What Does Your Follicular Monitoring Scan Tell You About Fertility?
Introduction
Is trying to conceive more than a bit overwhelming when you are not quite sure what is going on with your body? An understanding of your ovulation cycle is an important first step in achieving your goal. A Follicular Monitoring Scan, or FMS for short, is an excellent ultrasound procedure that monitors follicle development as it occurs during the cycle and gives you an idea of the follicular growth that has taken place as well as ovulation and lining thickness of your uterus.
A gynaecologist may perform follicular monitoring to determine whether a dominant follicle has formed, when the likely time of ovulation is and therefore when the fertile period of your cycle occurs. It helps couples in natural conception, IUI and ovulation induction fertility treatment.
The test is generally recommended for women with irregular cycles, PCOS, delayed ovulation or difficulty in conception as part of fertility testing. Repeated ultrasounds are performed to assess follicular growth and ovulation to decide the next line of management.
Dr. Roshi Satija at God’s Grace IVF & Fertility Center in Malviya Nagar, Delhi, offers fertility assessments and follicular monitoring.
This blog explores the importance of fertility and follicular monitoring scans, explains how the scan is performed and what follicle size means in terms of pregnancy. It will also help you understand the role of follicular monitoring in natural conception and fertility treatments.
What Is a Follicular Monitoring Scan?
The Follicular Monitoring Scan is an ultrasound procedure to assess the progression of ovarian follicles in the menstrual cycle. Inside the ovaries, each follicle can contain one immature egg. Doctors use scans to observe whether the follicles develop properly. Follicle growth, in conjunction with measurements of endometrial thickness, helps doctors estimate when ovulation will occur.
Typically, a scan of the ovaries and uterus via TVS is used.
Follicular monitoring is a multi-step ultrasound process, usually performed by a gynaecologist, that observes follicle growth throughout a patient’s cycle to determine if and when ovulation occurs.
This type of monitoring is useful for women planning pregnancy naturally or undergoing fertility treatments, as well as for helping to diagnose possible ovulation problems.
A Follicular Monitoring Scan provides valuable information about the functioning of a patient’s ovaries and can aid in planning a conception strategy.
What Is a Follicular Monitoring Scan?
The technique of follicular monitoring entails the use of a series of ultrasound scans that are conducted during a woman’s reproductive cycle to track the onset of ovulation. This procedure enables the gynecologist to determine the condition of the ovaries and to know if the matured ovum will eventually appear.
The following process is usually carried out in the course of this procedure:
1. The First Scan (Day 2 or 3)
When the doctor recommends conducting the first ultrasound, he examines the ovarian cysts along with the state of the ovaries and the uterine lining’s condition; however, the time of conducting the scan may differ.
2. The Follicle Growth Tracking
The second scan takes place around Day 8 or 10; however, this depends on the doctor’s prescriptions. At this stage, the doctor defines the follicles and examines their growth.
3. The Follicle Maturity Monitoring
The maturation process of the follicle is accompanied by its increase and at each stage, it depends whether it is mature or not; however, the size of the follicle should be from 18 mm to 24 mm in diameter when it matures.
4. The Ovulation Detection
The next scans help in determining whether the follicle has already ruptured which is indicative of ovulation
5. Planning Pregnancy or Fertility Treatment
Based on the scan findings, the doctor may advise appropriate timing for intercourse, IUI or other fertility treatment steps.
Overall, follicular monitoring for pregnancy provides valuable information about ovulation and helps doctors make informed decisions about fertility care.
What Is the Ideal Follicle Size for Pregnancy?
The size of the follicle is crucial in determining ovulation and fertility. Follicles in the ovaries have to develop until an egg is released as part of the menstrual cycle. Typically, a mature follicle size is required for conception, which is around 18-24 mm, although this may be different in each person due to their hormone levels.
During the monitoring scan, the physician determines the follicle size by scanning it using an ultrasound machine.
Here are the stages of follicle size development:
– 10-14mm. The follicle size is at the development stage.
– 15-17mm. The follicle is nearing maturity.
– 18-24mm. The follicle is considered mature and ready for ovulation.
Importance of the size of the follicle
An adequately growing active follicle signifies that ovulation may take place. The doctor can make estimations on ovulation.
For women who undergo IUI treatment, monitoring the size of the follicle will help to decide the timing of the procedure.
Nevertheless, the size of the follicle alone does not mean pregnancy because the quality of eggs and sperm, as well as the proper functioning of the uterus, and fallopian tubes are equally important.
Monitoring the follicle size could be a life-safe experience as it allows gynecologists to
