone like semi fluid after discharge, and then back into a liquid after 5-30 minutes. If it does not liquefy for 30 minutes, it is considered abnormal, as seen in the deficiency or insufficiency of certain enzymes secreted by the prostate, as well as in reproductive system tuberculosis, which can also affect fertility.
