Good news: great pregnancy rate attained in donor egg treatment
September 4th, 2009
The expected success rate in egg donation process varies about 50%. Of course there are options that may boost the possibility of success. First of all the experience of the medical team. The second to mark is the condition of the donored ovum. If the donors are healthy the success chances rises noticeably. And the final point is the usage of the most innovative technologies. Just some facilities offer all benefits. One of them is AVA-Peter, a Russian fertility clinics in Saint Petersburg. The following describes treatment they execute. This made them able to get a 70% success rate in egg cell donation in first half of 2009.
Egg donation involves one is called an egg donor and an egg recipient. The egg donor undergoes IVF procedures to make her ovaries egg cells. The eggs are afterwards inseminated in the laboratory by the sperm of the egg recipient's husband partner (or a sperm donor). Thefertilised eggs are called embryos, and one or two of them are introduced back into the uterus of the egg recipient to form a pregnancy.
Differences between IVF and IVF with egg donation
The key difference between 'normal IVF' and 'egg donation IVF' is that one more person is required to help create a pregnancy. This person is the egg donor, whose eggs are used in case if the potential mother (the egg recipient) cannot make use of her own eggs to get pregnant. The following is a full description of all the process stages.
Synchronising the menstrual cycles
Both the egg donor and the egg recipient must be at the beginning of their menstrual cycles which is needed to launch egg donation treatment process. In case if no longer have a regular menstrual cycle, we can have it start at the right time.This is made by prescribing birth control medicationto both the donor and the recipient according to the settled plan. The tablets are stopped on the same day by both the donor the recipient, resulting in a 'withdrawal bleed' in both women.
The egg donor's treatment
As soon as the egg donor's period begins, she has an ultrasound examination of the womb and the ovaries to assure the ovaries are inactive and the uterine membrane is thin. Your egg donor afterwards takes medication to stimulate her ovaries to form eggs. After about 10 days, she takes one more hormone to make the egg cells fit for collection. Egg harvesting is performed by aspirating the eggs from the follicles via a needle introduced into the ovary via the vagina. Her mission is now over.
The egg recipient's treatment
Egg recipients may or may not still have a normal menstrual cycle. After the period is induced by the pills, you may have one or sometimes two extra injections of a 'down-regulating' drug to guarantee optimal synchronisation with your donor. In most cases, you will after have a examination to check that the lining of your womb is thin and that there are no ulcers right before the start of the treatment course. This involves taking oestrogen tablets, cream and patches to build up your uterus lining . Five days before the intended day for Embryo Transfer, you begin taking progesterone in addition to oestrogen.
Insemination and embryo transfer
The donor eggs taken are fertilised with the sperm of the male partner or a donor. They are grown in our laboratory for three or (more usually) five days. During this stage, they go on with dividing and develop. At five days old, embryos become| blastocysts. By this step, our experienced embryologists can determine which embryos are of the most viable quality. On the day of embryo transfer, one or two of the excellent quality embryos are introduced through the cervical tube incide the egg recipient's uterus using a thin, soft plastic catheter. This process is in most cases short and provides no pain.
Following the embryo transfer, you go on with using oestrogen and progesterone medication for two weeks and then take a pregnancy test. If the test shows positive result, you should undergo an inspection to confirm the pregnancy two weeks later. If a 'fetal pole' is noticeable on the scan, this grants clinical confirmation of your pregnancy.
At AVA-Peter, we achieved a 60% success rate in 2008. This was the proven clinical pregnancy percentage after replacing 2 fresh embryos at the 5-day-old blastocyst development stage. An amount of children born through egg donation is becoming higher each year as more infertile women know about this form of treatment.
