The regular success rate in egg donation treatment varies at 50%. But there are factors that may boost the possibility of success. The first to mention is the experience of the doctors. The second to mark is the quality of the donored eggs. If the donors are healthy the success rates improves noticeably. And the last point is the usage of the newest technologies. Just some facilities offer all advantages. One of them is AVA-Peter, a Russian fertility clinics in Saint Petersburg. The next describes treatment they execute. This made them able to attain a 70% success rate in egg cell donation in first half of 2009.
Egg donation involves two persons the first one is called an an egg donor and second is called an egg recipient. The egg donor undergoes IVF process to make her ovaries egg cells. The cells are then inspermated in the medical laboratory by the sperm of the egg recipient's husband partner (or a sperm donor). Theinseminated eggs are called embryos, and a single one or two of them are introduced back into the womb of the egg recipient to form a pregnancy.
Differences between IVF and IVF with egg donation
The main difference between 'typical IVF' and 'egg donation IVF' is that an extra person is necessary to help produce a pregnancy. This is the egg donor, whose eggs are used if the would-be mother (the egg recipient) cannot use her own eggs to get pregnant. The next is a full explanation of all the programme steps.
Synchronising the menstrual cycles
The egg donor and the egg recipient are to be at the beginning of their menstrual cycles in order to begin egg donation procedures. In case if no longer have a usual menstrual cycle, we can have it induced at the tijme we need.This is made by prescribing birth control tabletsto the donor and the recipient in line with the settled plan. The medication are finished on the same date by both the donor the recipient, leading to a menstruation in both women.
The egg donor's treatment
Once the egg donor's period begins, she has an ultrasound inspection of the uterus and the ovaries to ensure the ovaries are inactive and the womb membrane is thin enough. Your egg donor afterwards takes medication to stimulate her ovaries to produce eggs. After about 10 days, she takes an extra hormone to make the eggs fit for harvesting. Egg collection is performed by aspirating the eggs from the follicles via 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 induced by the tablets, you may undertake one or in some cases two additional injections of a 'down-regulating' drug to make certain finest synchronisation with your donor. In most cases, you will afterwards have a scan to check that the lining of your womb is thin and that there are no ulcers right before the beginning of the treatment cycle. This includes taking oestrogen tablets, cream or patches to build up your uterus lining . Five days before the scheduled date for Embryo Transfer, you begin taking progesterone as well as oestrogen.
Insemination and embryo transfer
The donor eggs harvested are inspermated with the sperm of the male partner or a donor. They are grown in our laboratory for three or (more often) five days. For the duration of this step, they keep on dividing and grow. At five days old, embryos grow to be| blastocysts. By this stage, our expert embryologists are able to determine which embryos are of the best quality. On the day of embryo transfer, one or two of the best embryos are transported through the cervical canal into the egg recipient's womb using a threadlike, elastic plastic catheter. This procedure is usually fast and painless.
Following the embryo transfer, you carry on with using oestrogen and progesterone medication for two weeks and after the end of the course take a pregnancy test. If the test is positive, you must undergo an inspection to confirm the pregnancy two weeks after. If a 'fetal pole' is visible on the scan, this gives clinical proof of your pregnancy.
At AVA-Peter, we reached a 60% success ratio in 2008. This was the proven clinical pregnancy percentage after replacing 2 fresh embryos at the 5-day-old blastocyst growth phase. An amount of children conceived through egg donation is rising each year as more infertile ladies become aware of this form of treatment.
