Follic scan when on clomid treatment in case of infertility
Follicle Tracking | Follicle Scanning
If you are a woman trying to conceive, one of your biggest challenges in fertility as you grow older is the suitability of your eggs. Egg production can be greatly affected by your age both in quality and in number. By the time you are in your late 30s or early 40s, you will probably have more poor quality eggs available than good quality eggs. The impact of poor quality eggs is reflected in the general decline of pregnancy rates as women age.
One of the first steps a woman should take when making the decision to conceive is to have Follicle (Follicular) Tracking carried out by a doctor or a qualified sonographer. This will help to identify two things; whether or not she is ovulating and, if she is, the scan will additionally pinpoint the exact time when the follicle ruptures and releases the egg. This information enables a couple to time intercourse in order to maximise their chances of conception.
What is Follicle Tracking?
Follicle Tracking involves a series of vaginal ultrasound scans, starting from day 9 to day 20 of your cycle. These scans allow you to observe the follicle(s) developing in your ovary. The scans are performed using a small plastic probe which is inserted in the vagina. The process is relatively painless.
The Process of Follicle Tracking
Initially, a base line scan is carried out to determine the overall health of the reproductive area and to check for any issues that may impede conception such as fibroids, polycystic ovarian syndrome or ovarian cysts.
During a normal cycle the egg develops within a follicle in the ovary. This follicle is a thin walled structure containing fluid along with the egg attached to its inner membrane. The follicle appears as a circular fluid-filled bubble on the screen and can be seen when it is about 7-8 mm in size. It grows at a rate of about 1-2 mm per day and is ready for ovulation when it measures within the correct range of 17-25 mm in diameter. During the tracking process, the number of developing follicles and their size are measured and charted as well as ovulation being noted if and when it occurs.
In conjunction with assessment of the follicles, the development of the lining of the womb is also recorded during Follicle Tracking. In order for a pregnancy to occur, the uterine lining must be receptive to a fertilised egg in order for the embryo to implant successfully. The Follicle Tracking process measures the appearance, development and thickness of the lining of the womb as the cycle progresses.
How do I know Ovulation has occurred?
Following ovulation, the follicle usually disappears from the scan picture completely or the walls of the follicle become irregular and collapsed. This is the best evidence that ovulation has occurred. Fluid can often be simultaneously detected in the abdomen behind the uterus. This is the follicular fluid that is released when the follicle ruptures.
What else can Follicle Tracking detect?
As well as general issues that may impede pregnancy, which will be identified during the base line scan, there are other problems that Follicle Tracking can detect, including:
