How Many Donor-Egg Cycles Before Success?
In IVF treatments with donor eggs and/or sperm, success rates are higher if compared to cycles where own gametes (eggs and sperm) are used. This is due to the fact that donors are young persons who lead a healthy lifestyle, and are free from genetic abnormalities or diseases affecting their fertility.
How Many Donor-Egg Cycles Before Success?
One of the most common frequently asked questions when it comes to getting started with donor-egg IVF is how many cycles are necessary before achieving pregnancy.
Thanks to the high success rates reached with these treatments, statistics show that a large number of patients are able to become pregnant on the first try. Should a successful pregnancy not be achieved on the first try, it is estimate that the success rates after the third attempt reached 90% in most cases.
However, one should keep in mind that determining the precise number of attempts that each patient will need is difficult, as it varies on a case-by-case basis, and at the same time is dependent on various factors.
Reasons Donor-Egg IVF Fails
The success rates of IVF treatments with donor eggs are generally high. However, the ultimate goal may not always be achieved, either because the embryos are unable to implant, or due to a miscarriage. This may happen as a consequence of:
Uterine abnormalities
Polyps, endometriosis, an intrauterine adhesion or septum, among others. As they may prevent or hinder implantation, surgery may be required before getting started with the treatment.
Immune disorders
The immune system should be working properly for implantation and a successful pregnancy to occur, as the mother's body should be capable of "accepting" the embryo.
Blood clotting disorders (hypercoagulability)
Clotting properly is essential for the chances for embryo implantation to rise, and therefore for a term pregnancy to take place.
Genetic disorders
The sperms may carry a genetic abnormality that prevents the embryo from developing.
Poor embryo quality
Low-quality spermatozoa may lead to poor-embryo quality. Also, it is possible, though unusual, for donor-egg quality to be low, in which case choosing another donor would be advisable.
