Description of IVF cycle
Test tube baby is a kind of assisted reproductive technology, which is widely used in infertile couples. The length of IVF cycle is affected by many factors, including individual differences, hospital size, medical technology and treatment plan. This article will introduce the time of IVF cycle from four aspects.
Preliminary screening and preparation stage of the hospital
The IVF cycle usually starts from the initial screening and preparation stages. Couples need to seek the help of professional doctors and have a comprehensive physical examination to understand the causes of infertility. Doctors may conduct semen analysis, women's oviduct patency inspection, etc., to develop personalized treatment programs. This stage can last for several weeks to several months, depending on the hospital and individual conditions.
In the hospital preparation stage, women may need to conduct ovulation guidance to urge the ovary to release more eggs. This can be achieved through drugs or injection of ovulatory hormone. The ovulation induction period usually lasts 10 to 14 days, during which the doctor will conduct regular examinations to monitor the growth of follicles and the thickness of endometrium.
The whole initial screening and preparation period is usually 2 to 3 months, which is an important step to ensure the success of IVF.
Egg collection and fertilization
Egg collection is one of the core links of IVF cycle. When it is determined that the egg is mature, the doctor will perform an egg collection operation. This process is usually carried out under local anesthesia, and doctors will use ultrasound guidance to locate and puncture the ovary. The egg is drawn through a fine needle and sent to the laboratory for fertilization.
Fertilization process is usually divided into traditional IVF and micro incubation IVF. In traditional IVF, sperm and egg are cultured together to wait for fertilization. Microincubation in vitro fertilization is to inject a single sperm into the egg to increase the success rate of fertilization. This process is usually completed within 24 hours after egg collection.
Embryo culture and transfer
The fertilized eggs are cultured in the laboratory, usually lasting 3 to 5 days. During this period, doctors will select the embryo most likely to be implanted successfully according to the quality and development of the embryo.
Embryo transfer is the last step in the IVF cycle. Doctors use catheters to transfer embryos into a woman's endometrium. This process is usually simple and painless and does not require anesthesia. The whole process of embryo transfer only takes a few minutes, and women can return home to rest after completion.
Waiting and pregnancy results
After IVF transplantation, couples need to wait for pregnancy results. During the waiting period, women usually continue to take progesterone and other hormone drugs to help embryo implantation and maintain early pregnancy.
The waiting time for pregnancy results is usually 10 to 14 days, during which the doctor may recommend a blood test or an early pregnancy ultrasound to confirm the success of the pregnancy.
summary
The time of IVF cycle is not fixed and varies according to individual differences and treatment plans. The initial screening and preparation stage in the hospital usually lasts for several months. The egg collection and fertilization process is completed within 24 hours. Embryo culture takes about 3-5 days, while embryo transfer and waiting for pregnancy results usually take 10-14 days. By understanding the different stages of the IVF cycle, couples can better understand the whole process and be prepared psychologically and physically.
