The donor and the patient synchronise their cycles so that the eggs do not have to be frozen.
The gynaecologist chooses the best donors, has access to their photographs, their academic record and hobbies, as well as the outcome of their previous donations.
Non-anonymous / known donors
If you would like to carry out your treatment with a non-anonymous / known sperm or egg donor, please ask for further information. Please note that this cannot be carried out in Spain due to legal reasons, but we will address you to a clinic in another country.
The results regarding pregnancy rates depend fundamentally on the quality of the oocytes, the sperm, the In Vitro Fertilisation laboratory and the healthcare team. From 4 oocytes, generally what is achieved is that there are more frozen embryos left.
