It is unlikely that IVF will be successful at the age of 50. When a woman is around 50 years old, her ovarian function has declined, and some women have entered perimenopause or have already gone through menopause, and the number and quality of eggs have declined significantly. Firstly, it is difficult to retrieve eggs, and even if the retrieval is successful, the quality of fertilized eggs is poor. Secondly, due to the relatively low level of estrogen in the body, estrogen and progesterone can promote the proliferation and secretion of the endometrium, and the low level of these two hormones will easily lead to a thin endometrium, which is also not conducive to the fertilization of the egg. In addition, women 50 years old, the whole body system function decline, even if the embryo transfer success, the embryo in the subsequent growth and development process, pregnant women are prone to pregnancy complications, such as gestational diabetes, hypertension and other complications; the fetus embryonic development, developmental deformities that can easily lead to preterm delivery, stillbirth occurs the chance of higher. Women 50 years old to maintain a good mood, pay attention to the regularity of life, this age to do IVF, is to be carried out under the assessment of the doctor.
