Fertility Scan (Cont.)
Baseline scan
At your first scan we will also perform a baseline check to determine the position and shape of your womb and to determine if there are fibroids or polyp’s present that could cause complications with an embryo implanting in the womb. We will also check the presence of ovarian cysts.
How and when does ovulation occur?
The ovaries
The egg develops within a follicle in the ovary. This follicle is a thin-walled structure containing fluid with the egg attached to the wall. .The follicle appears as a circular fluid-filled bubble on the screen, (see image) and can be seen when it is about 7 to 8 mm in size. It grows at about 1 to 2 mm per day, and is ready for ovulation when it measures 17 to 25 millimeters in diameter average 18mm to 22mm
Following ovulation, the follicle usually disappears from the scan picture completely or the walls of the follicle become irregular and collapsed (corpus luteal cyst) and this is the best evidence that ovulation has occurred.
Often, at the same time, fluid can also be detected in the abdomen behind the uterus. This is the follicular fluid that is released when the follicle ruptures.
The lining of the womb (endometrium)
The lining of the womb must also be receptive to the fertilized egg in order for the pregnancy to implant itself in the womb. As well as measuring the follicles we will also be checking the appearance and thickness of the lining as the cycle progresses.
