To increase the chances of success, it is necessary to stimulate the process of woman’s ovulation. This will allow us to obtain more eggs and to detect the exact time of their maturity.
Then, it will be important to follow up the process by regular ultrasound examinations and blood analysis, to determine the required medicine doses and define the treatment days.
When we see that the eggs have reached a necessary condition, we perform their extraction. The procedure is called ovarian puncture, is carried out on an outpatient basis, in an operating room with the use of sedation. The patient can leave the clinic already in 4 hours.
Once the eggs are delivered to laboratory, we start the process of their fertilization. In some cases it will be necessary to perform a sperm micro injection (ICSI), in other words, mechanical sperm introduction into the egg.
The process, although, doesn’t guarantee fertilization, that’s why we continue our observation under the microscope, and after 18-21 hours it becomes possible to say which of the eggs have been successfully fertilized.
Thus, the embryos that come from fertilized eggs, grow under the meticulous control of fertilization specialists, and finally we pick up those with the highest potential for pregnancy.
Three days after the eggs retrieval the embryo transfer is usually carried out. This is a simple painless treatment that doesn’t require anaesthesia.
The number of embryos transferred depends on many factors such as patient’s age, embryo quality etc. It is normally transferred two embryos, the latest tendency although inclines to transfer only one, that allows to eliminate the possibility of conceiving twins.
If more good embryos, than it was necessary to perform successful transfer were obtained, you can use the option of cryo-preserving them for the later use. It can be useful if you didn’t get pregnant from the first try or if you simply want to repeat the experience.
