Ovulation period is not pregnant in the same room, is it blocked fallopian tube?

If the menstrual cycle is regular, ovulation period is not pregnant for a long time, not necessarily fallopian tube blockage, but also may be caused by incomplete follicular development, poor male sperm quality, etc. You can go to the hospital for tubal catheterization, B-ultrasound, laparoscopy and other examinations to determine whether there is fallopian tube blockage.
