Age of IVF
In vitro fertilization (IVF) and embryo transfer (ET) are the methods of implanting the fertilized eggs into the mother's body after a certain stage of development for pregnancy and delivery. So when should IVF babies be conceived? The following is a detailed description from four aspects: embryonic development, maternal age, physiological conditions and medical factors.
embryonic development
The embryonic development stage of IVF has an important impact on the timing of pregnancy. Generally, the best time for IVF is when the fertilized egg enters the most receptive endometrium, that is, the embryo is in the early embryonic stage from the 3rd to the 5th day. At this time, the embryo presents the morphology and physiological activity suitable for successful implantation into the uterus, facilitating the occurrence of pregnancy. Therefore, the key to IVF is to select embryos at appropriate developmental stages for implantation.
However, not all embryos can reach the ideal development state. Sometimes, doctors will choose an earlier or later implantation time according to individual conditions. For example, for older women or women with certain diseases, doctors may choose to catalyze ovulation and take out early formed eggs, conduct in vitro fertilization and culture in the laboratory, and then implant embryos into the uterus. Therefore, the selection of embryonic development stage can vary from person to person, and needs to be determined according to the doctor's suggestions and individual conditions.
Maternal age
Maternal age is another important factor in IVF pregnancy. Women's fertility will gradually decline with age. Generally speaking, the quality and quantity of eggs for women between puberty and 35 years old are suitable for fertilization and embryo transfer. However, with the growth of women's age, the quality and quantity of eggs will gradually decrease, leading to lower pregnancy and pregnancy success rate.
For women over 35 years of age, especially those over 40 years of age, due to the decline in egg quality, it is necessary to be more cautious in choosing the timing of implantation. Usually, these women need to carry out IVF pregnancy at the early stage of the menstrual cycle to improve the possibility of successful pregnancy.
Physiological conditions
In addition to embryonic development and maternal age, the maternal physiological conditions should also be considered when IVF is pregnant. The mother needs normal endometrial thickness and blood supply so that the embryo can be implanted and developed well in the endometrium. In addition, the mother also needs to have a good level of reproductive hormones and ovarian function to ensure the quality and quantity of eggs. If the mother has physiological problems, such as endometriosis, polycystic ovary syndrome, etc., it needs to be treated and adjusted under the guidance of doctors to improve the probability of successful pregnancy.
Medical factors
Finally, medical factors should be taken into consideration when IVF is pregnant. It is very important to choose a formal and professional IVF hospital for treatment. Different hospitals may have different technical levels and equipment conditions. Choosing a hospital with high success rate and rich experience can improve the success probability of IVF. In addition, doctors' experience and professional knowledge are also important factors that affect the age of IVF pregnancy.
To sum up, the age of IVF pregnancy needs to consider embryonic development, maternal age, physiological conditions and medical factors. The success rate of IVF can be improved by selecting the appropriate embryonic development stage and pregnancy time, as well as the appropriate hospital and doctor according to individual conditions.
