From selecting a surrogate to a successful match, signing a contract and successfully transplanting, this process takes at least 3 months, many anxious prospective parents will have doubts, why not choose a surrogate in advance before the IVF process, and at the same time, it can save a lot of time. Here, I will explain to you why you should make a test tube first, and then match the surrogate mother after you have the result.

The first thing to understand is that although the technical level of test-tube babies in the United States is relatively high, there are still great uncertainties in the aspects of ovulation induction, egg retrieval and embryo making.

This uncertainty is reflected in two aspects.

1. Regardless of the age of the egg retrieval woman, the final result may have unsatisfactory results. The number of embryos passing through PGS is too small, or even one. I have seen a lot of expectant mothers in their twenties, who took out more than 20 eggs, and finally did not have a transplantable embryo; I have also seen experienced egg donors, and the first time they took eggs, they made 1 of them. In the blastocyst, the number of eggs taken out in the second time was similar to that in the first time, but the whole army was wiped out in the end, and there was no embryo (this situation is rare). Women in their twenties may have this situation, not to mention women in their thirties or forties.

2. There is no way to choose X sperm or Y sperm when doing ICSI. It is possible that the embryo that finally passes PGS does not have the desired sex. Perhaps some clinics will tell prospective parents that the embryologist has some experience in picking sperm, but remember that this is just experience and may be very inaccurate. In short, everything is possible before the PGS results come out. There may be an unfortunate result of no embryos, or no desired sex.

What will happen if an undesirable result really occurs, but the surrogate mother has been matched before?

1. Signed a contract with the surrogate parent company and handed over the first sum of money, which cost about 3 US dollars.

2. After finding a surrogate mother, the next step is the medical examination and legal contract, and it will cost another sum of money.

3. Usually, there will be a clause to protect the surrogate mother in the surrogacy contract. If the prospective parents do not have embryos that can be transferred within 3 months, the surrogate company or the surrogate mother has the right to release the surrogate mother for other prospective parents. To be honest, this clause is reasonable, and it should not be allowed for the surrogate to wait for the embryo of the expectant parent without restriction. Therefore, even if the prospective parents spend a lot of money, they may still not be able to retain the surrogate mother. Of course, if this happens, the surrogacy company can find another surrogate for free after the prospective parents have embryos, but how long will it take to meet the surrogate they like? No one knows that it is tethered to this surrogacy company.

4. If the surrogate mother is also willing to wait for the prospective parents to take the eggs to make embryos, then at least during this period of waiting, according to the surrogate contract, you need to pay the surrogate a few hundred dollars in monthly subsidies, or you may need to pay the surrogate mother. Medical insurance premiums of several hundred dollars per month. This money is wasted in vain, and it is more stressful to make yourself an embryo.

In short, it is safest to find a surrogate after the PGS results come out. Of course, this principle is not absolute. If the embryo is donated by an egg donor, the risk is still very low. If you encounter a preferred surrogate mother, you can also consider setting it first.
