From a technical standpoint, assisted reproduction is divided into traditional IVF techniques and non-traditional IVF techniques. The traditional IVF technique is still the mainstream, and this technique is heavily medicated and aimed at fresh transplants. If mastered well and selected patients with good prognosis are done, the pregnancy rate of fresh transplantation can reach about 50% or even 60%. There are many disadvantages of traditional IVF technique: 1) long-term, repeated and large amount of drug injections; 2) expensive; 3) only suitable for patients with good ovarian function, not for patients with low ovarian reserve; 4) 4-7% incidence of ovarian hyperstimulation, which can be life-threatening in serious cases. Non-traditional IVF technology is a new technology developed in the last decade. The most important feature is that it aims to freeze the transplantation and does not use the traditional descending superovulation technique. These techniques are suitable for both patients with good and poor ovarian function, and are much more capable of solving difficult patients than traditional IVF techniques. Ovulation boosting injections are shorter, less expensive, have fewer complications, almost no ovarian hyperstimulation and a much lower incidence of ectopic pregnancy. The success rate is higher than traditional IVF techniques when a comparison is made based on the same patient conditions. Embryo transfer is performed in a natural cycle where the fetus is conceived in a physiological hormonal environment, consistent with nature, with fewer complications during pregnancy. Non-traditional IVF is in the hands of only a few centers at the moment and the technology is not widespread; the fact that the transfer cannot take place immediately after egg retrieval and the frozen transfer has to be done separately may be its disadvantage. However, we have also done calculations, non-traditional IVF technology does not use descending regulation and does not require frequent monitoring of the effect of descending regulation and ovulation promotion response, so the total number of patient visits to the hospital is reduced.
