Hot news: great success rate attained in egg donation treatment
The ordinary success rate in egg donation treatment varies at 50%. Anyway there are features that may boost the chance of success. The first to mention is the experience of the medical crew. The second is the quality of the donored egg cells. If the donors are parents themselves the success possibility improves greatly. And the final point is the usage of the newest technologies. Just a minority clinics offer all advantages. One of them is AVA-Peter, a Russian-Finnish fertility clinics in Saint Petersburg. The next describes treatment they perform. This allowed them to attain a 70% success rate in egg donation in first half of 2009.
Egg donation involves two persons one is called an egg donor and second is called an egg recipient. The egg donor goes through IVF treatment to make her organism eggs. These are then inseminated in the medical laboratory by the sperm of the egg recipient's husband partner (or a sperm donor). Thefertilised eggs become embryos, and a single one or a pair of them are inserted back into the womb of the egg recipient to form a pregnancy.
Differences between IVF and IVF with egg donation
The major difference between 'typical IVF' and 'egg donation IVF' is that an extra person is necessary to help form a pregnancy. This person is the egg donor, whose eggs are used when the would-be mother (the egg recipient) cannot utilize her own eggsfor medical reasons to get pregnant. The following is a total explanation of all the process stages.
Synchronising the menstrual cycles
Both the egg donor & the egg recipient need to be at the beginning of their menstrual cycles which is needed to launch egg donation treatment process. In case if no longer have a usual menstrual cycle, we can have it induced at the tijme we need.This is performed by prescribing birth control medicationto the donor and the recipient along with the decided plan. The tablets are stopped on the same date by both the donor the recipient, resulting in a 'withdrawal bleed' in both ladies.
The egg donor's treatment
After the egg donor's period starts, she has an ultrasound diagnostics of the womb and the ovaries to assure the ovaries are idle and the uterine membrane is thin enough. Your egg donor then undertakes medication to stimulate her ovaries to produce eggs. After about 10 days, she uses an extra hormone to make the eggs fit for harvesting. Egg gathering is made by aspirating the egg cells from the follicles with a needle introduced into the ovary through the vagina. Her mission is now over.
The egg recipient's treatment
Egg recipients may or may not have a usual menstrual cycle. After the period is started by the pills, you may undertake one or sometimes two additional injections of a 'down-regulating' drug to ensure finest synchronisation with your donor. Usually, you will after have a scan to check that the lining of your uterus is thin and that there are no ulcers right before starting the treatment course. This involves taking oestrogen pills, patches or cream to build up your womb lining again. Five days before the planned date for Embryo Transfer, you start taking progesterone in addition to oestrogen.
Fertilisation and embryo transfer
The donor eggs collected are inseminated with the sperm of the your partner or a sperm donor. They are developed under control in our lab for three or (more frequently) five days. For the period of this step, they carry on dividing and develop. At five days old, embryos become| blastocysts. By this part, our experienced embryologists are able to estimate which embryos are of the most promising quality. On the date of embryo transfer, one or two of the best embryos are introduced through the cervical tube incide the egg recipient's womb using a threadlike, elastic plastic catheter. This procedure is usually short and provides no pain.
Following the embryo incertion, you go on with taking oestrogen and progesterone tablets for two weeks and afterwards take a pregnancy test. If the test shows positive result, you should have a scan to confirm the pregnancy two weeks later. If a 'fetal pole' is visible on the scan, this provides clinical proof of your pregnancy.
At AVA-Peter, we had a 60% success ratio in 2008. It was the confirmed clinical pregnancy ratio after transfer of 2 fresh (not frozen) embryos at the 5-day-old blastocyst growth stage. An amount of babies conceived through egg donation is rising each year as more women become acquainted with this sort of treatment.
