The risk of male elderly childbearing: at what age is it easy for men to have children?
With the development of society, it is more and more common for men to delay childbearing. However, it is not without risks for men to give birth at an advanced age. The male reproductive capacity will gradually decline as the age increases, increasing the risk of a series of fertility problems. This article will discuss the risk of male elder childbearing from many aspects.
Decreased sperm quality
With the increase of age, the quality of men's sperm will gradually decline, which is mainly manifested in the reduction of the number of sperm, morphological abnormalities and decreased vitality. A study found that compared with men aged 20-29, men aged 40-49 have twice the risk of oligospermia. In addition, more and more studies have shown that the proportion of chromosomal abnormalities in sperm produced by elderly men will also increase, which increases the risk of birth defects and mental retardation.
In addition, the increase of male reproductive age is also related to the decline of sperm DNA stability. Studies have found that with the increase of age, the phenomenon of chromosome breakage and recombination in male sperm will increase, which may lead to sperm DNA damage. The damage of sperm DNA will affect the normal development of embryos and increase the risk of abortion during pregnancy.
Therefore, the decline of sperm quality caused by the aging of male fertility is a very important fertility risk.
Increased risk of reproductive system diseases
The increase of male reproductive age will also increase the risk of a series of reproductive system diseases. For example, the probability of men suffering from prostate diseases and sexual dysfunction will increase with age. Prostate disease will affect the quality and quantity of semen, thus reducing fertility. Sexual dysfunction will lead to erectile dysfunction, which will affect sexual life and reduce the chance of pregnancy.
In addition, the elderly male fertility will also increase the risk of diseases such as testicular cancer and varicocele. These diseases may have a direct or indirect impact on fertility.
Increased health risk of offspring
Older men also increase the health risks of their offspring. Research shows that children born to older fathers are at higher risk of autism, mental illness and neurodevelopmental problems than young fathers. In addition, a study also found that children born to older fathers are more likely to suffer from chronic diseases such as heart disease, hypertension and diabetes.
These health problems may be related to chromosome abnormalities and DNA damage in male sperm. Therefore, the health risks of the offspring brought about by the elderly male childbearing cannot be ignored.
Increased birth difficulties
The probability of fertility difficulties will also increase when men are old enough to give birth. The decline of male fertility will lead to difficulty in pregnancy, thus increasing the time and opportunity for couples to become pregnant. In addition, the elderly childbearing in men is also related to postpartum depression in women and premature delivery of fetuses.
In addition, the elderly male fertility will also increase the risk of infertility. The study found that the phenomenon of DNA breakage and recombination in the sperm of elderly men increased, which may lead to abnormal sperm function, leading to infertility.
Summary
The risks brought about by the elderly male childbearing cannot be ignored. The main problems faced by older men in childbirth are the decline of sperm quality, the increased risk of reproductive system diseases, the increased risk of offspring health, and the increased difficulty in childbearing. In order to reduce the risk, men should choose the right birth time within the best childbearing age.
