1) Increased egg production
After your normal cycle begins, you will be given a known fertility hormone called gonadotropin. You usually inject it daily for 12 days. This hormone increases the number of eggs you produce.
2) Monitor progress
The clinic will monitor your progress during drug treatment by scanning your vaginal ultrasound. The first scan is usually 7 days after the first injection. Between 34 and 38 hours before the eggs are collected, a hormone is injected to help your eggs mature. The timing of the injection, which is usually done at 10 pm, is very important at this stage.
3) Collection of eggs
Your eggs are usually collected through ultrasound guidance when you are unconscious. An empty needle is attached to the ultrasound probe and collected from the follicle in each ovary. You may experience some pain and bruising, cramping, or, to a lesser extent, bleeding from your vagina. Once your eggs have been collected, you will be given medications in the form of suppositories, injections, or gels to help prepare the endometrium for the transfer of the fetus. If your fetus is frozen, the suppository is prescribed a few days before the transfer, depending on the day of the fetus.
4) Fertilize the eggs
Your eggs are injected into your partner’s sperm or donated sperm and cultured in the laboratory for 20 to 16 hours after the signs of fertility. Those that are fertilized (called embryos) will grow in the laboratory incubator for 5 to 6 days. The embryologist will examine the embryos and select the best ones for transmission. Any remaining embryos of the right quality can be frozen for future use.
5) The stage of embryo transfer
If you are under 40, 1 or 2 embryos will be transferred, and if you are over 40, a maximum of 3 embryos may be transferred. The number of transferred embryos is limited due to the risks of multiple births. Your doctor may suggest that a fetus be transferred (SET). If he feels this is the best option for you. This procedure is similar to removing a cervical smear, a suitable tube (catheter) is guided by ultrasound and passed through the cervix, and the fetus is transferred to the uterus through the tube. This procedure is usually painless and does not require any sedation. But you may feel a little uncomfortable, because your bladder needs to be full during the ultrasound.
As your partner’s eggs are collected, will be asked to prepare a sample of your sperm. Washed, active and natural sperm will be separated from the sperm, with better quality. If you have frozen sperm, it must first be removed from the freezer, heated, and prepared in the same manner.
