"The study group will start urine LH (LHu) testing according to the mean diameter of the leading follicle on ultrasound as per :~13mm or less - Repeat ultrasound scan in 1-2 days 14-17mm - start urine LH testing the evening of the day of the scan 18mm or greater - do one LHu test in the afternoon of the day of the scan before HCG administration Once the patient has commenced LHu testing she will perform 2 tests per day. The tests will be performed at 7am and 7pm. LHu testing will continue until the time of HCG administration or positive uLH.If the LHu result is positive either in the morning or afternoon, the insemination will be the next morning without the administration of exogenous HCG.~If the patient has an inconclusive LHu result, a blood LH test will be taken. If the LH blood test is negative (\<8 IU\\L) she will continue testing LHu. If the LH blood test is positive (≥ 8 IU\\L) the insemination will be the next day."
