Ovulation is the release of the matured egg into the fallopian tube.  Irregular or absent menstrual cycles may be a sign that the ovaries are not producing or are irregularly developing eggs. This is also called oligomenorrhea. There are many causes of irregular or absent ovulation. The cells in the brain that control reproduction are adjacent to cells that control other hormones in the body, so if you have an abnormality in another hormone such as the one for the Thyroid gland, which regulates metabolism or with the hormone Prolactin, which regulates breast milk production, this can impact the cells that control ovulation.  Correction of these other hormone abnormalities often corrects irregular menstrual cycles and promotes regular ovulation.
