The reasons for not getting pregnant after taking egg-breaking injections may be caused by poor follicle quality, blocked fallopian tubes, poor endometrial environment, and abnormal male semen. 1. Bad follicle quality: if the follicles of a woman are not of good quality, even if she has taken the injection, she will not be able to ovulate normally or the eggs will not be able to be fertilized after ovulation, and she will not get pregnant. 2. Tubal blockage: after the injection, there is mature follicle development, but the woman’s fallopian tube is blocked, the man and the sperm cannot meet to form a fertilized egg, which will also cause the woman to be infertile. 3. Poor endometrial environment: the endometrial environment of the uterus is too thin or there are serious adhesions in the uterine cavity, the poor endometrial environment is not conducive to the fertilization of the egg, which will also lead to the failure of women to get pregnant. 4. Male semen abnormalities: women are all right in every way, but men have abnormal semen, such as sperm deformities and azoospermia, which can also lead to female infertility. Women who have had their eggs broken are not always successful in getting pregnant, and if they have not been able to conceive successfully, they should go to the hospital to check the cause of the problem and treat it.
