WHY DONATED EGGS ARE NEEDED

WHY DONATED EGGS ARE NEEDED

Donated eggs are uused in the treatment of reproduction where a woman cannot use her own: Here are some of the reasons why a woman may not use her eggs:

1. When she cannot become pregnant with conventional assisted reproduction due to repeated failures in In Vitro Fertilization: low responders: those that do not respond to ovary stimulation; repeated failure of fertilization with ICSI; Repeated failure with the implantation of embryos (failure of repeated gestation).

2. When the ovary stops producing eggs for natural reasons in patients older than 40 years (menopause) and younger (early ovarian failure).

3. Women who despite ovulating, the quality of the eggs is defective.

4. Women with repeated abortions, when there is a family background of hereditary disease that the woman could transmit in the case of using her own eggs, which makes donation preferable. The causes that cause chromosome alterations responsible for Downs Syndrome are not exactly known although it is statistically related to a maternal age more than 35 years old.

5. When the patient has had her two ovaries removed, or has undergone chemotherapy or radiotherapy.

Characteristics for the donation of eggs

Women who donate eggs should have various characteristics, such as be less than 35 years old, have a negative history of genetically transmitted diseases, a good intellectual level and psychological stability.

Also, studies are made to check their good physical and mental state, which includes chromosome analysis (karyotype), negative results for sexually transmitted diseases such as AIDS and hepatitis and psychological evaluation, among other things. Of course, the main physical characteristics of donor and receptor should coincide.

The donors receive a treatment leading to the formation of various eggs in a same cycle.

The donors are evaluated by ultrasound on repeated occasions to verify their number and size of the follicles that the eggs contain. When they are mature, they are extracted by means of ultrasound-guided vaginal puncture in the OR and with soft anesthesia or sedation.

Once the eggs have been recovered, they go to the Reproduction laboratory for their identification, culture or insemination with the semen of the partner of the receptor. They will stay in the laboratory for between two and five days inside the incubator to assess their development.

The transfer of embryos is a simple procedure that does not require anesthesia.

The probability of getting pregnant with this technique are very encouraging, as between 40 and 50% of the women achieve pregnancy at the first attempt or transference, if they are not successful the first time, the procedure can be made again without any limits. After four attempts most have a happy ending.

In our clinic you are informed of the analysis as well as the information that you should give to be a receptor of eggs:

a prior medical and gynecological record as well as some report cases of previous treatments in other centres.
Updated serologies of Hepatitis B and C, syphilis amd AIDS from both partners.
Blood groups and Rh of both partners.
Fill in and sign the request and informed consent for In-Vitro Fertilization with egg donation.
