“The success rate of IVF is affected by a number of factors, and in addition to technology, medication and other factors, age is one of the most important factors. The success rate of young patients is significantly higher than that of older ones. Infertile couples are advised to go to the hospital as soon as they decide to undergo IVF for relevant examinations and to determine the treatment time and plan. Due to the interaction of disease, psychological, environmental and social factors, the number of infertile people in China has increased significantly in recent years. China’s IVF technology has developed more rapidly, and the incidence of infertility in China is around 10%, which is close to the level of developed countries. With the Ministry of Health not re-emphasizing the limitation of the number of cycles (a couple needs to undergo one or more cycles of treatment), the number of cycles has increased in most of the centers. Age is the most important factor affecting: the success rate In the case of the Reproductive Center of Guangdong Maternal and Child Health Hospital, the number of cycles per month at the center has increased from about 100 in the past to more than 200 at present, and the trend continues to grow. With the improvement of technology, reagents, instruments and other conditions, the success rate of IVF has also gradually increased, from about 20% in the past to 40%-50% at present. “The success rate of IVF is affected by many factors, except for technology and drugs, age is one of the most important factors. The success rate of young patients is significantly higher than that of older patients. For patients younger than 35 years old, the success rate of each cycle can be more than 50%. What age is suitable for IVF 1, the woman’s age is very critical 35 years old is a “hurdle” IVF is the treatment of infertility a method of pregnancy, but infertile couples have to meet certain conditions in order to do IVF, the age of the problem is also an important factor to consider. Like normal female pregnancy, miscarriage can occur with this method, and depending on the patient’s own physical condition and other factors, older women are at a higher risk of miscarriage. 2, not contraceptive one year not pregnant should be timely to do the examination To do IVF should meet certain conditions, want to do IVF surgery couples have a variety of indications for the limitations, however, they must first of all check out infertility symptoms. In addition to IVF techniques that can treat infertility, there are other methods that can be used and there are some couples who can get pregnant with methods that promote ovulation in the female partner or with tubal treatments. Therefore, IVF with in vitro fertilization is just one of the treatments, and the doctor will come up with an optimal treatment plan for each patient, depending on the patient’s situation. Conditions: Couples need to undergo rigorous screening Although IVF technology is a proven solution to infertility, it must not be abused. The technical specifications for IVF are demanding, and it is important to go to a qualified hospital for this technique. In addition, IVF is not something that can be done just because a patient wants it. It must be performed only by infertile couples with indications that have been rigorously screened by a doctor. Indications for IVF include blocked fallopian tubes, endometriosis, and ovulation disorders in the female partner, and severe oligozoospermia and obstructive azoospermia in the male partner. A cycle takes 2 to 3 months Due to the lack of relevant professional knowledge, many couples do not have a good understanding of the process of IVF. It takes about 2 to 3 months to complete a cycle of IVF, including routine pre-operative checkups, medical records, signing of informed consent, ovulation induction, egg retrieval, embryo transfer, etc. The entire treatment process does not require hospitalization, and egg retrieval and embryo transfer are not required. There is no need to be hospitalized for the entire treatment, and you can leave after the egg retrieval and transfer with only a short rest. Common complications of IVF include ovarian hyperstimulation syndrome, multiple pregnancies, miscarriages and ectopic pregnancies. In case of complications, the doctor will do appropriate treatment according to the specific situation, so there is no need to be nervous. Eugenics: Advocating single embryo transfer Is a child born through IVF as healthy as a child born through natural conception? This is a common concern. Generally speaking, IVF is safe and has been developed worldwide for more than 30 years. In 2007, the first IVF baby, Louise Brown, had a natural pregnancy and gave birth to a healthy second generation. Numerous studies at home and abroad have shown that there is not much difference in intelligence and physical fitness between children born from IVF and those born from natural pregnancies. Indeed, some experimental studies have shown that there is not much difference between the two, except that the former’s social behavioral ability is lower, which may be related to the fact that these children are highly pampered, and has nothing to do with the “test tube baby” technology itself. However, because of the high number of twin pregnancies in IVF, which can lead to an increase in low birth weight babies, single embryo transfer is worth advocating from the point of view of eugenics. What preparations should I make before undergoing IVF? Couples should make the necessary preparations before undergoing IVF. Couples who are eligible to undergo IVF should first provide ‘three certificates’, i.e. Family Planning Service Certificate, Marriage Certificate and Identity Card. Then they have to undergo some routine examinations. If they are found to be suffering from infectious diseases, sexually transmitted diseases or major illnesses that cannot tolerate pregnancy, etc., the technique cannot be performed.
