Time cycle of IVF
In vitro fertilization (IVF) is an assisted reproductive technology that combines eggs and sperm in vitro, and then implants the fertilized eggs into the female uterus to help couples who cannot conceive naturally achieve their reproductive aspirations. The time cycle of IVF varies with individual circumstances.
The first stage is the oocyte retrieval stage, which determines the development and castration function of oocytes through tubal ultrasound and blood examination. Then, increase the injection of ovulation drugs through daily injection to stimulate the maturation and development of follicles. Generally, this stage lasts about 10-14 days.
The next stage is the sperm extraction stage. On the same day after the eggs were taken, the man provided sperm samples and needed to complete the semen treatment process in a specific room. This process usually takes 30 minutes to 1 hour. In some cases, if the man has sperm problems, he may need to obtain sperm through sperm retrieval and other technologies.
Then there is in vitro fertilization and embryo culture. In this stage, the ovulated egg is combined with sperm to make it naturally pregnant. The combined egg and sperm will be placed in the artificial medium and cultured until the embryo develops to the appropriate stage. This process usually takes 2-6 days.
Number of IVF attempts
The success rate of IVF is closely related to the number of attempts. According to the data of many fertility centers in the world, the success rate of IVF is usually between 30% and 40%. Therefore, multiple attempts can improve the chances of fertility success.
In many hospitals at home and abroad, couples are usually advised to try 2-3 times after the first attempt fails. If repeated attempts still fail, doctors may conduct a comprehensive assessment of personal conditions and provide more accurate treatment plans to improve the success rate.
However, not all couples need to try many times. Some couples may become pregnant on their first attempt. Therefore, the situation of each husband and wife is different, and the number of attempts needs to be determined according to the individual situation.
Factors related to the success of IVF
The success of IVF is related to several factors. This includes the age of the woman, the quality of eggs and sperm, the health of endometrium, and the quality of preimplantation embryos.
The age of the woman is a very important factor. The older the woman, the lower her fertility. Therefore, older women may need to try many times to get pregnant successfully.
In addition, the quality of eggs and sperm is also the key to the success of IVF. If the quality of eggs and sperm is low, the success rate of fertilization and embryo development will also be reduced.
The health of the endometrium can also affect the results of IVF. If the endometrium is too thin or there are other abnormalities, the success rate of embryo implantation will also decline.
summary
The time cycle of IVF varies from person to person, usually including the stages of egg retrieval, sperm retrieval, in vitro fertilization and embryo culture. The number of attempts of test tube baby is suggested to be 2-3 times, but the situation of each couple is different, and the doctor needs to decide the number of attempts according to the actual situation. The success of IVF is closely related to the age of the woman, the quality of eggs and sperm, and the health of endometrium. Therefore, before IVF, both husband and wife should carefully evaluate their personal conditions, and fully communicate with the doctor to develop their own treatment plan.
