Calculation method of pregnancy cycle of test tube baby
IVF is a kind of assisted reproductive technology, which aims to help couples who cannot conceive naturally realize their reproductive aspirations. The success rate of IVF is closely related to the reasonable arrangement of pregnancy cycle. The calculation method of IVF pregnancy cycle will be described in detail from four aspects.
1. Personal health assessment
Before starting the IVF program, a personal health assessment is required. This includes physical examination and relevant medical history records of both spouses. Doctors will evaluate the quality of women's uterus, ovaries and men's sperm to determine whether it is suitable for IVF.
First, women need to have an endoscopic examination of the uterus and ovaries. This can help doctors evaluate the shape and structure of the uterus and whether there is abnormal follicular development in the ovary. For men, sperm quality is also an important factor. The doctor will ask the man to conduct semen analysis to assess the number, vitality and morphology of sperm.
Personal health assessment is the prerequisite for the success of IVF, which can ensure that the physical conditions of both parties meet the requirements of IVF and provide guidance for subsequent treatment plans.
2. Monitoring and regulation during ovulation
The success rate of IVF is related to women's ovarian function and ovulation cycle. Therefore, the monitoring and regulation of ovulation is a very important step in the calculation of IVF pregnancy cycle.
Generally speaking, ovulation monitoring will include blood tests and ultrasonic tests. Blood examination can monitor the levels of luteinizing hormone, estrogen, follicle stimulating hormone and other hormones to determine ovarian function and ovulation time. Ultrasonic examination can observe the development of follicles and determine the best time for fertilization.
If a woman's ovarian function is abnormal, the doctor may recommend drug regulation to promote follicular development and ovulation. Drugs can improve the success rate of IVF by promoting follicular growth and ovulation.
3. Fertilization and embryo transfer
Fertilization and embryo transfer are key steps in IVF pregnancy cycle. Artificial insemination or egg taking is carried out within 24-36 hours after ovulation of the female, and the male sperm is combined with the female egg to form a fertilized egg.
Generally, the fertilized egg after fertilization will continue to develop in the culture dish. Doctors will decide the best time for embryo transfer according to the quality and development of the embryo. During embryo transfer, doctors will place the embryo into the female uterus through patient and careful operation to increase the chances of embryo implantation.
The success rate of fertilization and embryo transfer depends on many factors, including the quality of the embryo, the state of the female uterus, etc. Doctors will adjust and guide according to the actual situation to improve the success rate of transplantation.
4. Rest and observation
After IVF embryo transfer, it is usually necessary to rest and observe. During the rest period, women need to follow the doctor's advice to avoid strenuous exercise and stressful work. Doctors may recommend progesterone support treatment for women to increase the probability of embryo implantation.
After embryo transfer, women usually need to wait about two weeks before they can conduct a pregnancy test. During this period, doctors will conduct regular blood tests and ultrasonic tests to see whether the embryo is successfully implanted.
After the rest and observation period, the doctor will check whether the embryo is successfully implanted and determine whether it is successfully pregnant.
Summary
The calculation methods of IVF pregnancy cycle mainly include personal health assessment, ovulation monitoring and regulation, fertilization and embryo transfer, rest and observation. Through the reasonable arrangement and monitoring of the above aspects, the success rate of IVF and the reproductive opportunities of pregnant women can be improved. However, the situation of each couple is different, so it is recommended to consult a professional doctor before formally carrying out the IVF program to obtain personalized treatment plans and guidance. Only when the pregnancy cycle is calculated and arranged reasonably and scientifically can couples welcome their babies as soon as possible.
