Whether the quality of sperm can reach a normal level is a condition for men to have normal fertility. If the quality of sperm is not good, it is highly likely to cause male infertility. Therefore, men need to undergo a sperm test before considering fertility. So how to detect abnormal semen? Let's take a look at the expert's introduction below.
How to detect abnormal semen?
Within 60 minutes after ejaculation, more than half of male sperm will have the ability to move forward, and more than a quarter of sperm will have rapid forward movement. If sperm motility is weakened or there are too many dead sperm, it is the main cause of male infertility.
How to detect abnormal semen? Before checking the quality of sperm, semen should be taken first, and male friends should pay attention not to ejaculate within 5 days before the examination. Generally collect semen. After semen is collected, it should be placed in a dry and clean bottle and immediately sent for examination. The main inspection items include the following:
1. Analysis of chromosomal factors: anti sperm antibody test. People who are positive for anti sperm antibodies often have other problems at the same time, and some are also closely related to this positivity. For patients with extremely poor sperm quality, low sperm count, and a large number of abnormal sperm, although the possibility of chromosomal abnormalities is ruled out, anti-sperm antibody testing must be carried out, because positive anti-sperm antibody itself can completely lead to this, and positive anti-sperm antibody may also be accompanied by other problems.
2. Check for gonadotropins: How can abnormal semen be detected? When the number of sperm is too low, the motility is too low, the sperm is deformed in large numbers, or there are no sperm at all, chromosomal issues should be considered. The common chromosomal abnormality is 47, XYY type. Once confirmed by examination, treatment is not necessary because treatment cannot be effective.
3. Conducting special item testing: Conducting gonadotropin testing has important value in determining the functional status of the male hypothalamic pituitary gonadal axis. By observing the levels of follicle stimulating hormone, the degree of testicular development or damage can be understood.
