Monitoring

Once you begin clomiphene citrate therapy, it is important to determine if the treatment has successfully induced ovulation. There are a few ways ovulation can be monitored:

Basal body temperature (BBT) charts
Basal body temperature (BBT) charts show an elevation in a woman’s basal temperature. Levels of +0.5 F for several days indicate ovulation has occurred. Keep in mind that the rise in temperature occurs after ovulation and therefore may not be detected until the day after ovulation. Because of this, BBT charts are not the most efficient method for timing intercourse.
Ovulation predictor kits
Ovulation predictor kits detect the mid-cycle surge of luteinizing hormone (LH). They have the added advantage of turning positive prior to the time of ovulation. This allows for effective timing of intercourse. Many doctors recommend that couples have intercourse the day the predictor kit turns positive and again the following day. Blood tests and ultrasounds are also used to predict ovulation in more complex cases where more precise monitoring of the time of ovulation is required.
Progesterone level
A progesterone level checked 5 to 10 days following the presumed date of ovulation might reaffirm that ovulation took place, and that hormonal support during the second half of the cycle is adequate.
