Your egg bank

The donors at our egg bank are carefully selected women, with an average age of 25.

We analyse whether they have good physical and mental health and do not suffer from any genetic or sexual transmitted disease. For this reason they are subjected to a thorough selection process, with exhaustive gynaecological, psychological, serological and genetic tests.

A very high percentage of oocyte donors are discarded, and we only accept donors offering full guarantees and the highest success rates.

Our goal is and always will be a pregnancy and a healthy baby.

What tests do we perform on our donors?

BASIC TESTS

PERSONAL AND FAMILY CLINICAL HISTORY (anamnesis)

MEDICAL EXAMINATION

GYNAECOLOGICAL ASSESSMENT

  • Cytology
  • Ultrasound scan
  • Breast examination

PSYCHOLOGICAL ASSESSMENT

  • Consisting of a psychological test and a visit from our team of psychologists, enabling us to rule out any pathologies affecting their mental health.

GENETIC CARRIER TEST
(RECESSIVE MONOGENIC DISEASES)

All OXX bank oocyte donors are subjected to the genetic test on recessive diseases in order to significantly minimise the risk of their transmission to any offspring.

The genetic test used is the qCarrier® Test (qGenomics), which, by means of NGS, analyses more than 4,000 mutations potentially responsible for around 300 recessive genetic diseases. The diseases analysed include cystic fibrosis, fragile X syndrome, spinal muscular atrophy, thalassemias, neonatal diabetes, congenital hypothyroidism, etc.

Upon the basis of the results obtained, we exclude oocyte donor candidates who are carriers of:

  • Cystic fibrosis
  • SMN1
  • Diseases linked to the X chromosome (fragile X, haemophilia, etc.).

SERUM BANK

Our commitment and responsibility in retaining a blood sample of all the donors until two years after the last embryo transfer carried out with their oocytes.

BLOOD TEST

HAEMOGRAM

  • Haemogram
  • Platelets
  • Rh factor (D)
  • Blood group

SEROLOGY

  • Ag HBs
  • Ac HBs
  • Ac HBc (IgG + IgM)
  • CMV (IgG + IgM)
  • HIV 1 + HIV 2
  • Ac VHC
  • RPR
  • HTLV I - II

BIOCHEMISTRY

  • Creatinine
  • Urea
  • ALT / GPT
  • ALT / GOT
  • Glucose
  • Triglycerides
  • Total cholesterol
  • HDL

COAGULATION

  • Prothrombin time

GENETICS

  • Kariotype

GENETIC MATCHING

This enables us to compare the genetic information of the oocyte donor and the data of the recipient’s male partner.

This genetic compatibility study compares more than 300 genetic diseases in order to prevent the transmission of these recessive monogenic diseases to any offspring.

All our donors are examined by the qCarrier® Test (qGenomics), but if the partner centre so requires, the donor may also undergo the genetic tests required in each specific case.

Shipping and delivery times

In OXX bank shipments are made in containers of absorbed liquid nitrogen approved for land, air or sea transport, which ensure the maintenance of the proper temperature throughout the journey. Shipments are door-to-door, handled by our specialized carriers to guarantee the custody and traceability of the samples.
