In the last issue, we talked about how to eat during IVF to grow large, round follicles. So if the follicle matures, is it possible to perform egg retrieval immediately? No, there is one more procedure that needs to be done before the egg retrieval is done, that is, night injections. I believe that there are many sisters who have certain doubts about "night injection", what is night injection? Why do I need a night injection? What are the benefits for follicles?
Why do IVF need night injections? What is Night Needle? Why did it play at night?
When we perform IVF, we need to perform a hypnotic injection for several consecutive days. Why do test tubes need to be drained?
You know, we women only have 1 ovulation a month. In the same batch of follicles, only one dominant follicle releases the egg. That if you do test tubes, the number of eggs is not enough, in order to improve the success rate of test tubes, you must have more eggs and sperm fertilization, and cultivate a certain number of embryos.
What is a night needle?
When doing the IVF, you will find that the last needle was given at night, what is this night injection?
When the follicle grows to a certain stage, it is necessary to use drugs to promote oocyte maturation, the drug is generally human chorionic gonadotropin (HCG) or short-acting gonadotropin-releasing hormone agonist (GnRH-a), the injection time is generally in the evening, so it is called "night needle".
So why do we need night injections?
Because the egg is wrapped in mound cells and adheres to the follicle wall, the role of the "night needle" is to promote the egg to mature, and then let the egg mound cells loose, so that the egg is easy to fall off the follicle wall, so that we can just easily get the egg. To put it simply, night injections are given to promote egg maturation and shedding.
When are night injections?
They all said it was a night needle, and it must have been shot at night. However, it is generally necessary for the doctor to determine the patient's follicle size, hormone size, and other factors.
Doctors determine this based on the patient's follicle size, hormone levels, and other factors. The timing of the injection is important, the injection time is too early, the morphology and function of the follicle are not yet mature, and the egg acquisition fails.
If the injection time is too late, the oocytes may be overripe, the quality may be degraded, or even discharged early, missing the more appropriate timing of fertilization. Therefore, it is important to grasp the best time.
Why is it usually night injections at night?
Eggs generally mature about 35-36 hours from the night injection, so in order to be able to retrieve the eggs in the morning, they should be injected in the evening. However, in individual patients (e.g., natural cycles or microstimulation cycles), night injections may be advanced and may be injected at noon or in the afternoon on the day of the night injections.
Regardless of the time, the medication must be taken according to the doctor's order, otherwise it will affect the outcome of egg retrieval, such as premature ovulation, egg immaturity, etc.
Now you know why IVF requires night injections, which are given to allow the eggs to rupture better. I also hope that the Jimei can test a successful tube, what do you want to know about the test tube knowledge, you can leave a message to me at the bottom!
