IVF is a procedure performed at the assisted reproduction clinic that is performed at certain stages. The first step is to stimulate the ovaries so that sufficient amounts of eggs are produced through the use of medicines. The eggs produced are then collected by transvaginal suction with ultrasound and sent to the laboratory.
The next step is to evaluate the eggs in terms of their feasibility and probability of fertilization. Thus, after the selection of the best eggs, the sperm is also prepared, selecting the best quality sperm, that is, those with adequate motility, vitality and morphology, because they are the ones who manage to fertilize the egg more easily.
The selected sperm is then inserted into the same vessel in which the eggs are placed, and then the fertilization of the eggs is observed during the embryonic culture so that one or more embryos can then be implanted into the woman’s uterus. , and the implantation attempt should be made by the gynecologist of the assisted reproduction clinic.
To test the success of treatment after 14 days of IVF, a pharmaceutical pregnancy test and pregnancy test should be performed to measure the amount of beta-HCG. About 14 days after these tests, a transvaginal ultrasound may be performed to assess the health of the woman and embryo.

In addition, some babies born using in vitro fertilization techniques have an increased risk of changes such as heart problems, cleft lip, changes in the esophagus, and rectal malformations, for example.
