Nowadays, many infertility patients hold the idea that “there is no hurry, if it doesn’t work, they will go for ‘IVF’ treatment”. However, I would like to remind you that it is better to treat infertility early than late. Couples who have a regular sex life and have not used contraception and have not conceived for more than 1 year need to be seen by a hospital to check the cause of infertility and treat it early. With the development of society, modern couples are planning for fertility later and later. However, age is an important factor that affects fertility. The best age for women to have children is 25-29 years old. After 30 years old, women’s fertility starts to decline, and after 35 years old, fertility declines steeply, while after 40 years old, women gradually enter the perimenopausal stage, and there are few successful pregnancies. As the age of consultation increases, the pregnancy rate after treatment gradually decreases, and for women over 35 years old, the pregnancy rate after treatment is relatively low. Therefore, it is best to seek treatment for infertility before the age of 35. Even in IVF treatment, we have found that younger women, with better ovarian function and sensitivity to drugs, can obtain more eggs and have better egg quality and embryo formation, and have a better chance of successful pregnancy. However, younger women should not neglect to take this lightly and should pay attention to the age of their ovaries. In some women, although they are very young, the ovaries have already started to decay, and in their 20s they are already as old as 40 years old and nearly menopausal, which makes it more difficult to treat such infertility patients. In addition, the chance of pregnancy is higher within the first year of consultation, and the pregnancy rate is highest in the first year of treatment, about 65%, compared with different years of treatment in the same age group, and decreases year by year in subsequent treatments. Therefore, treatment of infertility should be taken as soon as possible and should not be delayed. As age increases, not only the fertility decreases, but also the chromosomal abnormalities of embryos increase, and the spontaneous abortion rate gradually rises. The miscarriage rate is 14% at the age of 25, but rises to 44.5% when older than 35, and up to 50% for women at the age of 45. The likelihood of oocyte malformations increases with age, especially after the age of 35, and the incidence of fetal malformations increases. Studies have shown that the incidence of congenital infants is only 1/1500 in women aged 25-29, 1/900 in women aged 30-34, 1/300 in women aged 35-39, and 1/40 in women aged 45 and older. for men, age is also closely related to sperm quality and the health of the infant. sperm quality is best in men aged 25-35 and gradually declines after age 40. The quality of sperm decreases after the age of 40. There is an increase in chromosomal disorders in men with increasing age, and if the father is over 40 years old, the number of children with malformations increases by a factor of 1. The age of the couple is closely related to fertility and the health of the offspring. If the problem of infertility is detected, seize the opportunity to treat it early, so as not to miss the good time of infertility.
