How to judge the fertility of men in the table of fertility standards for the elderly?
With the development of society and the progress of medicine, more and more men have postponed childbearing, but the fertility of men is not unlimited. In order to evaluate the fertility of men at an advanced age, the medical community has formulated a table of standards for the fertility of men at an advanced age. The table comprehensively considers the reproductive health status of men from multiple aspects to help doctors and patients timely assess reproductive risks and select appropriate treatment methods.
1、 Semen analysis
Semen analysis is an important means to evaluate male fertility. The sperm density, vitality, morphology and arrangement of semen have clear indicators in the table of fertility standards for older men.
First, sperm density refers to the number of sperm per milliliter of semen. Normal sperm density should be between 15 and 200 million/ml. If the sperm density is lower than this range, it means that the number of male sperm is insufficient, which may lead to the decline of fertility.
Secondly, sperm motility refers to the motility of sperm. Normal sperm vitality should be above 40%. If the sperm vitality is lower than this standard, it means that the fertilization ability of male sperm is poor, which may increase the difficulty of pregnancy.
Finally, sperm morphology and arrangement are also important indicators to evaluate male fertility. The proportion of sperm with normal shape and arrangement should be more than 4%. If the proportion of sperm with abnormal morphology and arrangement is too high, it indicates that the quality of male sperm is poor, which affects fertility.
2、 Hormone level detection
The table of standards for older men's fertility also includes the detection of hormone levels. Hormone levels play an important role in the normal functioning of male reproductive function.
Important hormones include testosterone, luteinizing hormone and prolactin. Testosterone is a male sex hormone, which plays an important role in spermatogenesis and sexual desire. Luteinizing hormone and prolactin regulate testosterone levels in men. If the hormone level is abnormal, such as the testosterone level is low, it may lead to the decline of male sperm production ability, thus affecting fertility.
3、 Genetic disease screening
The table of standards for older men also emphasizes the screening of genetic diseases. The risk of men suffering from some genetic diseases increases with age.
Common genetic disease screening includes detection of chromosome abnormalities and gene mutations of common genetic diseases. Chromosome abnormalities, including Klinefelter syndrome and Y chromosome microdeletion, can lead to a decline in the number or quality of male sperm. Detection of gene mutations in common genetic diseases can help patients understand whether they carry genes of genetic diseases.
4、 Genital examination
The reproductive organ examination is also included in the table of the fertility standards for older men. The health of the reproductive organs is crucial to male fertility.
The genital examination mainly includes the assessment of the size, shape and function of the testis, as well as the examination of the prostate and epididymis. The abnormality of reproductive organs may affect the function of sperm production, storage and transportation, thus affecting male fertility.
Summary
The table of fertility standards for men of advanced age is a guide for comprehensive evaluation of male fertility. Through semen analysis, hormone level detection, genetic disease screening and reproductive organ inspection, male fertility risk and fertility can be comprehensively assessed. Accurate assessment of male fertility will help doctors and patients to make wise decisions in the process of elderly childbearing.
