frequently asked questions
Visa section
There are two ways: tourist visa and medical visa. At present, 80% of our guests are mainly tourist visas and 20% are medical visas. Generally, it is recommended that guests apply for tourist visas. The pass rate of tourist visas is higher than that of medical visas, but it is not sure that they can pass 100%. When applying for a visa, HRC can provide an invitation letter and medical certificate if the guest needs it, but the guest needs to pay a certain medical fee (about 10,000 US dollars) first, and establish a file and medical treatment plan in the hospital system.
The general possibility of visa refusal is very small, unless there is a bad exit record, there is a tendency to immigrate, or the information is not fully prepared.
If a tourist visa has been rejected, it is generally necessary to wait for a while before applying again. For details, you can also consult a visa specialist and analyze the situation according to different circumstances.
Likely, but not 100%, if there is a real need for fertility treatment,
In the case of complete information and sufficient assets, the visa will generally not be rejected.
There was no record of going to the United States to have a child at the customs level, and it had no impact on the visa. Guests only needed to prove that going to the United States to have a child would not cost the United States, and they had enough cash and assets to prepare for it, and there would be no problem in this regard.
Fertility preservation section
Fertility and Sterility, an authoritative journal in the field of reproductive medicine, found that the average age of fertility preservation guests is 34, but many women also perform fertility preservation around the age of 40. The so-called "age limit" varies from individual to individual, mainly based on the guest's ovarian function and egg quality. Generally speaking, ovarian function and egg quality decrease with age, and the recovery rate after fertility preservation and the live birth rate of embryos will decrease accordingly.
The 2013 Fertility and Sterility article analyzed the pregnancy success rate after fertility preservation and resuscitation between January 1996 and June 2011, and found that the live birth rate decreased from 31.5% at age 25 to 14.8% at age 40, depending on the age at which women's fertility was preserved. For this reason, we encourage you to choose fertility preservation as soon as possible to continue your fertility.
In theory, eggs can be stored permanently in liquid nitrogen at -196 degrees Celsius. After vitrification, the metabolism of internal cells in eggs is reduced, and germ cells will be temporarily out of the growth state. According to the supplement of "Fertility and Sterility" in 2010, eggs, embryos and fresh eggs after thawing and resuscitation showed no difference in clinical pregnancy, and fertility preservation has become the best way to delay fertility. However, in view of the physical function of women conceiving and the fertility risk of advanced maternal age, we recommend that fertility preservation be maintained for about 10 years.
A normal woman will release a fixed number of 400 mature eggs during her reproductive period, so many women believe that drug ovulation is "premature overdraft" of future eggs, which will lead to premature ovarian failure. In fact, this is a misunderstanding. Normal women will have multiple follicles develop at the same time in each menstrual cycle, and finally only 1-2 follicles develop into high-quality follicles, and the rest enter the atresia period and gradually decline. Drug stimulation is to stimulate the growth of follicles that were originally about to enter the atresia period and use them. Therefore, there is no such thing as "premature overdraft" of eggs, so ovulation stimulation will not lead to premature ovarian failure.
促排、取卵具有个体差异。如果卵巢功能良好，卵子优质可以一次获得足够数量的卵子，但如果卵巢功能不好，卵子数量和质量都不高的话，则需要多次取卵。根据2016年《生育与不孕》一项基于1850名25至42岁生育力保存女性与卵子解冻复苏、活产率的研究，建议25至30岁的女性生育力保存12-18颗，30岁至35岁女性生育力保存18-20颗，35岁至40岁女性20-24颗，40岁以上女性30颗，可保证未来卵子解冻复苏、活产率在80%左右。
test tube part
IVF mainly includes 5 periods: preparation period: 1-2 months; down-regulation period: 7-21 days; ovulation promotion period: about 14 days; transplantation period: 30 days; pregnancy test period: (12 days after transplantation).
This depends on the project carried out by the guest. The self-fertilization project requires two trips to the United States. The first trip to the United States for an egg retrieval cycle takes about 14 days, and the second trip to the United States for a transplant cycle takes about 30 days.
Egg retrieval does not cause premature ovarian failure. Artificial ovulation stimulation is to stimulate the eggs of a woman's menstrual cycle to grow with drugs, not "advance" future eggs. During a woman's natural cycle, 1-2 eggs will naturally grow and be discharged in a menstrual cycle, and the rest will enter the atresia period and then die. Artificial ovulation stimulation only uses these eggs that would otherwise die, so it is not "advance" eggs, and it will not cause premature ovarian failure.
Sperm and egg quality is one of the important factors affecting the success rate of IVF. For men, the sperm fragment rate index (DFI) is usually between 10% and 20%. If it exceeds 20%, it has an impact on conceiving a healthy baby. The so-called sperm fragment is affected by certain factors (such as smoking, staying up late, radiation, drugs) during the formation process, and the integrity of sperm DNA is damaged to produce broken fragments. Men can improve by quitting smoking, drinking, and adjusting their lifestyle. At the same time, they can take care products. For women, the quality of eggs is closely related to age and ovarian function.
Women can adjust by increasing the proportion of antioxidant foods in their diet while taking coenzyme Q10 and multivitamins.
After the egg and sperm combine to form a fertilized egg, cells continue to divide, forming a blastocyst (Morula) composed of 8-12 blastocysts on the 3rd day, and a blastocyst (Blastula) composed of 100 + cells on the 5th day. Therefore, fresh embryos are generally divided into blastocysts and blastocysts. Relatively speaking, embryo freezing is frozen embryo. Current clinical data show that the pregnancy rate of blastocysts in the cycle is due to blastocysts, especially after pre-implantation genetic screening and diagnosis (PGS/PGD).
However, the pregnancy rates of fresh embryos and frozen embryos are slightly different, and the choice of which transfer is mainly based on the quality of the embryo itself and the female uterine environment.
