Assistance is provided in monitoring the follicular growth, ovulation and timing of the intercourse. There is no stimulation of ovaries with any drugs and this is the most natural form of assisted conception.
Normally a woman produces and releases one egg every month. If she has 28 to 30 day cycle, ovulation (the release of an egg from an ovary) occurs between days 12 to 16 of the cycle. In follicular tracking, an ultrasound scan is arranged on day 10 of the cycle (day 1 is the first day of the period). This scan will show the size of the follicle and the thickness and nature of the endometrium.
When the follicle reaches a size of 16 mm in diameter, one will be advised to use an ovulation prediction kit (LH surge kit), which is available from the clinic or any chemist. At the same time further scans will be arranged until the follicle reaches grows to 18 mm in diameter. When the ovulation prediction kit is positive (by showing 2 lines, it indicates the occurrence of LH surge to stimulate ovulation. The couple are then advised to have intercourse for the next three days starting from that day.
