The term in vitro fertilization refers to where fertilization takes place. With IVF, fertilization occurs in the laboratory (in vitro).
The woman undergos hormone treatment to encourage her ovaries to develop multiple mature eggs.
Around the middle of the menstrual cycle, usually around the 12th-16th day, the oocytes are retrieved in a follicle harvesting. The retrieval is performed under a short, non-invasive procedure using general anesthetic under ultrasound guidance.
The procedure takes about 15 minutes and is performed on an outpatient basis.
The retrieved eggs are brought together with the processed sperm in the laboratory. After about 2 to 5 days, the embryos are inserted through the vagina into the uterine cavity by means of a thin plastic catheter. The embryo transfer takes only a few minutes, is usually painless, and is also performed on an outpatient basis and without anesthesia.
Intracytoplasmic sperm injection, or ICSI for short, is performed when the sperm needs help fertilizing the egg.
At the beginning of the menstrual cycle, a hormonal stimulation of the ovaries is performed in order to allow several eggs to mature.
In the middle of the cycle, the oocytes are retrieved during follicle harvesting.
The harvesting is performed under ultrasound control in a short and non-invasive general anesthetic.
The best sperm are then selected in the laboratory and inserted directly into the egg cell under a special microscope.
After 2 to 5 days, the embryos can be transferred to the uterus. They are inserted through the vagina into the uterine cavity by means of a thin plastic catheter. The embryo transfer only takes a few minutes and is also performed on an outpatient basis. The procedure is usually painless and can be performed without anesthesia. werden.
