Assisted Reproductive Treatments Receipt of oocyte (Oocyte Donation Program)

The Oocyte Donation program enables an increasing number of women to realize their dream of motherhood. Please contact us.

The receipt of oocyte is a reproduction technique during which the female gamete (oocyte) is brought by a woman (the donor) other than the woman who will receive the resulting embryo (the receiver). The pregnancy rate obtained exceeds the other Assisted Reproduction Techniques.

The oocyte donation is recommended in the following cases:

  • Close to menopause
  • Ovary dysfunction
  • Women carrying genetic diseases or chromosome alterations preventing a DGP
  • Lack of ovary stimulation response (occult ovary dysfunction)
  • Repeated failures of In Vitro Fertilization.
  • Repeated abortions
  • Women more than 40 years old

Selection of the donor:

The donors are young women wanting to donate their oocytes selflessly within the following conditions:

  • Age between 18 and 30 years
  • Medical file exempt from all genetic diseases
  • Normal genetic Karyotope
  • Blood analysis not showing any infectious disease
  • Good psychophysical state
  • Good response during the In Vitro Fertilization cycle

The donor is designated by the medical and biological team based on genetic factors (height, skin color, color of eyes, color and type of hair), and the blood group and the Rh factor.

Preparation of the donor:

Once the oocyte donation program conditions are fulfilled, the In Vitro Fertilization with ICSI-IMSI can start.

Preparation of the receiver:

As opposed to the other assisted reproductive treatments, the receivers are only subjected to a simple treatment, i.e. the appropriate preparation of the endometrium (uterus cavity where the future embryos will be implanted). In general, the treatment is done orally and only one or two ultrasound checks are required.

The embryo is transferred as in the other cycles of the In Vitro Fertilization.

Resultados:

The pregnancy rate by cycle exceeds 60%, because the implantation depends on the quality of the embryo which depends on the quality of the oocyte; the oocyte is directly linked to the age of the donor.

At the end of 4 cycles of oocyte donation, the success rate reaches 94%.

Receipt of Oocyte Program:

Our Receipt of Oocyte program is very simple. It requires a first visit in our assisted reproduction center where all the important clinical data will be collected to apply the treatment. In case of couples, we freeze the sperm that should be used during the oocyte donation cycle.

The patient is subjected to the treatment (who requires only one or two ultrasound checks).

The designated donor undergoes an In Vitro Fertilization cycle. In the laboratory, we therefore perform the ICSI-IMSI techniques to generate the embryos.

During the second visit, we proceed to the transfer of embryos.

The oocyte donation is strictly legal and anonymous in Spain. In our assisted reproduction clinic, the waiting period to receive an oocyte from a donor is approximately 3 weeks.
