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 MEDICAL HISTORY (anamnesis)

MEDICAL EXAMINATION

GYNAECOLOGICAL ASSESSMENT

  • Cytology
  • Ultrasound
  • Breast examination

PSYCHOLOGICAL ASSESSMENT

  • Consists of a psychological test and a consultation with our team of psychologists, which help rule out conditions that may affect the donor's mental health.

GENETIC CARRIER SCREENING
(recessive monogenic disorders)

All our donors have undergone screening for recessive monogenic disorders. Only oocytes with a compatible genetic match for the assigned patient and/or without recessive mutations recommended for screening by the SEF are sent.

Egg bank donors are never carriers of fragile X syndrome or of the X-linked conditions assessed by the carrier screening test.

SERUM SAMPLE STORAGE

We are committed and responsible for retaining a blood sample from every donor until 2 years have elapsed since the last embryo transfer performed using her oocytes.

Any changes to the legal regulations governing the basic tests required for donor screening will be immediately incorporated into the tests performed at our egg bank.

LABORATORY TESTS

COMPLETE BLOOD COUNT:

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

COAGULATION:

  • Prothrombin time

BIOCHEMISTRY:

  • Glucose
  • G6PDH
  • Cholesterol
  • Triglycerides
  • GPT
  • Urea

SEROLOGY:

  • HIV (anti-HIV-1, HIV-2, p24)
  • HBV (anti-HBsAg, HBcAg)
  • HCV
  • Syphilis (RPR and TPHA)
  • Rubella
  • Toxoplasmosis

(*) When indicated, testing also includes: Chagas disease, Zika and CMV (IgG, IgM and avidity).

PCR (TMA):

  • Qualitative detection of HCV, HBV, HIV-1 and HIV-2

GENETICS:

  • Peripheral blood karyotype

GENETIC MATCHING

Allows the genetic information of the oocyte donor to be compared with the genetic data of the recipient's male partner.

This genetic compatibility screening compares more than 300 genetic disorders with the aim of preventing the transmission of these recessive monogenic disorders to offspring.

All our donors are screened using the qCarrier® Test (qGenomics). However, if requested by the collaborating clinic, the donor can also undergo the genetic test required for the 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.
