Pregnancy through egg donation: the most effective technique

egg donation

The age is the most known factor that negatively affects women’s fertility. When it increases, the ovary looses the ability to produce healthy eggs in order to achieve the pregnancy. Maternity is always more postponed due to several reasons and in many cases In Vitro Fertilization with own eggs fails. Thanks to advances in assisted reproduction, these women can achieve pregnancy by using donated eggs, which is the most effective assisted reproductive alternative.

The IVF by Egg donation is especially addressed to those patients who experienced a decrease in the ovarian reserve and in the quality of eggs or for those women who had more than 2 failed In vitro fertilization cycles (premature ovarian failure, genetic disorders).

High pregnancy rate by egg donation

There is a high pregnancy rate in IVF by Egg donation. Particularly, the probability of achieving the pregnancy with the first cycle is 60% on average and it can reach up to 90% in the following attempts. The possibility is high due to three factors:

  1. Age of the donor: due to the influence of the age on egg quality, the donors must be aged 18-30. As the age increases, the quantity and quality of the oocytes decreases considerably.
  2. Quality of donated oocytes: the eggs retrieved from the donor are of high quality; they are carefully selected after subjecting them to a previous fertility study which ensures that the donor is provided with ideal quality oocytes. According to the assisted reproduction team, the most viable oocytes will be fertilized.
  3. Optimal physical and immunological health of the donor: in order to check that the donor is not affected by any genetic, congenital and inherited disease, she is subjected to medical tests to demonstrate that she is in good physical and mental health.  These tests include the following:

 Routine blood test for liver and renal function as well as coagulation

  • Serology study to rule out sexually transmitted diseases
  • Pap smear tests and Genitourinary cultures
  • Ultrasound scan
  • Genetic study: Karyotype, cystic fibrosis test to rule out possible inherited diseases
  • Interview with Psychologists specialized in assisted reproduction
