With the increasing popularity of the country's policy of fully opening up two children and three children, the history of only having one good child has come to an end. This policy is undoubtedly a timely help to families born in the 1970s who have dreams of having children and are at the tail end of the optimal childbearing age, and many families have the opportunity to change their lonely and elderly fate.

The idea of having another child is a normal appeal for families who have lost independence. The editor of 592 Baobao Network believes that as long as the conditions are suitable, families with lost children can also consider having another child, because a newborn can bring new hope to the family. However, there are certain advantages and disadvantages to having offspring in vitro at an advanced age, and it is necessary to consider carefully before making a decision.

Having a new child in a lost family can alleviate the pain of losing a child for both spouses and reignite hope in their lives. After giving birth to their daughter Lili through in vitro fertilization (IVF) technology, the Du family, born in the 1970s, felt various pressures and inconveniences in parenting. However, the joy and laughter brought by the birth of their daughter restored vitality to their once stagnant home, and the couple felt that all the expenses were worth it.

50 years old is no longer a suitable age for childbirth, and the age of the female partner has a significant impact on the success rate of IVF. When promoting ovulation, the physical response of elderly women is usually very poor, the quality of eggs is relatively poor, and the pregnancy rate is also lower. It is not easy to succeed in IVF. Research data shows that for women aged 25 to 35, the success rate of in vitro fertilization is higher than the average level of 30% -40%, with some reaching 50% or even higher; But after the age of 35, the success rate gradually decreases, and by the age of 40, it is only about 20%. It can be seen how low the success rate of a 50 year old woman undergoing in vitro fertilization is, and it is likely that she spent a lot of money but got lost.

IVF is an assisted reproductive technology for infertile women. Although this advanced technology can bring good news to infertile women, it is not a pregnancy method for elderly pregnant women. Epidemiological experts from the Centers for Disease Control and Prevention in the United States report that the likelihood of congenital defects in IVF is 2– 4x. The probability of spontaneous abortion is also high, and pregnancy complications are also quite high. So it is very difficult for families who are 50 years old and have lost children to have in vitro fertilization (IVF). They need to have sufficient financial ability and good luck to have another child.

The editor of 592 Baobao website learned that China adds 76000 new families each year, with over a million families lost in the country. Demographers further infer from census data that out of China's 218 million only children, 10.9 million may die before the age of 25, and over 10 million families may become "lost only families". From this, it can be seen that having a new child will be the choice for the vast majority of families with lost children.
