The Effect of Old Male Fertility on Stored Embryos
The decline of male fertility is a phenomenon that appears with the growth of age. More and more men delay their birth plans, leading to the gradual increase of the phenomenon of older boys' childbearing. This has brought some challenges and impacts to the storage and use of embryos. This article will elaborate on the influence of male elder childbearing on stored embryos from four aspects: fertility conditions, quality control, embryo freezing technology and legal provisions.
Fertility conditions
With the growth of age, male fertility will gradually decline. Some studies have shown that the aging of men will affect the quality and quantity of sperm, leading to the decline of sperm vitality and the rise of chromosome abnormalities. For male elderly couples, they may need to achieve fertility through artificial assisted reproductive technology. This may involve the use of donor sperm assisted reproductive technology, or assisted reproduction through in vitro fertilization and other methods. Therefore, the elder childbearing of boys will have a certain impact on the source and quantity of stored embryos.
In addition, older men are also prone to other health problems, such as cardiovascular diseases and metabolic disorders. These potential health problems may affect the storage and use of embryos. Therefore, male elderly couples need to undergo a comprehensive physical examination before giving birth, and assisted reproduction is carried out under the guidance of doctors.
Quality Control
The quality control of embryos in vitro culture is very important, which directly affects the success rate of assisted reproduction. The embryo quality of male elderly couples in assisted reproduction may be affected to some extent. The study found that the aging of men may lead to an increase in the rate of sperm chromosome abnormalities, which will lead to a decline in the quality of embryos produced. In addition, the sperm quality of elderly men will be damaged, and will also affect the development and quality of embryos. Therefore, when storing embryos, they need to be strictly screened and evaluated to ensure their quality and development potential.
Embryo freezing technology
Embryo freezing technology is one of the commonly used technologies in assisted reproduction, which is used to save surplus embryos for future use. For male elderly couples, embryo freezing technology can provide them with more opportunities to achieve family planning. However, the old age of men may lead to a decline in the quality of embryos, thus affecting the success rate of freezing and thawing. During freezing and thawing, embryos are vulnerable to damage and deformation, so the success rate of freezing and thawing may be low for embryos with poor quality. This has certain limitations on the success and use of stored embryos.
Legal provisions
Every country and region has certain legal provisions on assisted reproductive technology and the use of embryos. Whether the use of stored embryos is restricted for elder boys needs to be judged according to local laws and regulations. Some countries or regions may have age limit on assisted reproduction for elderly men. Therefore, if the frozen embryos are to be used for assisted reproduction, the elderly male couples need to understand and comply with local laws and regulations to ensure legality and compliance.
Summary
The older boys have a significant impact on the storage of embryos. From the four aspects of fertility conditions, quality control, embryo freezing technology and legal provisions, old men will have an impact on the source and quality of embryos, challenge the success rate of embryo freezing and thawing, and need to comply with local laws and regulations. Therefore, it is necessary to fully understand the relevant issues when giving birth to older boys, and conduct assisted reproduction under the guidance of doctors to improve the success rate and use effect of stored embryos.
