1. The change in the concept of childbearing among school-age women

.

Because, there may be no plans to get married and have children in the short term. There are also some women who have not made specific plans for the birth of a new life after marriage.

2. Choices in freezing technology

In the field of freezing technology, there are two different methods: "freezing eggs" and "freezing embryos". So, what are the differences between frozen eggs and frozen embryos? For women in need

How to make a choice based on your actual situation?

(1) What are frozen eggs?

Frozen eggs, also known as frozen eggs, refers to the promotion of ovulation under the guidance of a doctor when the mother is in a healthy state (generally recommended age is 25 - 35 years old), and then freezing the eggs to avoid

The quality of immunized eggs decreases as the human body ages. When there is a need for fertility, frozen eggs are thawed and used. According to reproductive experts, as women age, the pregnancy rate will gradually

At this time, the egg is in a dormant state and will not continue to grow and develop, nor will it age with the passage of time, nor will it affect its genetic material. Moreover, the egg recovery rate is as high as 90

% above. Women can freeze their eggs for 1, 5, 10 years or even longer according to their own needs. After thawing, their vitality and health are no different from fresh eggs.

It should be noted that the older a woman gets, the ovarian function will gradually decline, and the quality and number of eggs will decrease significantly. It would be of little significance if the eggs in question were cryopreserved. Therefore

It is recommended that women freeze their eggs before the age of 38 and cryopreserve eggs with good quality and high maturity.

(2) What are frozen embryos?

Freezing embryos is a very mature method of preserving fertility. For young couples who have no family plans for the time being, as well as concerns that egg quality will decrease with age and fear of missing the golden childbearing age

Families (23 - 30 years old) can perform the first half of the cycle through IVF, that is, after ovulation promotion, egg retrieval/sperm retrieval, sperm-egg combination, blastocyst cultivation, and genetic testing, the results will be obtained.

Kang blastocysts are cryopreserved. Wait until you really have the intention to have children, you can directly thaw and transplant it.

IVF embryos are frozen in liquid nitrogen environment at minus 196 ° C. In this environment, the growth of the embryo stops, the activity of the enzyme is completely inhibited, and the cells are in a metabolic standstill.

Therefore, freezing embryos will not affect the quality of the fetus or the health of the baby.

The advantages of this method are mainly reflected in two aspects: first, it better preserves the fertility of the couple; second, based on the mature application of this technology, experts can create a good uterus for the blastocyst

Internal Environment

For example, before transplantation, experts will first pass relevant examinations to check the internal environment of the uterus (whether the thickness of the endometrium is up to standard, whether there is inflammation/disease or malformation, etc.) and the hormone level in the woman's body.

No the migration requirements were met. For women who are not suitable for immediate transplantation, the blastocysts will continue to be cryopreserved first, and they will be conditioned or diagnosed with symptomatic symptoms. After your body recovers, choose the right time to defrost

Implant

From the above explanation, it can be seen that there is a big difference between an egg and an embryo. An embryo is formed by the combination of an egg and sperm, and the egg is just a germ cell. Relatively speaking, it has higher requirements on the external environment

Embryo contains multiple cells and is much more adaptable to the outside world than egg cells. As a result, married women often prefer frozen embryos because they are easier to survive.

(3) Populations suitable for frozen eggs and frozen embryos

Frozen eggs are suitable for unmarried women

Fertility is free, and women have the right to decide when to give birth. For women, the quality and quantity of eggs decline after the age of 35. Faced with the dual pressure of urging marriage and promoting birth, frozen eggs can allow women to have

The right to choose is like having the "regret medicine" of life, not bound by time.

In modern society, many well-educated women have certain cognitive and self-improvement abilities. Many of them are still single because they want to find someone who is compatible and suitable to have children with.

people, but it also takes a lot of time to plan. Egg freezing has given these single women hope that they can "freeze" their time.

Secondly, for women who may have lost ovarian function, if they suffer from cancer and need chemotherapy, radiation treatment or removal of ovarian diseased tissue, eggs can be frozen in advance to preserve fertility.

Frozen embryos are suitable for married women

If you are a young couple who have no family planning for the time being and are worried that the quality of the eggs will continue to decline with age, you can complete the golden reproductive period through IVF. After the first half cycle, P

Healthy blastocysts after GS/PGD gene testing are frozen and can be directly thawed and transplanted when they want to have children. Couples with a second child plan can directly use the remaining health benefits from the first IVF.

embryo.

Women who cannot be transplanted temporarily during the test tube cycle: Good physical condition of a woman is one of the key factors for the success of embryo transfer, including normal female body, good intrauterine environment and stable endocrine level. Only when the level is stable can you enter.

Perform embryo transfer. Therefore, general IVF clinics will freeze the embryos and transfer them when the expectant mother's uterus is in good condition.

Whether you choose to freeze eggs or frozen embryos, women should be reminded to freeze in advance at an appropriate age. Because the quality of women's eggs will decline with age, the older they get, the gain will be

The fewer mature eggs will be obtained, and the fewer embryos will be obtained after fertilization. Correspondingly, the success rate of thawing will also change. Therefore, freezing eggs and embryos needs to be done early!
