Ovulation Detection

When does ovulation occur?

Once a follicle matures, containing a microscopic egg, the hypothalamus signals the pituitary to release a burst of leutinizing hormone (LH) which stimulates ovulation to occur within 36 hours.

How can I detect ovulation?

Ovulation can be documented using a basal body temperature (BBT) chart, or by monitoring the level of LH with a urinary test kit. Changes in your cervical mucous may also signal the ovulatory period. It is important to predict the approximate time of ovulation in order to ensure that intercourse occurs on the most fertile days.

How does a urinary LH predictor kit work? 

LH is excreted in the urine; therefore, increased levels in the bloodstream are measurable by urinary test kits. These kits predict ovulation 1-2 days in advance so they are much better for timing intercourse.

How does a BBT chart work?

A thermometer may measure a slight rise in temperature (.5 degrees) that occurs shortly after ovulation. The increase in body temperature is associated with the production of progesterone and indicative of ovulation. We rarely recommend BBT charting because it is time consuming, inconvenient, and less accurate than urinary LH measurements.
