What is the reason why many couples have not been able to give birth to their own beloved offspring after getting married? It can only be said to be a symptom of infertility. In this case, it is difficult to relieve the relationship between husband and wife. The editor suggests that there are exquisite IVF techniques in China now, and you can try them out. Let's take a look together!
Will it hurt to do IVF egg retrieval
IVF can be said to be painless throughout the entire surgical process, but there may be some pain or discomfort during egg retrieval, but this still depends on the specific situation of the patient. However, for patients with more severe symptoms, moderate use of sedatives is recommended, so it is completely tolerable and patients do not need to feel afraid.
The process of doing IVF
1. Stimulating ovulation: Generally, normal women only release one egg per month, but sometimes one egg is not enough for "in vitro fertilization". Therefore, different drugs can be used, such as recombinant human follicle stimulating hormone (gonadotropin) for injection, human menopausal gonadotropin (hMG) for injection, and human chorionic gonadotropin (hCG) for injection, to enable patients to release multiple eggs in one cycle.
2. Predicting ovulation: To do "test tube baby", mature eggs need to be taken before ovulation, so the first step is to determine the ovulation period. In clinical practice, basal body temperature measurement, cervical mucus examination, vaginal smear, and mainly B-ultrasound monitoring of follicle development can be used to determine the optimal time for hormone induced ovulation.
3. Egg collection: There are generally three methods, each with its own advantages and disadvantages, which can be selected based on the patient's indications and objective medical conditions.
① Cesarean exploration and egg retrieval: This is an early method used. Its advantages are that during laparotomy, certain diseases can be corrected simultaneously, such as tubal adhesion separation surgery, recanalization surgery, etc. It can also select appropriate eggs under direct vision and directly extract follicular fluid, which is easy to operate and has a high egg retrieval rate. But the surgical trauma is significant and the cost is also high.
② Laparoscopic egg retrieval: This method is the most widely used. Under laparoscopy, follicular egg retrieval can be performed through trocar puncture, while other pelvic lesions can be observed and some feasible surgeries can be performed with minimal surgical damage. But laparoscopic equipment and techniques are required, and the injection of CO2 (carbon dioxide) into the abdomen during laparoscopy can lead to a decrease in the fertilization ability of the egg.
③ Transvaginal egg retrieval under B-ultrasound guidance: It is performed by puncturing the posterior fornix of the vagina to retrieve eggs. This method of egg retrieval is particularly simple, safe to operate on, does not require hospitalization, and saves costs. But the instruments are more expensive, the operating techniques are slightly more complex, and the number of follicles is not as large as that of direct visualization puncture.
4. Egg culture: The pre ovulatory mature eggs obtained are processed by special techniques and wait for fertilization.
5. In vitro fertilization: The semen obtained by the husband under sterile conditions is processed to give the sperm the ability to penetrate the egg and become fertilization droplets. It is then added to a culture medium containing the egg and fused into a new cell, the fertilized egg, through binary prokaryotic fusion. After further cultivation until it divides into 4-8 cells, intrauterine transplantation can be performed.
6. Embryo transfer: The early embryos mentioned above are taken out of the culture medium and injected into the uterine cavity. It is best to transfer 3-4 fertilized eggs at once, which can improve the success rate of pregnancy after transfer. The conditions for successful embryo transfer are: the vitality of the fertilized egg itself, whether the endometrium is healthy, and whether there is any damage during the transfer process.
7. Post pregnancy measures: When the embryo is successfully transferred to the uterine cavity, high-risk pregnancy management should be carried out, closely followed up, various necessary hormone tests and routine examinations should be performed, and measures to protect the fetus should be taken.
Perhaps you may be worried about the pain of undergoing in vitro fertilization (IVF). The previous article has summarized the relevant content for everyone. IVF is also a last resort, and normal couples can have their own children through sexual activity. If you need to undergo IVF, you must first take care of your own body! This way, we won't do such unnecessary work!
