The causes of fertility difficulties in older men
1. Decreased reproductive system function
With the increase of age, the function of male reproductive system will gradually decline. This is mainly manifested in the reduction of sperm quantity and quality, as well as the change of sex hormone levels. The study found that with the growth of age, the number of male sperm will gradually decrease, and mobility and morphology will also be problematic. In addition, a decrease in testosterone levels can lead to problems such as decreased libido and erectile dysfunction.
In hospital related examinations, the commonly used indicators to evaluate male fertility include semen analysis and hormone detection. These examination results often show age-related decline in reproductive function, which affects male fertility. Therefore, the decline of reproductive system function is an important reason for the difficulty in childbearing of older men.
2. Sperm DNA damage
With the growth of age, the DNA in male sperm will also be damaged to some extent. This is mainly due to the sperm exposed to various environments and external pressures in the body. The study found that the proportion of DNA fragments in the old male sperm was high, and DNA damage would affect the fertilization ability of sperm and the normal development of embryos.
In response to this problem, some hospitals and reproductive centers have begun to apply advanced reproductive technologies, such as sperm single cell capture technology, to improve the chance of older men to conceive. By capturing sperm without DNA damage, the risk of DNA damage during fertilization can be reduced, and the quality of embryos can be improved.
3. Risk of chronic diseases caused by old age
With the growth of age, the risk of men facing chronic diseases is gradually increasing. For example, older men are more likely to suffer from diseases such as hypertension, diabetes and cardiovascular disease. These chronic diseases have a negative impact on the male reproductive system, affecting testicular function and sperm production.
In addition, some drugs that need to be taken for a long time may also have adverse effects on male fertility. For example, some antibiotics, antiviral drugs and anticancer drugs may affect sperm production and quality. Therefore, another important reason for the difficulty in childbearing of men at an advanced age is the risk of chronic diseases brought about by the advanced age.
4. Psychological pressure and lifestyle factors
The difficulty of procreation in older men is also closely related to psychological pressure and lifestyle factors. With the growth of age, the life and work pressure that men face may increase, which may lead to problems such as sexual dysfunction and loss of libido.
In addition, bad lifestyle habits will also have a negative impact on male fertility. For example, long-term smoking, excessive drinking and unhealthy eating habits may affect sperm quality and reproductive function. Therefore, psychological pressure and lifestyle factors are also the reasons for the difficulty of childbearing among the elderly men.
summary
The main causes of male reproductive difficulties at an advanced age include the decline of reproductive system function, sperm DNA damage, chronic disease risk brought by advanced age, psychological pressure and lifestyle factors. These factors have led to the reduction of the number and quality of male sperm, and affected the normal progress of fertilization and embryo development. Therefore, for men who are preparing for late childbirth, they should pay attention to the above factors and carry out relevant examinations and consultations in the hospital to improve the success rate of childbirth.
