Time required for second-generation IVF
IVF is an assisted reproductive technology, also known as "in vitro fertilization embryo transfer" (IVF-ET). As an improvement of IVF technology, the second generation IVF provides hope for couples who cannot conceive naturally. The time required for the second-generation IVF will be described in detail from four aspects.
preparation in advance
Before the second generation of IVF, couples need to undergo a series of medical examinations to determine whether IVF technology is suitable. These examinations include male semen analysis, female gynecological examination, reproductive hormone examination, etc. In addition, social counseling and psychological assessment are also needed to ensure that couples have the economic, psychological and social conditions to assume the responsibility of raising children.
Normally, this preliminary preparation phase will last about one month. During this period, couples need to communicate with doctors face to face, understand the whole process of second-generation IVF, and determine specific treatment plans.
Ovulation induction stage
Ovulation induction is the first step in the treatment of second-generation IVF. At this stage, women need hormone therapy to promote follicular development and ovulation. Generally, the treatment period is 10-14 days.
In this process, women need to regularly go to the hospital for ultrasonic examination to monitor the growth of follicles. Generally speaking, in the last few days before ovulation, doctors will decide the best time to conduct follicle puncture and collect mature eggs according to the ultrasonic results and blood examination results.
IVF cycle
IVF cycle refers to the process of combining female fertilized eggs with male sperm in the laboratory and cultivating them, obtaining embryos and then transplanting them into female uterus.
Generally speaking, the IVF cycle lasts 3-5 weeks. In this process, doctors will choose the best fertilization method according to the quality and quantity of female eggs. After fertilization, the embryos will be cultured in the laboratory for 2-5 days, and then the best embryos will be selected and transferred back to the female uterus.
Embryo transfer is a simple non-surgical procedure, usually without anesthesia. After transplantation, women need to rest for a period of time to promote embryo implantation. After embryo implantation, women need to continue taking hormone drugs to help the development of the embryo.
Waiting for pregnancy
After embryo transfer, couples need to wait about 2 weeks for observation during pregnancy. In the process of waiting for pregnancy, women need to continue taking hormone drugs, and regularly test the level of progesterone in blood and urine.
After waiting for the end of the pregnancy period, the couple can carry out maternal ultrasound examination to determine whether the pregnancy is successful. If the pregnancy is successful, women need to continue to receive prenatal examination and pregnancy health care to ensure the normal development of the embryo and the health of the mother.
Summary
The time required for the second generation of IVF mainly includes the preliminary preparation, ovulation induction stage, IVF cycle and waiting period for pregnancy. The whole treatment process takes about 2 months. In this process, couples need to visit the hospital regularly and follow the doctor's advice. Although there may be some discomfort and risks during the treatment, the second-generation IVF technology is a promising choice for couples who cannot conceive naturally.
