A follicle tracking ultrasound looks at the ovaries and uterus internally, using a sterile transducer, paying particular attention to the follicles within the ovaries. This technique gives couples a greater chance of achieving a much wanted pregnancy.

Follicle tracking allows women to know if and when they are ovulating. For a woman to ovulate the egg must be released from a follicle and travel along the fallopian tube. A follicle is a fluid filled sac, situated within the ovary – the follicle acts as a basket to hold and nourish the egg. As the follicle grows the egg matures. When the follicle reaches approximately 19-20 mm ovulation occurs, releasing the egg from the follicle. As the egg travels through the fallopian tube it meets the sperm; once the egg and sperm meet pregnancy is likely to happen.

The ultrasound scanning technique provides information as to when ovulation will occur, thereby informing a couple as to when intercourse should take place.

How follicle tracking works

Follicle tracking is a series of ultrasound scans, which usually takes 10-15 minutes to perform. These scans are performed from day 9 to day 17 of the menstrual cycle. These scans show the development of follicles, assessing their size and growth. Scanning continues until the follicles have disappeared and ovulation has occurred. We can advise couples through this technique when to have intercourse. Follicle tracking is a natural method of assisted conception, as it simply optimises the timing of the sperm and egg meeting.
