IVF egg retrieval process
Test tube baby is an assisted reproductive technology, which is suitable for couples who cannot conceive naturally. Fetching eggs is one of the key steps in IVF. Next, we will introduce the process of IVF egg retrieval in detail from four aspects: preparation before egg retrieval, egg retrieval operation, egg quality assessment and subsequent embryo transfer.
1. Preparation before egg retrieval
Before IVF egg retrieval, the doctor will conduct a detailed physical examination and assessment of the patient, including checking the ovarian function, uterine condition and excluding other infertility factors. Doctors will also develop personalized treatment plans according to the specific conditions of patients. About one month before egg retrieval, patients need ovulation induction treatment to increase the number and quality of eggs.
In addition, relevant examinations such as endocrine examination, blood routine examination, hepatitis B, AIDS and other infectious diseases should be carried out before egg retrieval to ensure the safe and smooth operation of egg retrieval.
Within a few hours before egg retrieval, the patient needs to fast to ensure an empty stomach during the operation.
2. Egg retrieval
Egg retrieval is the most critical step in IVF. Before egg retrieval, the patient will receive general anesthesia or local anesthesia to ensure the comfort and painless feeling of the operation process.
Doctors will insert a slender catheter through the vagina, guide it to the vicinity of the ovary, and use ultrasound technology to locate the follicles in the ovary. Then, puncture the follicle through a catheter and suck out the egg. This process is usually completed in 10-20 minutes.
After the egg retrieval operation, the patient needs to rest for a while, waiting for the effect of anesthesia to subside. Usually, patients can leave the hospital on the same day, and recover and rest according to the doctor's advice.
3. Egg quality assessment
After taking the eggs, the doctor will evaluate the quality of the eggs. The quantity and quality of eggs are crucial to the successful IVF process.
The egg quality can be evaluated by observing the shape, size and cytoplasm color of the egg. Generally, the rounder the egg, the higher the transparency, and the uniform color of the cytoplasm represent the better egg quality.
At the same time, doctors will also evaluate the fertilization ability of eggs to determine which eggs can combine with sperm to form an embryo.
4. Subsequent embryo transfer
After taking eggs, eggs will combine with sperm to form embryos. Doctors will select the best embryo for transplantation according to the quality and quantity of eggs.
Embryo transfer is usually carried out three to five days after egg retrieval. The doctor guides the embryo into the uterus through the vagina and places it in an appropriate position. After transplantation, patients need to continue to take hormone drugs to help embryo implantation and pregnancy.
After embryo transfer, the patient needs to wait several weeks for pregnancy test to confirm whether the pregnancy is successful.
summary
IVF egg retrieval is a key and complicated surgical procedure. Under the guidance of professional doctors, patients need to carry out preparations, egg retrieval operations, egg quality assessment, embryo transfer and other steps. Through reasonable treatment plan and doctor's guidance, IVF egg retrieval process can help many couples who cannot conceive naturally realize their reproductive dreams.
