冻卵的流程和价位是什么？
For those who are new to the concept of IVF, navigating through the various technical terms can be quite bewildering. One such individual is Ms. Zhang (pseudonym), who, along with her husband, is considering undergoing IVF in the United States. However, during her discussions with the doctor, she encountered a series of processes that left her feeling perplexed, such as "cycle initiation" and "ovulation induction."
So, what exactly does the term "cycle initiation" refer to? Essentially, it signifies the commencement of the IVF cycle. After completing the necessary IVF examinations, a series of treatment procedures, including ovulation induction, egg retrieval, fertilization, and embryo culture, can be initiated.
Today, let's delve into the specific steps involved in commencing an IVF cycle in the United States.
1. Ovulation Induction Guided by American Doctors to Initiate the Treatment Cycle
Ovulation induction, also known as ovarian stimulation, involves using medication to stimulate the ovaries and induce ovulation. Once the ovarian follicles reach a certain size, medications for ovulation induction are administered to further stimulate follicular development and ultimately induce ovulation. This process can also be conducted in the individual's home country, where American doctors will tailor personalized treatment plans based on the woman's menstrual cycle and provide FDA-approved ovulation induction medications. The administration of ovulation induction medications and monitoring of follicular development can be carried out locally.
2. Traveling to the United States for Egg Retrieval and Sperm Collection
Women are required to travel to the United States for egg retrieval, ideally within 3-7 days before the scheduled retrieval. The egg retrieval procedure is performed under anesthesia, utilizing a technique called follicular aspiration to retrieve eggs from the ovarian follicles. The procedure typically lasts about 20 minutes and is painless. It is advisable for the husband to accompany his wife to provide sperm for fertilization. If the husband is unable to accompany her, the sperm should be transported to the United States at least two weeks prior.
3. Fertilization and Screening in the United States
In the laboratory, sperm collected is processed, and fertilization is achieved by combining sperm with eggs. Subsequently, embryos are cultured in the laboratory until the blastocyst stage. In the United States, it is common to perform blastocyst transfer on the 5th day, which enhances the success rate of conception and reduces the likelihood of embryo abnormalities. Preimplantation genetic testing (PGT) is conducted to select healthy embryos, a key factor contributing to the high success rates of IVF in the United States.
4. Embryo Transfer Procedure
The embryo transfer involves placing the embryo into the uterus. If frozen embryo transfer is planned, the woman can return to her home country after egg retrieval and await the appropriate timing for transfer. Following transfer, the embryo implants in the uterus, typically occurring within 5 to 8 days after transfer. A blood test is conducted two weeks later to confirm pregnancy.
5. Progressing to the Normal Pregnancy Phase
If pregnancy is successfully achieved, subsequent steps involve routine antenatal care, similar to those for natural pregnancies. With advanced IVF technology and the expertise of specialized medical teams in the United States, successful embryo implantation is ensured.
