Our donor candidates undergo a strict protocol for their selection through different stages, which is under continuous revision and improvement. We introduce new screening tests and improve existing ones in order to offer the highest success rates for fullfulling a woman´s dream, not only of achieving motherhood but also having a healthy baby.
We do not only perform the tests required by Spanish law but complete the study according to recommendations of International Scientific Societies
- 95 % of our donors are university students
- 99% of donors are Spanish nationals.
- Aged between 18 – 35 years old
- Average age: 25 years old
Oocytes Donors Selection
An Individual and family medical history is carried out tracing back to grandparents, to rule out hereditary diseases, according to Spanish Law 9/2014 and RD 412/1996.
We add an evaluation the psychological history of the donor and his family environment as recommended by Spanish Society for Fertility (SEF).
Since the law does not address the exclusion criteria, we proceeded back in 2007 , with the help of various experts in each subject and in the context of Ceifer Classroom Training, to the publication of the book «THOUGHTS ON THE EVALUATION OF GAMETE AND EMBRYO DONORS«. This study provides support for the selection of donors.
- A general physical examination is performed.
- Cytology:
- Tests for Chlamydia
- Microbiological culture: enterobacteria, gardenerella, neissseria gonorrehoeae, urogenital mycoplasmas and fungi.
STD serology is initially performed at the donor selection stage, and is renewed quarterly when oocyte donations are made.

• PCR Analysis: HIV 1, HIV 2, Hepatitis B and Hepatitis C the day when follicule extraction takes place.
• Serum bank: we keep serum samples from the day when oocytes where extracted, to allow for a retrospective study measuring the levels of various biochemical markers at the moment of the oocytes extraction.

We have implemented a protocol for the study of genetic diseases at our sperm bank which is unique worldwide.
CEIFER Protocol for genetic studies allows discarding potential donors who are carriers of the most prevalent genetic diseases, specifically those of autosomal recessive nature that manifest only in the offspring.
Chromosome Study – Kariotype
Only donor candidates with normal kariotype are accepted. Additionally candidates with polymorphic karyotypes are discarded since they offer lower results for assisted reproduction techniques.
Carriers of autosomal recessive monogenic diseases
Genetic studies are carried out to eliminate donor candidates who are carriers of the most prevalent autosomal recessive monogenic diseases in our environment (Mediterranean area of Europe):
| Disease | Gene |
|---|---|
| Spinal Muscular Atrophy | SMN1 |
| Cystic Fibrosis | CFTR View Table 1* |
| X-chromosome linked diseases (57) | Duchenne, Hemophilia A - B, Fabry, Pompe, G6PD, AR, mental retardation...* View Table 2* |
To reduce the risk of offspring affected by these and other diseases, it is recommended to perform Genetic Matching (more information below in DNA Bank and Genetic Matching)
DNA BANK
From 2005 on CEIFER Biobanco has a sperm donor DNA bank. In this way, in case of genetic disease arising in the offspring, we can carry out the pertinent genetic studies.
CEIFER Biobanco thus has a global vision and the most advanced technology for:
- Screening for genetic disorders in live birth cases where offspring is affected.
- Implement screening tests for new genetic disorders in our screening protocols.
GENETIC MATCHING
Genetic matching allows the genetic information from the donor woman to be compared with that of the male partner of the recipient woman in order to avoid the transmission of autosomal recessive genetic diseases.
To this end, a mass sequencing test against more than 307 genes related to monogenic recessive diseases is carried out. This analysis is performed using the most modern techniques of mass sequencing (Next Generation Sequencing – NGS).
Among these 307 genes screened there are variants with a particularly high incidence in the Mediterranean area. The results from our donor samples are compared with the similar genetic study performed on the recipient woman, selecting a suitable donor so that sperm donor and the receiving woman do not share mutations in the same genes.
(The genetic matching protocol does not eliminate the risk in the offspring of being affected or being a carrier of recessive diseases, even if it is one of the diseases studied. Its objective is the significant reduction of risks, depending on the disease object of study).

Vitrification
We use Kitasato vitrification medium, approved by the competent authority (CE label) for use with human specimens.
- This allows us to meet the highest recommendations issued by international organizations related to banks of human tissues and cells (EU Directive 2004/23/EC and Law 9/2014).
- We ensure the traceability of the process, allowing at any time to know the batch and obtaining information to identify the problem.
- Ensures sterility of our vitrification process.
Our vitrification protocol makes use of CryoTop® Method, approved by the competent authority (EU label) for use in human specimens.
CryoTop® vitrification method is highly effective for oocytes and embryos cryopreservation providing:
- Excelent survival rate for oocytes.
- Fertilization.
- Embryonic development (optimum cleavage-stage results).
- Pregnancy.
Vitrification containers are identified with a UNIQUE CODE that incorporates a serial code and donor identification number. This allows for traceability of each container with vitrified oocytes.
- Identification of every container with the donor identification code to prevent confusion between containers from different donors.
- Imposibility for external manipulation of the code, as it is not possible to remove without destruction of the label.
- Easy identification by the receiving Reproductive Center.
Containers holding oocytes are stored inside containers filled with liquid nitrogen, temperature regulated at -196 °C.
- Immersion into liquid nitrogen is the best method for human oocyte and ovarian tissue cryopreservation.
- Our containers are 24h monitored for temperature and filling levels.
Transportation
We only use approved certified containers. Liquid nitrogen travels absorbed into porous material.
- Approved for shipping biological samples
- Approved for transport on land, by ship and air freight shipping
- Extra security with no risk of spillage during transportation
PACKAGING
Our delivery system makes possible to have a sample available at destination within 24h.
