The length of the OPU (ovum pick up) depends on the number of follicles in the ovaries. Yet, on average, it takes about 15-30 minutes. Considering pre-procedure preparations, the procedure itself and post procedure and rest, you should at least allocate 3 hours for the procedure.
Is OPU (Ovum Pick Up) a painful process?
OPU (ovum pick up) is not a very painful procedure which can be done even without any medication. Nevertheless, intravenous sedatives and painkillers help to go through the procedure in the least discomfortable way. Besides, if a patient chooses to be fully sedated during the procedure, the doctor can make arrangements accordingly.
How do you feel after ovum pick up?
You might feel sleepy due to the anaesthetic effects of medication. There might some abdominal discomfort. If you feel well enough, you can go back to work the next day.
Does every follicle (during ovum pick up) contain an egg?
No. However, if there are plenty of follicles, it might not be possible to count all properly. In that case, there might be more eggs than monitored via ultrasound scan. However, if ultrasound scan shows few follicles, there is a chance of not having any eggs.
Rarely, in some cases, although there are lots of follicles in the ovaries, there might be no eggs within the follicles (empty follicle syndrome). Although this situation is known as to be a result of "apoptosis" which leads to the early decline of the ovaries/eggs, the mechanisms behind it cannot be explained fully.
Does every egg collected for IVF provide fertilization?
The average fertilization rate is 65%. Some couples may experience a higher rate, whereas, although rarely, some couples may, unfortunately, see no fertilization.
How can sperm be obtained after OPU?
In OPU, eggs are collected by entering the ovaries via transvaginal ultrasound with a thin needle. After they are collected, mature ones are determined and then, they are prepared for fertilization. Sperm is collected by masturbation from men, whose semen contains sperm. For those whose semen does not contain any sperm, there is the option of searching for sperm via a surgical operation to the testes and if found, they are collected. These types of patients are known as azoospermic males, and the chances of finding sperm in that way is about 50%. If azoospermia is a result of obstruction, then sperm can definitely be found.
When can embryos be frozen?
They can be frozen anytime up to six days after fertilization decided by the IVF team.
How long can frozen embryos be stored?
No one knows for certain. However, laws limit this duration to three years. It is known that storing for this and even longer periods of time proved successful
Will all excess embryos (not needed and used for transfer) be frozen?
Not all embryos show the desired development. In order to freeze them, they should be at a desired development and shape. If you have frozen embryos before the day of embryo transfer, you should be made aware of that.
When can I start doing daily activities such as walking, driving or working?
You can go back to your daily life in two days after the transfer. If your job is stressful and tiring, you may want to talk to your doctor about it.
When can we have sexual intercourse after embryo transfer (ET)?
You shouldn't have sexual intercourse until we get the results for pregnancy tests.
How long should rest after the transfer?
You can lie down on a bed in a position you are comfortable with or you may sit on a chair. Except for WC and such essential needs it will be enough to rest for a few days. If you live out of town (in another country), we suggest you rest for one day before the travel.
