In artificial insemination (AI) it is important to know the ideal moment to perform the insemination, that is, to place the semen in the uterus.
For this it is essential to do ultrasound controls to control the size of the follicle. In the case of elongated follicles, two diameter measurements are always taken to see the real size of the follicle in order to know at what moment to induce the ovulation externally, with the administration of ovitrelle.
The moment when the dominant follicle reaches about 17 mm is usually on day 9 of the stimulation cycle, but there are women who reach the size of 17 before or after. That is why it is so important to do ultrasound controls every 48 hours.
