Description

This treatment effectively bypasses the fallopian tubes and is the most effective treatment for patients with absent, blocked, or damaged tubes. The woman is given fertility drugs to stimulate her ovaries to produce many follicles Each follicle should contain one egg The chances of pregnancy are increased if more than one egg is obtained and fertilized. The number and size of the developing follicles in the ovaries are measured by ultrasound scans. The ultrasound scans are performed at intervals during the treatment cycle. When the follicles reach the optimal size, preparations will be made for egg collection An oestradiol assay will also be carried out prior to administering HCG, to help determine the timing of egg collection. The final preparation for egg collection involves a hormonal injection given to the woman 36–40 hours pre-operatively. This mimics the natural process that normally triggers ovulation. The eggs are collected vaginally using ultrasound guidance, under general or local anesthesia.
