Causes of infertility in the elderly
Elderly childbearing infertility refers to the situation that it is difficult for women to conceive naturally or miscarry when they are older. With the development of society and the change of people's ideas, more and more women choose to postpone childbearing, which also leads to the increase of infertility in the elderly. The causes of infertility in the elderly can be explained from four aspects: physiological, psychological, environmental and genetic factors.
Physiological factors
1. Egg quality decline: With the increase of age, the quality of female eggs gradually declines. This is because the number of female eggs is fixed at birth. With the growth of age, the quality of eggs begins to be damaged, and it is difficult to fertilize and develop normally.
2. Dysfunction of uterus: With the increase of age, the endometrial thickness and blood flow of female uterus decrease, which will affect the implantation of fertilized eggs and the development of embryos.
3. Decreased hormone secretion: after menopause, women's ovarian function begins to decline, follicular development decreases, and hormone secretion decreases, which will lead to ovulation dysfunction, thus increasing the risk of infertility.
psychological factor
1. Impact of pressure: As people grow older, they begin to doubt and pressure women's fertility. This kind of pressure will lead to women's anxiety and tension, which will have a negative impact on fertility.
2. Anxiety: The growth of age will also make women anxious about childbirth, and worry that they will not be able to successfully conceive or have a healthy baby. This anxiety will interfere with the normal development of eggs and the environment of the uterus.
3. Psychological pressure: The infertility problem of elderly childbearing will bring strong psychological pressure to women, which may lead to psychological problems such as depression and emotional runaway, and further affect fertility.
environmental factor
1. Bad living habits: bad living habits include smoking, drinking, irregular diet, etc. These bad habits will damage the female reproductive system and increase the risk of infertility.
2. High work pressure: In modern society, the work pressure is high, and the tense work rhythm and long work lead to women's lack of time for rest and relaxation, which will have a negative impact on fertility.
3. Environmental pollution: pollutants in the environment will have negative effects on the female reproductive system, such as air pollution, water pollution and chemical exposure, which will increase the risk of infertility.
Genetic factor
1. Genetic diseases: some genetic diseases, such as polycystic ovary syndrome and genetic chromosomal abnormalities, will affect women's reproductive ability and increase the possibility of infertility.
2. Family history: direct relatives with infertility history, such as mothers or sisters with infertility symptoms, will increase the risk of female genetic infertility.
3. Mutated genes: Mutated genes held by women will increase the possibility of fertility problems. For example, BRCA1 and BRCA2 gene mutations are related to ovarian and breast cancer, and have a certain relationship with fertility decline.
Summary
The causes of infertility in the elderly can be summarized into four aspects: physiological, psychological, environmental and genetic factors. Physiologically, with the growth of age, the quality of eggs declines, uterine function declines, hormone secretion decreases and other factors lead to infertility. Psychologically, the increase of stress, anxiety and psychological pressure affects fertility. In terms of environment, bad living habits, high work pressure and environmental pollution will increase the risk of infertility. Heredity, genetic diseases, family history and mutant genes will affect fertility. Therefore, women who want to delay childbirth, especially older women, should actively take measures to reduce the risk of infertility, such as regular physical examination, improving lifestyle, relieving stress, etc.
