What is the difference between in vitro fertilization and artificial insemination?

Artificial insemination VS in vitro fertilization

In terms of fertility, we find different types of treatments and assisted reproduction techniques, which can allow men and women with infertility to achieve a pregnancy, thus fulfilling the illusion of having children.

At Celagem all our patients are important and we understand that each case brings with it different fertility problems, so each of the techniques is indicated for different patients. That is why it is necessary to make it clear which treatment is the most appropriate to guarantee success.

Artificial insemination and in vitro fertilization are two of the most widely used treatments in the world, which makes them well known today, but at the same time these two terms tend to be confusing or in other cases they think they can be the same . We will explain each of them below. 

Artificial insemination

It is one of the simplest assisted reproduction techniques, which is why it tends to be, in most cases, a treatment indicated as the first option. This consists of taking the couple's semen sample to the laboratory where the sperm with the highest fertilization potential will be selected and then implanted in the woman's uterine cavity, where fertilization occurs naturally at the time of ovulation. 


Artificial insemination is indicated for couples whose sperm count or mobility decreases, as well as due to difficulty in penetrating sperm into the uterine cavity due to cervical problems or the presence of antibodies against semen, among other factors. 

In vitro fertilization

It consists of ovarian stimulation, which seeks to obtain a greater number of eggs, which will be extracted by puncture of oocytes, to be fertilized with sperm, either from the couple or from a donor through fertilization and embryo culture, finally the The patient's uterus will be deposited in the patient's uterus according to its evolution, to give them the best chance of achieving pregnancy and to be able to perform a positive test on the stipulated date after the end of the treatment.

In vitro fertilization is indicated for patients with more serious infertility problems, such as women with low ovarian reserve, blocked fallopian tubes or tubal ligation (pomeroy), moderate or severe male factor, and in failed cases of Artificial insemination.

The in vitro fertilization , in turn, is a more complex assisted reproduction technique, which aims to obtain one or more embryos of optimal quality that can be transferred to the patient's uterus to allow the occurrence of pregnancy.
