At what age do men tend to have older children?

More and more couples have late marriage and late childbearing, leading to the problem of elderly childbearing gradually attracted people's attention. Although female reproductive capacity will decline significantly with age, male age is also important for fertility. The problem of elderly male fertility is determined by many factors. The following will be a detailed analysis from four aspects: reproductive hormone level, sperm quality, genetic problems and reproductive health risks.

Reproductive hormone level

Reproductive hormones play an important role in male fertility. However, with the increase of age, the level of male reproductive hormone gradually decreases. A study shows that testosterone levels in men over 40 decline faster than those in young men. This may lead to the reduction of sperm quality and quantity, thus affecting fertility. Therefore, men over the age of 40 are prone to elderly fertility problems.

In addition, unlike women, the decline of male reproductive hormone levels is relatively slow. This means that men can still maintain a certain fertility after they are old, but with the growth of age, the probability of successful pregnancy will decline significantly.

Sperm quality

Sperm quality is critical to male fertility. However, with age, the quality of male sperm will also be affected. The study found that the sperm morphology and vitality of men over 40 years old declined faster, while environmental pollutants such as particulates and heavy metals further aggravated this problem.

The decrease of sperm quality will directly affect the success rate of pregnancy, and increase the risk of abortion, embryo malformation and child development problems. Therefore, after the age of 40, the decline of sperm quality may become the main obstacle to the elderly childbearing.

Genetic problems

Older men may also face a series of genetic problems. Research shows that there is a correlation between the father's age and the risk of chromosomal abnormalities, low birth weight, autism and mental illness.

Male sperm is a kind of cell, which will also mutate with age, which may lead to chromosome abnormalities or gene mutations in children. Therefore, men who choose to give birth at a higher age should fully understand the genetic risks, consult professional doctors, and carry out relevant genetic counseling and testing.

Reproductive health risks

Older men also face reproductive health risks. The risk of men suffering from prostate diseases, sexual dysfunction and reproductive system diseases increases with age.

For example, the incidence of BPH and prostate cancer is closely related to age. These diseases can affect male fertility and even lead to infertility. In addition, aging also increases the risk of men suffering from sexual dysfunction, such as erectile dysfunction and ejaculatory dysfunction.

summary

The reproductive problems of older men are mainly affected by reproductive hormone levels, sperm quality, genetic problems and reproductive health risks. Men over 40 years old are facing the problem of declining fertility. The reduction of sperm quality and quantity may lead to fertility problems in the elderly. In addition, when giving birth at an advanced age, men also need to pay attention to genetic risks and reproductive health risks. Therefore, both husband and wife should fully understand the problem of male elderly childbearing and consult professional doctors when necessary.
