History of how can be IVF performed?
IVF as a technique was developed in the 1970s. This technique may differ slightly from clinic to clinic but the base of this technique is always the same everywhere.
Step by step how can be IVF performed for women
Step 1: suppress the monthly cycle
The doctor will give you a drug that will suppress your natural monthly menstrual cycle. This drug may be a daily injection that the caregivers will teach you how to give yourself, or the drug may be a nasal spray. This therapy may last about two weeks.
Step 2: boost the egg supply
You have already suppressed your natural monthly cycle, now it is time to take a fertility hormone called FSH (follicle stimulating hormone). It is a gonadotropin, which is another daily injection that you are going to give yourself for the next 12 days. It may also vary depending from the response; the FSH increases the number of eggs your ovaries produce. Increased production means that more eggs can be collected and fertilized. More eggs, more embryos to choose and use in your treatment.
Step 3: the progress
During the process the clinic will keep an eye of every progress that you make, this may include vaginal ultrasound scans to monitor your ovaries and blood tests if needed. Your final hormone injection will be 34-36 hours before your eggs due to be collected; this final injection will help your eggs to mature.
Step 4: Collecting the eggs
You will be sedated during this procedure. Your eggs will be collected under ultrasound guidance; the doctor will insert a needle through the vagina and into each ovary. Through this needle the eggs are then collected.
Step 5: Fertilization
The eggs are now collected and they have to be mixed with your partner’s or your donor’s sperm in the laboratory. 16-20 hours have to pass after they are mixed so they can check if any have been fertilized. In cases where the sperm are few or weak, each egg has to be injected individually with a single sperm. This procedure is called intra-cytoplasmic sperm injection (ICSI).
The cells are now fertilized and they need to continue to grow in the laboratory for one to five days before being transferred into the womb. The doctor will pick the best one or two embryos for transfer.
Step 6: Embryo transfer
Before the treatment you should discuss with your doctor about the number of embryo to be replaced. For women under the age of 37, in their first IVF usually have a single embryo transfer. If there are no-top quality embryos available and it is your second IVF, doctors should consider using only two embryos. Having a multiple embryo transfers may result into a multiple pregnancy and birth.
How can be IVF performed- for men
After your partner’s eggs have been collected, you’ll be asked to produce a fresh sample of sperm. The doctors are going to take the sample of sperm, wash it and spun at a high speed. This is done in order the healthier and most active sperm to be selected.
