Semen Analysis – Semen is a thick white liquid that males ejected from the penis. This process is called Ejaculation, which contains sperm, and the sperm carries genetic material. When the sperm and the female egg are bound together, they form an embryo (i.e. the initial stage of the development of an unborn baby).
Semen Analysis, which includes Sperm Count, measures the quality and quantity of semen and sperm in a male. If the male sperm is too small and the shape is abnormal, the sperm activity can make it difficult for girls to get pregnant, and semen analysis can help to identify the causes of male infertility.
The use of semen analysis
In addition to confirming whether there is a problem with semen or sperm and what causes infertility in boys, this analysis is also used to test whether vasectomy (Vasectomy, commonly known as male ligation) can be a suitable option for them; because vasectomy is designed to prevent sperm from being emitted into semen for contraceptive effect, semen analysis is necessary after surgery to confirm the effectiveness.
When to do semen analysis
If you want to have a child with your other half, yet your efforts for more than a year have not worked, it is advisable to consult a doctor for semen analysis.
Precautions for Semen Analysis
Prepare in advance
Before you perform a semen analysis, your doctor will inform the subject of what to do. Follow these steps to improve the accuracy of your analysis:
Avoid ejaculation 24 to 72 hours (i.e. 2 to 3 days) before the test.
Avoid drinking alcohol and taking too much caffeine 2 to 5 days before the test.
Stop taking any herbal related medicines such as St. John’s wort and Echinacea.
Avoid taking any hormonal drugs.
If you are taking medications, please discuss with your doctor first.
The process of semen analysis
The patient is required to provide a semen sample to the doctor for semen analysis. First, to get a good sample, there are 2 main factors that are important and should not be overlooked.
Semen must be stored at the same temperature as the body temperature. If the environment is too hot or cold, the test results will be inaccurate.
Semen must be sent to the testing body within 30 to 60 minutes after ejaculation.
Of course, you can choose to test sperm at home, but this method only counts the number of sperm and does not analyze the kinesis or shape of sperm. The results are usually available within 10 minutes. However, since this method does not consider all the reasons for infertility in boys, it does not adequately reflect the infertility of the subject. However, we recommend seeking professional medical assistance to assess fertility through professional testing.
If you have received a semen sample, the results should be available within 1 day to 1 week depending on the speed of the body. If you have any questions about the semen analysis, please consult a doctor to clarify the results.
Results of semen analysis
How do I analyze test results of a semen sample?
When examining the results of semen analysis, doctors consider many factors. If the test is performed for vasectomy, the most important thing is to see if there is no residual sperm in the semen, but if fertility is to be assessed, the Physicians consider many of the following factors:
Number of sperm
Normal semen contains between 20 million and 200 million sperm. If the number of sperm is too low, it can cause fertility difficulties.
The normal amount of semen should be greater than 2 ml. A small amount of semen means that the number of sperm that can be combined with the egg is small, while excessive amount of liquid means that the sperm may be diluted.
Semen activity dynamics
The normal result should be 1 hour after ejaculation, more than 50% of the sperm must be active normally. Sperm activity is very important for fertility, because sperm must go a certain distance to fertilize the eggs. Semen analysis can divide sperm activity into 0 to 4 levels, 0 means sperm inactivity at all, and level 3 to 4 represents a strong activity.
It is normal if more than 50% of the sperm shape is normal, but if more than 50% of the sperm shape in a boy is abnormal, it means lower fertility. To identify abnormal sperm shape, the laboratory finds the tip from the shape of the sperm’s head, body or tail. In addition, if the sperm is not mature enough, the egg cannot be fertilized effectively.
Acid and base value
The normal pH of semen should be between 7.2~7.8, higher than 8.0 indicates that the donor may have infection, and below 7.0 indicates that the sample may be contaminated, or the male ejaculation tube is blocked.
Semen should be liquefaction within 15 to 30 minutes. Semen first looks thick and its ability to liquefaction helps sperm activity, if it does not liquefy, it may affect fertility.
Normal semen is between white, gray, and milky. If semen appears reddish brown, it may contain blood, while yellow may be caused by Jaundice or side effects of drugs.
Abnormal results may indicate that the subject has the following conditions:
Patients with diseases such as Diabetes
Exposure to radiation
If the test results are abnormal, your doctor may recommend additional tests, including the following:
Routine urine examination after ejaculation (Urinalysis)
Tome samples of the testicles are examined
Anti-sperm Immune Cells Test
The normal range of semen analysis results will vary depending on the hospital or test unit. If you have questions about the results, please discuss with your doctor.
