Egg and Sperm Donations
An egg donation offers all women the possibility of pregnancy because they are unable to produce their own eggs for conception even though they have a healthy uterus. This applies to women in early menopause, women without both ovaries, carriers of hereditary chromosomal anomalies, and all those who respond insufficiently to ovarian stimulation and have been unsuccessful in their various IVF attempts.
The process is similar to that of an IVF cycle wherein the donor is stimulated and goes through egg retrieval. The only difference being once the donor eggs are collected, they are fertilized with the sperm of the recipient’s partner and the best embryos are transferred to the recipient. In order to do this, the donor’s cycle is synchronized with the recipient cycle so that the recipient’s uterus is ready to receive the embryos when they are ready to be transferred. To prepare the uterus, the recipient takes medication to enable it to achieve a thickness sufficient for embryo implantation. Any remaining embryos that are viable are frozen for future use.
Selecting an egg donor is a long and rigorous process and before any donor can be selected, they are given a battery of physical, medical and psychological tests, stipulated by law, to eliminate the possibility of congenital diseases, malformations and sexually transmitted diseases.
There is no waiting list for egg donations and it is possible to have an appropriate donor within 1-2 months from your first appointment. We select one donor per patient, and consider nationality, race, hair color, eye color, blood type, and other characteristics of the donor.
Egg donations produce excellent success rates and are completely anonymous, by law, in Spain.
Couples need donor sperm when the male partner produces very few, abnormal, or no sperm at all and is recommended for men who have had a vasectomy, have undergone cancer treatment which may have altered sperm production, are completely infertile due to a previous illness, or carry a genetic or contagious disease. It is also an option for single women and lesbian couples.
Donor sperm can be used through artificial insemination or as part of an IVF procedure. If it is used via insemination, the sperm is injected directly into the woman’s uterus and timed with her ovulation. If it is used during an IVF cycle, the sperm is used to create an embryo in the laboratory and then transferred into the uterus.
Donors are chosen based on their physical characteristics and blood types and careful screening procedures are carried out them to eliminate the possibility of severe genetic alterations that can be transmitted to descendants, malformations and sexually transmitted diseases to ensure that the sperm is safe to use.
Semen donations are completely anonymous, by law, in Spain.
