1、 Can I make a test tube after ligation?
Yes, it is often said that IVF attempts to have sperm and eggs meet and fertilize in vitro. The specific approach is to use drugs to promote the growth of both ovaries. After maturation, the eggs are taken out, and the culture medium is placed in a culture medium that simulates the human internal environment. The treated semen is added. After a period of training and training, the sperm and eggs can fuse into fertilized eggs and split into 4-8 cells. Then, 2-3 of the best developed embryos are selected and placed back in the uterine cavity to continue growing and developing. In vitro fertilization embryo transfer is a medical term for in vitro fertilization. This is the only choice for couples with tubal obstruction and infertility, and of course, it can also be used to treat infertility that is ineffective for other reasons.
In addition to physical and mental health and the absence of genetic diseases, the conditions for in vitro fertilization should not be too old for couples, especially for women who should not exceed the age of 40. If a woman is too old, the ovarian response to medication will decrease, the number of eggs will be small, and the quality of eggs will also decrease. The fertilization rate and pregnancy rate will also decrease, and the miscarriage rate and fetal malformation rate are higher than those of young women.
2、 The method of in vitro fertilization
1. In vitro fertilization embryo transfer (IVF-ET, commonly known as the first generation in vitro fertilization), mainly targets female infertility.
Suitable for women with various factors causing sperm and egg transport disorders; Ovulation disorders; Endometriosis; Fewer males have weaker sperm.
2. Intracytoplasmic sperm injection (ICSI), commonly known as second-generation IVF, is mainly aimed at severe male infertility.
Suitable for: severe oligozoospermia, asthenozoospermia, and teratospermia; Irreversible obstructive azoospermia; Spermatogenic dysfunction (excluding genetic defects); Immune infertility; In vitro fertilization failure; Abnormal sperm acrosome.
3、 Contraindications for in vitro fertilization
Either party who provides eggs and sperm suffers from acute reproductive, urinary system infections, or sexually transmitted diseases.
2. Any party who provides eggs and sperm has bad habits such as alcohol and drug abuse.
3. Either party provides contact with teratogenic radiation, toxins, and drugs between the egg and sperm and is in the active period.
4. Women suffer from serious genetic diseases, serious physical illnesses, psychological disorders, etc.
4、 The key to the success of in vitro fertilization
1. Age: Age is an important factor for the success of in vitro fertilization technology. Domestic and foreign literature reports that the success rate is highest at 25-34 years old, reaching 45%. After ≥ 35 years old, the success rate is 26% -30%. At 35 years old, the success rate decreases, and at 40 years old, the success rate is around 20%. The live birth rate significantly decreases, and it has a significant impact on eugenics. Generally, those over 45 years old cannot use their own eggs for IVF treatment because the success rate is extremely low and embryonic chromosomes are prone to abnormalities. The abortion rate of middle-aged and elderly people in IVF has increased significantly, and premature birth and stillbirth are also higher than that of young pregnant women.
