The next step is ovarian stimulation, also known as controlled ovarian stimulation (COS). You will be prescribed fertility medications, typically in the form of injectables, to stimulate the ovaries and promote the development of multiple mature eggs. The medication protocol will be tailored to your specific needs and closely monitored through regular ultrasound scans and hormone level assessments.

Once the eggs have reached the desired level of maturity, an egg retrieval procedure is scheduled. This is typically performed under ultrasound guidance and light anesthesia. A thin needle is inserted into the ovaries via the vaginal wall, and the follicular fluid containing the eggs is aspirated. The procedure usually takes about 15-20 minutes, and the eggs are then handed over to the embryology laboratory.

On the same day as the egg retrieval, the male partner or sperm donor provides a fresh semen sample. Alternatively, previously frozen sperm can be thawed. The sperm sample undergoes processing in the laboratory, which involves washing and separating the sperm from the seminal fluid.

Following fertilization, the embryos are cultured in a controlled laboratory environment. The embryologists monitor their development over several days, assessing their quality and progression. The goal is to allow the embryos to reach an optimal stage of development before transferring them to the uterus.

In certain cases, preimplantation genetic testing (PGT) may be recommended. PGT involves the biopsy of one or a few cells from each embryo for genetic testing. This can screen for chromosomal abnormalities or specific genetic conditions, helping select the healthiest embryos for transfer.

Based on factors such as embryo quality, the number of embryos available, and individual circumstances, the most suitable embryos are selected for transfer. The embryo transfer procedure is typically performed without anesthesia. A thin catheter containing the embryos is carefully inserted into the uterus through the cervix. The embryos are then released into the uterine cavity.

After the embryo transfer, you will be advised to rest for a short period before resuming normal activities. A pregnancy test is usually scheduled around 10-14 days after the embryo transfer to determine if the treatment has been successful. If the test indicates a positive pregnancy, additional monitoring and support will be provided to ensure the well-being of the pregnancy
