Egg Retrieval Cycle:

To start the egg retrieval cycle, you will begin on day 2 or 3 of your menstrual period. The clinic will use Individualized Controlled Ovarian Stimulation (iCOS) to help the follicles in your ovaries grow. These follicles are small sacs filled with fluid that contain immature eggs. Once the follicles reach the optimal level of maturity, they will give you a trigger shot to stimulate ovulation. After that, they will proceed with the egg retrieval procedure, which usually takes place around day 14. The retrieved eggs will then be fertilized with sperm to form embryos.

Embryo Cultivation and PGS (Preimplantation Genetic Screening):

After 5-6 days of development in the laboratory, the embryos will be biopsied when they reach the blastocyst stage. The cells will be sent for PGS while the embryos are frozen.

ERA (Endometrial Receptivity Analysis):

By the third day of your menstrual period, a mock embryo transfer cycle can be performed to determine the window of implantation (WOI). This will help the clinic identify the specific timeframe when your endometrium is receptive to the embryo.

Embryo Transfer Cycle:

The embryo transfer cycle begins by the third day of your menstrual period. You will start taking medication to prepare your uterus for implantation. Once the uterine lining reaches a satisfactory thickness, the clinic will proceed with the embryo transfer during the implantation window, which typically occurs around day 18-20. After that, pregnancy can be detected 7-14 days after the embryo transfer.
