Ivf Science of Oocyte Harvester and Oocyte Harvesting Surgery

Egg retrieval is a very minor procedure that can be performed under general or local anesthesia. Ultrasound examination in the vagina revealed that after the needle of the egg retrieval needle passed through the vagina to the ovary, the egg retrieval personnel immediately transferred the retrieved eggs to a petri dish containing embryo culture medium and cultivated in a 37°C incubator. Because vaginal ultrasound aspiration is a minor surgery, some egg workers will use some pain relievers instead of general anesthesia to save time.

The Minvitro oocyte harvester offers the following advantages:

1. The puncture needle is made of imported medical steel, which has both toughness and rigidity, and is easy to puncture.

2. The needle tip adopts the back edge design, the needle tip is sharp, the puncture is smooth, and the pain and discomfort of the patient are reduced.

3. The mirror polishing process of the inner wall can effectively prevent the phenomenon of hanging eggs and improve the egg retrieval rate.

4. Single-chamber and double-chamber specifications and models are complete, which can be selected according to clinical needs.

Under normal circumstances, the egg retrieval time is less than 30 minutes. Women experience mild pain and a small amount of bleeding after egg retrieval. You can go home after lying in the hospital for an hour or two. Such minor operations will not interfere with normal life. Because the follicles are different in size, the mature stage of the retrieved eggs is also different. Some eggs may be immature, but some may be overripe.

1. Things to pay attention to the day before egg retrieval:

1. Pay attention to rest and avoid strenuous exercise.

2. Fasting after 12 o'clock in the evening, no water, until after the egg retrieval surgery.

3. Please do not use cosmetics, perfume, nail polish.

4. Please try to remove jewelry (necklaces, rings, earrings, bracelets, watches, etc.), dentures, hairpins, contact lenses and other items and accessories as much as possible.

5. Please take a bath with clean water and change your underwear.

2. Matters needing attention after egg retrieval surgery:

1. Lie on your back after returning to the rest room, and eat after being evaluated by the nurse.

2. Eat light and easily digestible food after waking up from anesthesia (avoid gas-producing food such as milk and carbonated drinks).

3. Driving and mechanical operations are prohibited within 24 hours after anesthesia.

4. After the egg retrieval operation, try to turn over gently and reduce activities, especially avoid strenuous exercise (to prevent ovarian torsion and intra-abdominal bleeding).

5. Do not leave by yourself after the egg retrieval operation.

6. If you have symptoms such as abdominal pain, stomach pain, vaginal bleeding (here, the blood volume is greater than the usual menstrual volume), oliguria (24-hour urine volume is less than 1000ml) and other symptoms, you must come back to the doctor in time.

3. Matters needing attention in embryo transfer:

1. It will usually be arranged on the third day after egg retrieval.

2. Before embryo transfer, be sure to urinate in advance.

3. After embryo transfer, stay in bed for at least 2 hours. Generally, you can eat, drink, turn over and get out of bed to urinate, but be careful not to hold back your urine to avoid urinary retention and urinary tract infection.

4. Do not have sex after embryo transfer, and do not use tub baths.

5. After the embryo transfer, try to keep your mood as comfortable as possible. A good mood is conducive to a successful pregnancy.

6. No need to stay in bed for a long time, normal non-exhaustive work or life is acceptable.

7. If you have symptoms such as abdominal distension and oliguria, you must come back to your attending doctor in time.

8. Generally, on the 14th day after embryo transfer, you can go to the hospital to check whether the pregnancy is successful.
