A certain group of women exists that, in spite of still being of a fertile age, present a problem which impedes the regular production of ovules and, therefore, they have difficulty in the reproduction. These are women who have had their ovaries removed due to an illness, or the ovaries have stopped functioning (early menopause, age...).

For these women the only possibility of becoming pregnant is through the donation of ovules of another woman. These ovules are inseminated in vitro with the semen of the partner of the recipient and the resulting embryos are transferred to the uterus of the recipient. In this way the women who opt for the donation of ovules are not the genetic mothers, but they are the biological mothers.

• To be between 18 and 35 years old.

• To have a normal ovary function.

• Must not have any genetic illness in the family

• Gynaecological revision with normal cytology and ultrasonograph.

• Complete blood analysis:

Blood group and Rh, hemogram, biochemistry, serologies (VIH, VHC, HbsAg, RPR), hormonal and karyotype analysis.

According to the present legislation, Law 35/1988 and the Royal Decree 412/1996:

• The donation of gametes for the objectives authorised by this Law is a free, formal and secret contract between the donor and the authorised Centre which will be formalised in writing.

• The donation will never have a lucrative or commercial character. However, in 1998, the National Commission for Human Assisted Reproduction considered, in their first report, that the existence of problems due to travel and loss of time justified an economic compensation without violating the gratis principle expressed in the Law 35/1988 and the Royal Decree 413/1996.

• The donation will be anonymous and the data of the donor’s identity will be kept in the most absolute secrecy.

• The choice of the donor will be the responsibility of the medical team. It is necessary to guarantee that the donor has the maximum phenotypic similarity and the maximum possibilities of compatibility with the recipient.

• The authorised Centres and the National Registry will control and make sure that no more than six children are born from the same donor.
