Artificial insemination is one of the techniques most used in Assisted Reproduction. This technique consists in depositing the treated spermatozoa in the laboratory inside the uterine cavity, after stimulation of the ovaries and subsequent induction of ovulation.
Artificial insemination and its stages



Stages of Artificial Insemination

The stages of the artificial insemination process include ovarian stimulation, semen preparation and introduction of the treated sample into the uterus. These phases are identical in artificial insemination and in artificial insemination with donor semen.
1 . Ovarian stimulation
Physiologically, every month or menstrual cycle, the woman experiences the growth of an egg that is released into the fallopian tubes to be fertilized on the fourteenth day of her menstrual cycle.
In the Artificial Insemination is intended a stimulation of soft and controlled form to the ovaries to increase the possibilities of pregnancy. This ovarian stimulation induces the growth of the follicles (ovarian structures containing the eggs) by administering medication that will make them grow.
It is important to limit the number of mature follicles to 2-3 to reduce the risk of multiple pregnancy while maintaining a reasonable pregnancy rate for this technique.
It is the specialist in Assisted Reproduction who carries out the entire process of ovarian monitoring, which consists of performing ultrasound and hormonal analytical controls to follow up exhaustively, individualized and thus achieve maximum efficiency in each cycle.
2. Preparation of semen
On the same day of the insemination, a sperm sample is obtained and processed in the laboratory of andrology. Subsequently a spermatic training treatment is carried out, with the main purpose of separating and concentrating the spermatozoa of the best quality of the sample in a volume of 0.4 - 0.5 ml and then inserting them into the woman's uterus.
3. Insemination
It is a painless procedure that does not require anesthesia, which is performed in the gynecological consultation itself, lasting the whole process about 30 minutes. It involves inserting a catheter through the cervix into the inside by depositing the sperm sample there.
Insemination is performed just before the ovum is expelled from the ovary and is taken up by the fallopian tubes, a process that occurs 38-40 hours after induction of ovulation.
