What are the methods of detecting ovulation?
There are various methods for detection of ovulation. The following are a few: • Basal body temperature charts are an inexpensive means of ovulation detection but are inaccurate. • Ovulation can now be predicted by at-home kits that measure luteinizing hormone (LH) in the urine. • Midluteal phase (a week before menses) measurement of serum (blood) progesterone concentrations remains the simplest and most accurate method of detecting ovulation. • Serial pelvic ultrasounds (follicle study) are currently the most accurate noninvasive method of ovulation detection. But even ultrasound is not the perfect test due to the variable ultrasonic appearance of the ovary after ovulation and documentation of retained oocytes in follicles that have collapsed on ultrasound.
