Egg Donation
What is it?
Is a the process by which a woman provides one or several eggs and it is carried out in an anonymous, voluntary, and altruist form, giving of eggs from one woman to another, in order to that she can have a child.
When it is used?
The donation is an adequate option in women with blocked fallopian tubes, menopausal, failure of ovulating after chemotherapy or radiation therapy, malfunctioning gonads (ovaries), advanced age, poor quality eggs, genetic problems, etc.
What people can donate?
The donors of eggs are healthy young people, they also have comply to a series of requirements and health checks to be able to be included in a program of donation.
What is the procedure?
For the recipient the risks are the same as in a normal pregnancy. If the recipients are over 45 years old a health check will be carried out at the beginning of the process.
What are the risks?
The most habitual risks can be: Multiple pregnancies, nevertheless this risk is practically nil since in practice only one or two embryos are transferred, because this has been seen to have the best rate of success. Ovarian Hyperstimulation Syndrome: Is a complication from some forms of fertility medications, to minimise the risk of this we control it with regular ultrasounds and tests. Ectopic pregnancy: . Occasionally the embryo implants into the Fallopian tube instead of the uterus, creating an ectopic pregnancy, commonly known as a "tubal pregnancy". This only happens in about 3% of cases, because of this our centre carries out ultrasounds, and although we can not eliminate the risk, in this way we assure ourselves that we place the embryos in the adequate place. The risks of the sedation-anesthesia: During all the intervention (10-15 minutes) the process is controlled by the anaesthetist, and the patient will be monitored during all the intervention.
Rate of success?
The rate of success in patients less than 35 years old is around the 50%mark, from 35 years old upwards the probability diminishes with age. Nevertheless, this technique is also utilised with the donation of eggs and can bring rates of pregnancy close to the 70% mark, in this way the limitations that involves age are not as big a factor.
