The most direct evidence for whether a man belongs to infertility patients is the quality of sperm. Some semen test subjects may not understand the test results after receiving the report form, and may feel a bit shy when asking the doctor. They are embarrassed to inquire in detail.
Now, experts teach you how to understand the test sheet and examine the quality of your sperm:
1. Semen volume. On the 6th day after not ejaculating within 5 days, if the ejaculation volume reaches 3-5 milliliters, usually not less than 1.5 milliliters, it is considered normal ejaculation volume; On the contrary, it can be seen as a decrease in semen.
2. Semen color and viscosity. Normal semen is in a gray white jelly shape, which usually liquefies into a transparent liquid after 10 minutes. If the semen is not ejaculated for a long time (about 1 month), the first time it is ejaculated is light yellow, which is also normal.
3. Acidity and alkalinity. Normal fresh semen is slightly alkaline, with a pH value between 7.2 and 8.9, with an average of 7.8. When acidic, sperm motility and metabolic rate decrease, while when alkaline, they increase. Overalkaline has the opposite effect. Fresh semen will be acidified by itself after being put aside for a while, which will affect sperm motility. So when checking semen, it must be fresh semen and generally should not exceed 1 hour.
4. Sperm count. In general medicine, it is believed that a normal adult male contains 60 to 150 million sperm per milliliter of semen. There are only 10 to 40 million sperm per milliliter of semen, which also have fertility. People with less than 10 million sperm per milliliter are almost infertile, and those with azoospermia are absolutely infertile.
5. Measurement of sperm survival rate and motility. The survival rate of normal human sperm should be above 85% to 90%, but the motility of surviving sperm still varies. During medical testing, the strength of sperm motility is usually represented by symbols such as 0,+,++,++,++,+++, etc.: "0" level indicates no motility, such as dead sperm; '+' indicates poor activity ability; '++' indicates moderate vitality; '+++' indicates good vitality. In addition, the method of "climbing test" of sperm can also be used to observe the strength of sperm motility.
6. Sperm morphology:
① Normal sperm: The front of the head is ovoid, the side is flat, and the tail is long and curved, resembling a tadpole.
② Immature sperm, also known as immature sperm: its head is extremely small, or it has an additional "cap", or it has an appendage on its body.
③ Aging type sperm: The head is deeply colored with many black spots, but there are also cases where the head is not colored at all, like vacuoles.
④ Abnormal sperm: One or more parts of its head, body, and tail have morphological variations. If the sum of various types of abnormal sperm does not exceed 20% of the total sperm count, it can be considered a normal phenomenon. Semen contains a small number of white blood cells, and the average number of white blood cells in the high-power field of view is not more than 5, which can be considered normal. If there are too many, it can also affect fertility.
