with Egg Donation
In Vitro Fertilisation (IVF) is one of the most widely used techniques in Assisted Reproduction. It consists of fertilising the oocyte with the sperm in the laboratory and then transferring the resulting embryo or embryos to the uterus of the patient.
With the EGG4 programme we guarantee the obtention of a minimum of four mature oocytes of optimum quality. It offers a pregnancy rate per cycle of 85% and an economic cost, lower than a conventional Donor Egg IVF cycle.
For those patients whose eggs are not of sufficient quality to achieve an evolving pregnancy, either because of their age or other circumstances (menopause, early ovarian failure, genetic causes, etc.)
Pregnancy rate per cycle refers to pregnancies achieved with embryos generated in the same oocyte retrieval or pick-up. This includes the transfer of fresh embryos and possible frozen embryos. In the case of Egg4 IVF with donor eggs, our pregnancy rate is 85%.
These excellent results have been achieved by transferring a single embryo in 90% of the treatments. In this way, we have shown that the transfer of a single blastocyst (embryo on its fifth day of development) improves success rates.
How does it work?
Our Donors: the perfect "Match"
In Barcelona, and as a project of Institut Marquès, we have our sperm bank with more than 2,000 premium donors. They are anonymous donors, as the Spanish law 14/2006 of May 14 on assisted human reproduction techniques establishes that donation must be anonymous, voluntary, informed and unpaid.
As we have our own sperm bank, we know the donors and select only the best. They are young people who decide to donate to help other people to build a family and who must undergo exhaustive medical and psychological tests. We also have all the phenotypes to find the most suitable donor for each case. It is the doctor himself who will be in charge of choosing the best fitting sperm donor for you, taking into account your physical features and the hereditary traits of your personality. We look for the perfect match.
If you prefer to personally choose your donor (non-anonymous donor) or do your treatment with the sperm of a family member or friend (known donor) we can help you, we collaborate with the best clinics.
