With the passage of time, a woman's ovarian reserve diminishes and her reproductive potential also decreases. In addition, especially after the age of 40, the probability of chromosomal alterations in the embryos is greater, which can not only prevent pregnancy, but also prevent it from progressing favorably.
Reproductive medicine offers several alternatives for the cases of older women who seek pregnancy and cannot achieve it with their own eggs: PGT and ovodonation.
Success rates increase considerably with these treatments. In general, the rate of birth by transfer goes from 25.2% using the woman's own eggs and without PGT to 39.7% if PGT is performed and 41.5% when egg donation is used.
