follikulaarimäärä

Follikulaarimäärä, commonly referred to as the antral follicle count (AFC), is a diagnostic measure used in reproductive medicine to assess ovarian reserve. It indicates the number of small, fluid-filled follicles in the ovaries that are typically between 2 and 10 millimeters in diameter, observable through transvaginal ultrasound. This count provides an estimate of a woman’s remaining egg supply and overall ovarian function.

Follikulaarimäärä is considered a valuable tool for predicting ovarian response during assisted reproductive treatments such as in vitro fertilization (IVF). A higher follicle count usually correlates with a greater likelihood of successful ovarian stimulation and fertilization, whereas a lower count may suggest diminished ovarian reserve and reduced fertility prospects. The measurement is often combined with other markers, such as hormone levels of follicle-stimulating hormone (FSH) and anti-Müllerian hormone (AMH), to provide a comprehensive assessment of ovarian health.

The count typically varies with age and individual health factors. Women in their reproductive years generally have a higher follicular count compared to perimenopausal women. The assessment of follikulaarimäärä is non-invasive, quick, and safe, making it a routine part of fertility evaluations. However, it is important to interpret the results in the context of individual health and lifestyle factors, as the AFC provides an estimate rather than an exact count of remaining eggs.

While follikulaarimäärä is useful in fertility prognosis, it does not determine individual fertility outcomes alone. Other factors, including the quality of the eggs and the presence of fertility-related issues, also play crucial roles. Despite its limitations, AFC remains a standard and informative parameter in reproductive healthcare, aiding clinicians and patients in understanding ovarian function.
