The method by which the doctor monitors the development of this follicle from the start of the menstrual cycle until it is prepared to release an egg is known as follicular monitoring. It is crucial to the evaluation and planning of IVF. It investigates the ovulation procedure and routinely measures the number of ovarian follicles. Doctors will have examined the follicle development in the ovaries by the time the next egg is released. The likelihood of pregnancy is significantly increased if a couple intends to engage in sexual activity during that time.

The purpose of follicular monitoring

A significant component of reproductive therapies is follicular research. They are crucial for determining whether or not the woman’s body is reacting to treatment. The follicle scans are crucial if someone has selected the IVF route for conception. It assesses the situation, counts the eggs generated in a single ovulation, and evaluates the hormones at play. Increasing the dosage of the medicine will enhance the chance of conception if the hormone levels are out of whack.

The precise moment in the cycle when one will ovulate can be determined with the aid of follicular monitoring. Planning sexual activity during that time increases the likelihood of conception.


It also helps with ovulation-related problem diagnosis. Some of these problems might potentially affect your pregnancy.


However, it does not ensure that the sperm would fertilize the egg and that the fertilized egg will be inserted into the uterus. After ovulation, you may have some problems that impede pregnancy. These scans do not additionally take care of them.

When is it necessary to check follicles?

The development of the follicle inside the ovary can be seen by the doctor using a painless procedure called a follicle scan. Sonographers can see how the egg develops inside the follicle by inserting tiny plastic probes into the vagina. The following are some justifications for considering follicular monitoring:


● Let’s assume you are younger than 35 and have been trying for your pregnancy for a long tome. During this initial stage, you can rule out any ovulation-related problems.
● if you are over 35 and haven’t had a successful pregnancy in the previous six months.
● If you have PCOD, you can experience irregular periods and ovulation. Additionally, cycles without ovulation are possible.

● Whether many follicles are created using IUI or IVF, or fertility drugs are used to trigger ovulation.

On days 6 or 7 of your cycle, the sonographer or the doctor will frequently advise getting these scans. However, it is predicated on the notion that you have a 28-day cycle. She will keep reminding you to come in for the scans every two to three days.

How do tracking follicles work?

Follicle tracking involves a series of 5- to 10-minute-long ultrasound scans of the vagina. The follicles start to grow on the 9th day during the cycle. Once ovulation has begun and the follicles have vanished, the scans stop. After that, having sex is advised for couples. As it maximizes the
time for the sperm and egg to meet, it aids in conception.


The doctor assesses the follicles’ size. The endometrium, which makes up the uterus’s wall, is also measured for thickness. The blood flow towards the follicle and endometrium may also be examined by the doctor using a Doppler scan.


An average mature follicle size of 18 to 25 mm for a healthy pregnancy and an endometrial thickness of at least 10 mm is considered normal.

Who needs tracking follicles?

Women who don’t know when they are ovulating, have miscarried, use Clomid, or take FSH are typically advised to do so.


● Women may require follicle tracking if, despite using prediction kits, they cannot determine when they are ovulating.
● These scans can help people who experienced miscarriages in the initial stages of pregnancy understand what went wrong.
● Women who have been using medicines to treat other issues related to conception or promote ovulation.

Success rate

Ovulation tracking is frequently suggested as the first course of treatment for infertile couples by gynaecologists. Patients need to understand that this is not a foolproof cure. The pair may experience significant stress while trying to time sex, and the success rate for a perfect cycle is average. Ovulation tracking is frequently suggested as the first course of treatment for infertile couples by gynaecologists. This appears to be wise counsel. Simply schedule some vaginal ultrasound scans, which can help you determine exactly when you ovulate. You have sex at this time, and because eggs plus sperm equal a baby, you become pregnant right away!
