The following tests are used to detect ovulation:
  • Urinary luteinizing hormone (LH) detection: Urinary luteinizing hormone (LH) detection is performed using a kit that comes with multiple detection strips. A woman can test daily around the middle of the month to try to detect an LH surge. This usually occurs the day prior to egg release and therefore might also be used to time intercourse or schedule intrauterine insemination (IUI).
  • Basal body temperature (BBT) charting: Basal body temperature (BBT) charting requires the woman to measure her body temperature before getting up in the morning and record the value to a 1/10th of a degree on a chart.
  • Ultrasounds: Ultrasounds can be used effectively to check for follicle development and determine endometrial thickness. The vaginal probe ultrasounds give the best images and don’t require you to have a full bladder. In ovulation induction cycles, the ultrasound is used to count the number and size of follicles to determine when to release the eggs and to make sure it is safe to do so.
  • Hormone testing and endometrial biopsies: Hormone testing uses progesterone levels to predict ovulation. Progesterone is a hormone produced by the follicle after ovulation and is a sensitive measure of ovulation. It is usually measured around day 21 of a 28-day cycle, near the time of peak secretion from the corpus luteum. Low progesterone levels may require further treatment.
