Will the follicles grow after taking the night injection?

For women who have difficulty getting pregnant, doctors will use medical methods to promote the formation of follicles, and night injections are a common method. Before taking the night injection, women may wonder if the follicles will still grow after the night injection? First of all, it is necessary to be sure that the follicles will continue to grow after the night injection. The night injection is mainly for the follicles to form more mature, so as to arrange the time for egg retrieval and then perform in vitro fertilization.

After the night injection, the follicles will still grow under the action of follicle-stimulating hormone, or FSH, but they usually will not grow too much because the current follicles are basically mature. Egg retrieval is usually arranged 36 hours after the night injection. Egg retrieval is usually performed under painless general anesthesia. After egg retrieval, you should pay attention to rest, reduce activity, eat a light diet, drink more water, and urinate more.

When using IVF technology to assist pregnancy, you will often hear a word - "night injection". During the ovulation process, when the follicles grow to a certain stage, doctors usually use a special drug to induce the oocyte to reach final maturity. Since the drug injection time is generally scheduled at night, it is called the "night injection", also known as the HCG injection.

Why do we need night injections?

Because the egg is wrapped by cumulus cells and adhered to the wall of the follicle, the role of the "night needle" is to promote the maturation of the egg, loosen the cumulus cells, make the egg easier to fall off the follicle wall and be discharged, and the doctor can retrieve the egg more easily.

The timing and dosage of night injections are very important

The timing of the night injection is very important. If HCG injection is too early, the proportion of immature nucleus and cytoplasm of the oocyte will be high, and its developmental potential will be affected. If HCG injection is too late, the oocytes may be over-mature, which also increases the risk of elevated progesterone and ovarian hyperstimulation syndrome, so the appropriate HCG timing is important. The doctor will determine the dosage of the drug and the time of injection based on the patient's condition, such as the number of follicles, follicle development, endocrine levels and other factors.

What should you pay attention to when taking a night shot?

1. Timing: Patients must strictly follow the doctor's instructions to inject the night injection. Those who fail to inject on time or fail to inject should contact their attending physician in time and follow the doctor's instructions for remedial treatment. If necessary, they can call the hospital's emergency number.

2. Rest: After taking the night injection, you should pay attention to rest, eat a proper diet, and do light activities to avoid ovarian torsion or premature ovulation due to strenuous exercise.

3. Medication: Do not take medication at will or stop taking medication at will after the night injection. If you have other physical illnesses that require medication, you must inform your attending physician in time.

4. Storage: If you are taking the medicine home for injection, store it according to the nurse's instructions or the requirements of the medicine instructions after receiving it (pay special attention to the temperature).

5. Egg retrieval: Egg retrieval is usually done 34-38 hours after the night injection. You must arrive at the hospital on time on the day of egg retrieval, make preoperative preparations as required, and prepare all the necessary documents.

Generally, night injections are scheduled at night. If you are getting a night injection in the hospital, arrive at the hospital on time as ordered by the doctor, and there will be a nurse on duty that night to give you the injection. In addition, for some patients, night injections may be scheduled at other times, such as in the afternoon. But no matter when the injection is given, you must follow the doctor's instructions and take the medicine on time strictly, otherwise it may lead to adverse consequences such as premature ovulation and immature eggs.
