Definition and background of IVF
IVF refers to an infant who transfers the fertilized egg into the mother's uterus for development during in vitro controlled fertilization. This technology is a way to help couples who are unable to conceive in a natural way achieve their reproductive aspirations. With the progress of science and technology, IVF technology has been widely used around the world, and provides a choice for young couples and older couples to solve the problem of infertility.

However, with the growth of age, women's ovarian function will gradually decline, and their fertility will also decline. Therefore, for a 42 year old woman, IVF may be an option to realize her fertility desire.
Cost of IVF
The cost of IVF varies by region and hospital. The following is a reference to the cost of IVF in a well-known hospital in London:
1. Cost of preliminary examination: about 1000-1500 pounds, including women's reproductive system examination, male semen analysis, etc.
2. Cost of ovulation promoting drugs: about 500-1000 pounds, used to stimulate ovarian development and produce eggs.
3. Egg retrieval operation cost: about 4000-6000 pounds, including operation cost, anesthesia cost and postoperative care cost.
4. IVF embryo culture cost: about 3000-5000 pounds, including embryo culture and monitoring.
5. The cost of embryo transfer: about 2500-4000 pounds, including the cost of transfer surgery and consultation before and after transfer.
Overall, the cost of IVF in London is between 10000 and 20000 pounds. In addition, other related costs such as drug costs, blood test costs, etc. need to be considered. Therefore, before IVF, both husband and wife should fully understand and make financial preparations.
IVF process
The IVF process usually includes the following key steps:
1. Initial consultation and examination: The couple needs to go to a professional reproductive medical center for preliminary consultation and examination. The doctor will evaluate the couple's physical condition and fertility problems, and formulate a treatment plan according to the actual situation.
2. Ovulation promotion treatment: women receive ovulation promotion drug treatment to stimulate the ovary to produce more eggs. During this process, the doctor will conduct regular ultrasonic examination to monitor the size and number of follicles.
3. Egg retrieval: When the follicle develops to an appropriate stage, the doctor will perform an egg collection operation. This operation is usually performed under local anesthesia, using ultrasound guided fine needles to extract eggs.
4. Fertilization and embryo culture: After taking eggs, the doctor will conduct in vitro fertilization of eggs and sperm in the laboratory. After fertilization, the embryo will continue to be cultured in a petri dish for several days to ensure the development and quality of the embryo.
5. Embryo transfer: After the end of the embryo culture period, the doctor will select the embryo with the most development potential and transfer it to the female uterus.
The whole IVF process usually requires multiple hospital visits, and needs to follow the guidance and monitoring of doctors.
Risk and success rate of IVF
Although IVF technology has achieved great success in helping infertile couples achieve their reproductive aspirations, there are also risks.
Possible risks include multiple pregnancy, pregnancy complications, embryo transfer failure, etc. Multiple pregnancy may lead to premature delivery, bleeding and other serious consequences. Pregnancy complications such as pre eclampsia and gestational diabetes also need attention.
As for the success rate, the success rate of IVF for 42 year old women is relatively low. As the egg quality decreases with age, the possibility of successful pregnancy and embryo implantation also decreases. Therefore, if a 42 year old woman wishes to successfully conceive through IVF technology, the experience of selecting hospitals and experts is very important.
Summary
When a 42 year old woman considers IVF, she needs to know about the cost and process. The cost of IVF includes preliminary examination, ovulation promoting drugs, egg retrieval operation, embryo culture and embryo transfer, which is usually between 10000 and 20000 pounds. The process of IVF involves preliminary consultation and examination, ovulation induction treatment, egg retrieval, fertilization and embryo culture, and embryo transfer. However, the success rate of IVF for 42 year old women is relatively low, and there are certain risks. Therefore, selecting experienced hospitals and experts is the key. For older women, IVF may be an effective choice to realize their reproductive aspirations.
