Donor Selection

The selected egg donors are healthy women between 18 and 29 years of age who donate eggs voluntarily, anonymously and altruistically.
The donor selection process is very rigorous. As a general rule, one out of every three candidates is accepted.
The selection protocol consists of the following steps:


In-depth psychometric interview and evaluation to rule out inappropriate habits or psychiatric or psychological disorders.


Detailed personal and family medical history to rule out heredofamilial diseases.
  • Evaluation of phenotypic characteristics, personal and social habits.
  • Provision of informed consent for egg donation .
  • Photographic record for Procreareggbank’s internal and confidential medical use.
  • Physical, genital and mammary examination with cervicovaginal cytology.
  • Transvaginal Ultrasound


Antral follicle count and antimullerian hormone assessment if applicable.

      Note: it is possible to perform genetic matching with bank or partner semen.


The oocytes are vitrified using the KITAZATO method.
