In these cases the suppression starts from the second day of the cycle and the stimulation one day later. Ultrasound and biochemical testing…
The antagonist protocol begins directly with stimulation on the second day of the cycle, where an ultrasound is performed to check the ovarian state. During the stimulation period the scans and blood tests (measurement of estradiol and LH) and based on the findings, the simultaneous administration of an antagonist (Orgalutran, Cetrotide) to prevent premature ovulation…

It is essentially chorifolitropin α (ELONVA) which is given once on the second day of the cycle and essentially replaces the seven-day injections! From the 6th day it is combined with an antagonist and from the 8th day, if the stimulation is…
