Whether to have children or not has become a classic dilemma for parents-to-be, and in order to fulfill their career aspirations and provide the best environment for their children to grow up, birth plans are then moved back. In fact, there are many disadvantages to having children too early or too late. Studies have shown that the best age for women to have children is 24-29 years old and the best age for men to have children is 27-35 years old. The best age for women to get pregnant In the period of 23-30 weeks, the female body is fully developed and mature, the quality of eggs is high, if you are pregnant with a child, the risk of childbirth is small, the fetal growth and development is good, the incidence of premature birth, deformities and dementia is the lowest; if you get pregnant earlier than 20 years old, the fetus and the developing mother compete for nutrients, which is not good for the mother’s health and fetal development. As we age, follicles accumulate in the ovaries for too long, causing chromosomes to age and decline. The older you get, the more chance there is for mutations to occur in the genetic material, leading to congenital dysmorphism and various malformations. In addition, the probability of pregnancy decreases with age, making it more likely that pregnancy complications will occur. The best age for men to have children When considering the age of women to have children, the age of men to have children should not be ignored. Studies have shown that the best age for men to have children is 27-35 years old, because the quality of male sperm reaches its peak during this period, and men at this age are not burdened with intellectual maturity, have more life experience, and are able to understand and accept the knowledge of fetal education. In particular, they will care for and love their wives and have the ability to nurture their babies and children well, thus enabling good fetal growth and development. After the age of 35, the androgen in the body also begins to decay, and the secretion of testosterone decreases by 1% every year on average. When men are too old, the genetic mutation rate of sperm increases accordingly, and the quantity and quality of sperm are not guaranteed, which is also detrimental to the health of the fetus. The best season for conception Choosing the right season for pregnancy is not only good for the baby’s early development, but also has a great impact on the care of the newborn and the recovery of the mother’s body. There are four seasons in a year: spring, summer, autumn and winter. If the mother-to-be chooses to conceive between early July and early September, then congratulations, you have taken a crucial step towards a better pregnancy. It is most suitable to conceive from early July to early September because the early pregnancy reaction is in autumn, which avoids the influence of summer on appetite, and there are abundant varieties of fruits and vegetables in late summer and early autumn, which are fresh and delicious, and the mother-to-be’s early pregnancy symptoms basically disappear and her appetite increases at this time, so she can plan to provide sufficient nutrition for mother and child. Indoor and outdoor air pollution has a significant impact on embryonic teratogenesis in early pregnancy. In winter, the highest concentration of sulfur dioxide and total suspended particulates in the atmosphere, the birth defect rate of 7.8% o, the lowest concentration in summer and autumn, the birth trap rate of 5-5.8 ‰. July-August conception, but also make the most sensitive and delicate early pregnancy to avoid the cold and pollution more serious winter, and the next year in early spring with rash, influenza and other viruses, the pregnancy has reached the middle of the fetus has safely passed the teratogenic sensitive period. When spring is in full bloom, the fetus is maturing, and the good weather conditions and beautiful nature provide a worrying external environment for the implementation of fetal education. After the October pregnancy, the baby is born in the late spring and early summer when the wind and sun are warm and the climate is suitable, so it is easier to take care of the baby, and the baby is not easy to get cold in the bath, and can go outside to breathe fresh air and get more sunshine, which is also very beneficial to the new mother’s body recovery. The best time to conceive A woman has six days a month as the best time to conceive, namely five days before ovulation and the day of ovulation, and it is most appropriate to conceive at 9-10 pm. The physiological phenomena and functional states of the human body are constantly changing throughout the 24 hours of the day. The functional state of the human body tends to rise from 7 a.m. to 12 p.m. The lowest point in the day is from 13 to 14 p.m., and then rises again at 5 p.m. After 1 p.m., it falls sharply. Generally speaking, 9-10 p.m. is the best time to have intercourse for conception. After having intercourse at this time, the woman sleeps flat for a long time to help the sperm swim and increase the chances of contact and encounter with the egg.
