Not only will it affect women’s fertility, but age will also affect men’s fertility ability

In 2012, Ramjit Raghav from India was rejoicing at the age of 96. This became a global headline news at the time. At the same time, he also broke the record of the oldest father in the world. This record was that he was 94 years old at 94Hi Huan Guizi kept records.Older men are not unfamiliar with their descendants, especially in the world of celebrities. Old British singer Rodstutt became his father at the age of 66, and rock star Mickejager was 72.When he became a father in his age, he became his father again when he was 89 years old in July 2020 when he was 89 years old.

Men can continue to produce sperm from adolescence to seniority, which means that in the later years, they can still become a father. On the other hand, women’s fertility is limited.After this age, women will stop ovulation, which means that they cannot successfully conceive; now men and women have postponed fertility. The average age of women in Britain for the first time in the UK is 29 years old and male is 33 years old.

This physiological difference often trigger discussions about female biological clocks that are about to be exhausted, and men will last longer because of fertility, but the reality is far more complicated than this, and now more and more more and more are now more and more.Research evidence shows that Nanxin’s fertility ability has also been greatly affected by age.

Egg supply

With the growth of women, the number and quality of eggs in the body will decline. The number of eggs in a woman’s life has actually decided before their birth. This process is called oogenesis;In the 20th week of women’s pregnancy, there are about 6 million-7 million germ cells in the female babies in their bodies. These cells may be converted into egg cells. After that, the number of germ cells in the fetal body will be sharpIf you decrease, the remaining germ cells will develop into primary oocytes or immature egg cells.

These immature egg cells will experience some changes, and then the original follicle structure is formed. Each follicles contain a egg. These original follicles will stay at this stage until the women reach adolescence. At this timeThis; in the period of puberty, the original follicle group of the body will be activated and mature. Every month, a mature egg cells will be excreted by the female body and released into the fallopian tube; as the female age increases, the number of follicles is the number of follicles.It will continue to be reduced; those remaining immature eggs can stay in the female body for up to 50 years. During this period, egg cells will continue to accumulate chromosomal errors with the age of women’s body.The fetus suffers from the risk of diseases such as Tang’s syndrome.

This aging and continuous decline of egg cells is the reason why women’s fertility is very limited. This kind of fertility has a steeper place after 35 years of age; after the age of 35, the ovaries of the body’s ovaries areThere will be about 25,000 egg cells in the middle. By the year, about 1,000 egg cells in the body will be left.

Elderly father

Men’s fertility does not stop suddenly like women. The testicles in the body will continue to produce male hormone testosterone and fine cells, which will make men still become father in their 90s.However, this does not mean that men’s fertility ability will not be affected by age. Some studies have shown that when women are adjusted, compared with men under 30, men over 40 years of age have been in the past 12 months in the past 12 monthsThe possibility of making a partner conceive will be reduced by 30%.

Although the sperm in men will continue to occur, its quality will change, and the number of sperm generated (concentration or counting), sperm movement ability, and its shape will continue to change with the age of men.In the results of a sperm quality research on men who are aged 16.5-72.3 years old, researchers have found that before the age; But after the age of 40, the proportion of sperm concentration and normal morphological sperm will decrease. After 43 years of age, the cloud driving force of sperm will decrease, and the ejaculation will decrease after 45 years old.In a comprehensive analysis study in 2015, the researchers used data from 90 studies, and found that the age of men was directly related to the decline in the proportion of men’s total sperm count, sperm’s cloud power, and normal morphological sperm.

Researchers have also found that the elderly father is also related to the negative impact of its descendants’ health. The sperm DNA in the elderly male body will accumulate damage and mutations.Egg cells are combined with fertilization), and the descendants of the elderly father will also show high popularity of genetic abnormalities, child cancer, and various neurological diseases, such as autism, mental illness, and bipolar disorders.

Recently published in a research report in BMI magazine, researchers found that compared with young men, the descendants of 45 or more men often have premature birth, lower birth weight, and lower APGAR scores.(A score for evaluating the health status of newborns); in addition, the offspring bred by men over 55 years of age is more likely to need to perform auxiliary ventilation operations or enter the newborn ICU.On average, women’s fertility windows are much shorter than men can produce sperm, but the negative impact of age on women’s fertility is evidence to follow; now more and more research evidence shows that the elderly are the elderly.Sperm quality in men’s body is often poor, and the incidence of sperm damage and mutations will increase. Therefore, elderly men will also need to consult the risks of their future generations in the future.
