Turner syndrome is one of the most common chromosomal abnormalities in humans, and represents an important cause of early menopause. It is caused by the total or partial loss of one of the X chromosomes (women usually have 2 X chromosomes).
The vast majority of women with Turner syndrome will be sterile due to ovarian failure. However, there is a small percentage of women (about 5%) who will be able to achieve natural gestations. It will be more likely if you have had spontaneous menstruations or if you have a mosaic Turner syndrome (when some cells have one X chromosome and two other X chromosomes).
Some adolescent women or Turner mosaics will have enough ovarian function to respond to ovarian stimulation and may vitrify oocytes to become mothers later or perform in vitro fertilization. However, the vast majority of women with this chromosomal alteration will have to resort to ovodonation.
In addition, for these women there is an increased risk of aortic dissection during pregnancy and postpartum, which will require a complete medical evaluation before seeking gestation, paying special attention to cardiovascular and renal function.
