The Fertility Support Company works with Mr. Rod Irvine, a Consultant Obstetrician and Gynaecologist who has rights at Harley Street, Lister Hospital, The Portland Hospital, London Clinic, and Queen Mary's Sidcup. Mr. Irvine will use Ultrasound and blood hormone testing to track a cycle through; examining follicle growth and endometrial thickness. This gives a lot of information about a woman's fertility, especially in combination with a Basal Temperature Chart. If the endometrium (womb lining) is not thick enough, it is difficult for an egg to implant. The hormone Progesterone has implications in endometrial thickness, as well as in ovulation, and helping the body to ovulate regularly and produce adequate levels of progesterone is something which Traditional Chinese Medicine is very good at achieving.
