The antagonist protocol does not involve taking fewer eggs, the number of eggs taken is mainly related to the development of the follicles, and if more than one follicle is mature, then of course more than one follicle can be taken.
The antagonist program is an ovulation program for IVF, commonly known as the short program, in which gonadotropin-releasing hormone antagonists are used appropriately after the follicles have reached a certain level of development.
With the antagonist regimen, ovulation is usually promoted from 2 to 3 days after menstruation, and after the follicle grows to about 12 millimeters, gonadotropin-releasing hormone antagonist will be added, followed by HCG injection, and the eggs will be retrieved usually 36 hours after the night injection.
The number of eggs taken on the antagonist regimen is related to the number of follicles that have grown to about 18 mm, usually about 3 mature follicles are taken. However, more than one follicle can be retrieved if there are more than 3 mature follicles.
