The prerequisite for pregnancy is the union of the sperm with the egg, therefore pregnancy cannot occur without ovulation.
Strict preconditions are required for a successful pregnancy, including the formation of a fertilized egg, the disappearance of the zona pellucida in the blastocyst, the synchronized development of the endometrium and the presence of sufficient estrogen and progesterone in the body. Among these is the formation of a fertilized egg, which is the union of an egg with a sperm, and if there is no mature follicle in the ovary to rupture and ovulation does not occur, pregnancy will not occur.
Diseases that can lead to non-ovulation may be premature ovarian failure, polycystic ovary syndrome, hyperprolactinemia, etc., which can lead to infertility in patients.
If the patient is in the stage of preparation for pregnancy, it is recommended to consult the hospital in time, complete the relevant examinations, clarify the cause of the disease, and target treatment and therapy under the guidance of the doctor.
