What is ovum pickup procedure?
The Ovum Pick Up technique consists in the transvaginal removal of the oocytes by aspiration of the ovarian follicles with the aid of an ultrasound probe. This procedure is absolutely harmless to the donor, the time taken for the collection is 15-20 minutes during which the donor is contained in a cattle crush.
When oocyte is retrieval done?
Oocyte retrieval is typically performed 35 to 36 hours after hCG administration by a transvaginal sonography-guided technique.
How oocytes are collected during IVF?
The follicular fluid (which contains the eggs) from the follicles in your ovaries is collected in test tubes and passed to the embryologists in the In Vitro Fertilization (IVF) Lab. The egg retrieval takes approximately 20-30 minutes.
What is the purpose of oocyte retrieval?
Oocyte retrieval is done to remove eggs from a woman’s ovaries.
What do I do after oocyte retrieval?
Recovery after egg retrieval
- Treat discomfort with a heating pad and rest.
- Ask the physician to recommend pain medication if discomfort continues.
- Avoid heavy lifting and vigorous exercise, as ovaries are still enlarged during this time and may be tender.
- Avoid alcohol or caffeine.
How is IVF done step by step?

What releases the oocyte?
The ovaries
The ovaries release an egg (oocyte) at the midway point of each menstrual cycle. Usually, only a single oocyte from one ovary is released during each menstrual cycle, with each ovary taking an alternate turn in releasing an egg. A female baby is born with all the eggs that she will ever have.
What is an oocyte composed of?
Note that the oocyte is a large cell with a large nucleus containing a prominent nucleolus. Primary unilaminar follicles consist of an oocyte surrounded by a single layer of cuboidal follicular epithelial cells.
How long does the oocyte pick up take?
OOCYTE PICK-UP (OPU) OPU procedure is performed under light general anesthesia and it lasts 10 to 15 minutes. Follicles growing in both ovaries are aspirated by a needle with trans-vaginal ultrasonographic guidance. Following OPU, our patients rest at our center for 30-45 minutes, thereafter they go home.
How is oocyte extraction and decumulation performed?
Once the extraction is done, the sample is analyzed in the microscope to select and carry out the oocyte decumulation, a process where the granulosa cells surrounding the oocyte are removed. Initially performed using transabdominal ultrasonography, TVOR is currently performed with a transvaginal ultrasound transducer with an attached needle.
How many oocytes are removed from the ovaries during a hysteroscopy?
Once the ovarian follicles have been aspirated on one ovary, the needle is withdrawn, and the procedure repeated on the other ovary. It is not unusual to remove 20 oocytes as women are generally hyperstimulated in advance of this procedure.
What is the Opu procedure like?
OPU procedure is performed under light general anesthesia and it lasts 10 to 15 minutes. Follicles growing in both ovaries are aspirated by a needle with trans-vaginal ultrasonographic guidance. Following OPU, our patients rest at our center for 30-45 minutes, thereafter they go home.
