The presence of ovulation does not prove that the fallopian tubes are open, because ovulation is an ovarian function, while the function of the fallopian tubes is to transport eggs and fertilized eggs. After ovulation, the umbilical part of the fallopian tube picks up eggs and delivers them to the abdomen of the fallopian tube, where they are combined with sperm to form a fertilized egg, which is then sent to the uterine cavity before pregnancy is considered successful. Adhesions or blockage of the fallopian tubes are the main factors leading to non-pregnancy. Therefore, if you have ovulation but have not been able to conceive, consider that it is due to tubal incompetence and you need to check to see the condition of the tubes. In addition, in patients with ovulatory dysfunction, polycystic ovary syndrome or hyperprolactinemia, for example, the fallopian tubes are mostly normal. To check whether ovulation is occurring, blood tests for hormones and ultrasound are needed, while to determine whether the fallopian tubes are functioning normally, fluid or imaging is needed to determine whether they are normal, which are two completely different factors of infertility.
