Recently, in the course of answering online inquiries, many of my friends have asked me questions like “What is the difference between IVF and IUI? What is the cost of IUI?”, “How much does it cost?” and “What is the success rate of IVF?” …… From the above questions, we can see that many people don’t know much about IVF, so I will introduce various knowledge about IVF in detail. I. Definition of IVF IVF is the abbreviation for in vitro fertilization embryo transfer, the specific process is to puncture the woman’s eggs through a fine needle, the man will take out the semen to optimize the process, and then put the two together in culture to form an embryo and then put back into the woman’s uterus. Second, the procedure of doing IVF First of all, the first consultation clearly has the indications for doing IVF, and the doctor will recommend doing IVF. After that, the couple will discuss and decide to do IVF and then start to do the comprehensive examination before IVF. In addition, three documents should be prepared, namely the couple’s ID card, marriage certificate, and birth certificate from the family planning department. Finally, the cycle time will be arranged according to the examination results and the ovulation promotion program chosen. Types of IVF 1.First generation IVF: that is, conventional in vitro fertilization-embryo transfer. 2. Second generation IVF: It is intracytoplasmic single sperm microinjection for couples with severe oligozoospermia, obstructive azoospermia, IVM, and previous fertilization disorders in the male partner. 3.

V. IVF cost and success rate The current cost in Yunnan Province is about 20-30,000 per cycle, with a success rate of 40%-50%. Each person’s situation is different, the medication is different, and the cost will be different. The success rate has a great relationship with age. Generally speaking, young patients have a high success rate, and the success rate is very low when the age is older than 40 years old.
