Also known as test tube baby, it consists in joining the oocytes from follicular aspiration and the sperm capacitated previously at the laboratory. Once the oocytes are fertilized and the embryos formed, they are transferred to the woman’s uterus to continue with their natural development.

It is a procedure that consists of the following stages:

Controlled ovarian hyper stimulation:

It is done with a hormonal treatment to assure the multiple follicular developments. This process is initiated between the second and third day of menstruation. It has an approximate duration of 10 days and it is monitored with a transvaginal ultrasound scan (ovulation monitoring scan).

Follicular aspiration:

It is done coordinated by the professional team which principal objective is recovering the ovules in the interior of the follicle. It is performed with epidural anesthesia or intravenous, via intravaginal and guided by ultrasound scan. This procedure lasts 40 minutes approximately; afterwards the patient rests an average of 2 hours and then is released.

Oocytes insemination:

It is performed in the laboratory after evaluating the quality of the oocytes obtained and capacitating the sperm sample, placing a micro drop of semen qualified for each ovule. Then, the fertilization is evaluated and so is the cellular multiplication every 24 hours.

Embryonic transfer (ET):

In this procedure the generated embryos at the In Vitro fertilization laboratory between the third or fifth day of life, are deposited in the woman’s uterus. This practice is done without anesthesia in an ambulatory manner.
