FOLLICULAR SCAN
FOLLICULAR SCAN
A follicular scan, also known as follicle tracking or ovulation monitoring, is a type of ultrasound examination used in fertility assessment and management. It involves the monitoring and measurement of ovarian follicles, which are fluid-filled sacs within the ovaries that contain developing eggs (oocytes).
During a follicular scan:
- Monitoring of Follicle Development : The ultrasound technician or sonographer tracks the growth and development of ovarian follicles throughout the menstrual cycle, typically starting from the early follicular phase (days 2-5) and continuing until ovulation occurs.
- Measurement of Follicle Size : The technician measures the size of the dominant follicle(s) in each ovary, typically focusing on the leading follicle that is likely to release an egg during ovulation. The size of the follicle helps predict the timing of ovulation.
- Endometrial Thickness : The thickness of the endometrial lining (uterine lining) is also assessed during the scan. A thickened endometrium is favorable for embryo implantation.
- Hormone Monitoring : In some cases, blood tests may be performed alongside follicular scans to measure hormone levels, such as estradiol and luteinizing hormone (LH), which help further assess ovarian function and predict ovulation.
Follicular scans are commonly used in assisted reproductive techniques (ART) such as intrauterine insemination (IUI) and in-vitro fertilization (IVF) to optimize the timing of ovulation and insemination procedures. They can also help diagnose conditions such as polycystic ovary syndrome (PCOS) and monitor response to fertility medications.
Overall, follicular scans play a crucial role in fertility evaluation and treatment by providing valuable information about ovarian function and follicle development, helping couples achieve their reproductive goals.
