In case of a bilateral salpingectomy, that is, in the absence of both Fallopian tubes, pregnancy cannot occur naturally. In these cases we must resort to In Vitro Fertilization (IVF) to achieve pregnancy.
In IVF, as its name indicates, the fertilization of the egg is performed in the laboratory (in vitro), so that we do not need the fallopian tube to perform its function.
We extract the eggs directly from the woman's ovaries through a procedure called follicular puncture. We take these eggs to the laboratory, where we perform the fertilization of the egg with the sperm of the couple or a donor. In this way we obtain embryos. The embryos are then transferred into the woman's uterus to achieve pregnancy.
In fact, the pathology of the fallopian tubes (tubal pathology), either by absence (post-salpingectomy) or by alteration of its function (obstruction, dilatation, etc.), was what led to the research and development of the first IVFs in history.
