Hot news: great success rate attained in donor egg treatment
The usual success rate in egg donation procedure varies around 50%. Still there are features that may boost the possibility of success. The first one is the professionalism of the medical crew. The second is the quality of the donored eggs. If the donors are healthy the success chances increases greatly. And the final point is the usage of the best technologies. Just a small amount facilities offer all the three pros. One of them is AVA-Peter, a Russian-Finnish fertility center in Saint Petersburg. The following describes process they execute. This made them able to reach a 70% success rate in egg donation in first half of 2009.
Egg donation involves the first one is called an an egg donor and second is called an egg recipient. The egg donor goes through IVF procedures to make her ovaries eggs. The cells are then inseminated in the medical laboratory by the semen of the egg recipient's husband or partner (or a sperm donor). Theinseminated eggs are called embryos, and a single one or two of them are inserted back into the uterus of the egg recipient to produce a pregnancy.
Differences between IVF and IVF with egg donation
The main difference between 'standard IVF' and 'egg donation IVF' is that an extra person is needed to make a pregnancy. This woman is the egg donor, whose eggs are used if the potential mother (the egg recipient) cannot utilize her own eggsfor medical reasons to get pregnant. The subsequent is a thorough explanation of all the treatment stages.
Synchronising the menstrual cycles
Both the egg donor & the egg recipient should be at the start of their menstrual cycles in order to begin egg donation process. If you no longer have a ordered menstrual cycle, we can have it start at the right time.This is done by prescribing contraceptive medicationto both the donor and the recipient according to the decided plan. The medication are finished on the same day by both the donor and the recipient, leading to a 'withdrawal bleed' in both ladies.
The egg donor's treatment
After the egg donor's period starts, she has an ultrasound inspection of the uterus and the ovaries to make sure the ovaries are inactive and the uterine membrane is thin. Your egg donor then takes medication to stimulate her ovaries in forming eggs. After 10 days, she uses an additional hormone to make the egg cells prepared for collection. Egg harvesting is made by aspirating the cells from the follicles by a needle incerted into the ovary through the vagina. Her task is now over.
The egg recipient's treatment
Egg recipients may or may not still have a normal menstrual cycle. Once the period is started by the pills, you may undertake one or two additional injections of a 'down-regulating' medicine to guarantee finest synchronisation with your donor. Usually, you will after have a examination to check that the membrane of your uterus is thin enough and that there are no ulcers right before the start of the treatment cycle. This includes taking oestrogen tablets, cream and patches to build up your uterus lining again. Five days before the intended day for Embryo Transfer, you begin taking progesterone besides oestrogen.
Inspermation and embryo transfer
The donor eggs harvested are inspermated with the semen of the male partner or a donor. They are grown in our lab for three or (more frequently) five days. For the period of this step, they keep on dividing and develop. At five days old, embryos are called as| blastocysts. By this stage, our professional embryologists are able to estimate which embryos are of the most promising quality. On the day of embryo transfer, a single or a pair of the best embryos are moved through the cervical tube incide the egg recipient's womb using a thin, elastic plastic catheter. This process is almost always short and provides no pain.
Following the embryo incertion, you continue using oestrogen and progesterone tablets for two weeks and afterwards take a pregnancy test. If the test is positive, you should go through an examination to verify the pregnancy two weeks after. If a 'fetal pole' is seen on the scan, this grants clinical proof of your pregnancy.
At AVA-Peter, we reached a 60% success rate in 2008. It was the confirmed clinical pregnancy ratio after transfer of 2 fresh (not frozen) embryos at the 5-day-old blastocyst development phase. An amount of babies born through egg donation is rising each year as more women know about this type of treatment.
