Normal Antral Follicle Count

The normal antral follicle count (AFC) is an important indicator of a woman’s ovarian reserve and can provide valuable insights into her fertility potential. During a woman’s menstrual cycle, multiple antral follicles develop in the ovaries. These small follicles contain the immature eggs that have the potential to be released and fertilized.

**So, what exactly is the normal antral follicle count?**

The normal antral follicle count refers to the number of small follicles that are visible on an ultrasound examination on the second or third day of a woman’s menstrual cycle. This count provides an estimate of the number of potential eggs that a woman has remaining in her ovaries.

It is important to note that the normal number of antral follicles can vary from woman to woman and can also change as a woman ages. Antral follicle count is just one of the many factors that fertility specialists consider when assessing a woman’s reproductive potential.

Factors that Influence Antral Follicle Count

Several factors can influence a woman’s antral follicle count. Here are some of the key factors to consider:

Age:

Age is the most significant factor that affects the antral follicle count. As a woman ages, her ovarian reserve naturally declines, and the number of antral follicles decreases. This decline in antral follicle count is a normal part of the aging process and is often accompanied by a decline in fertility.

Polycystic Ovary Syndrome (PCOS):

PCOS is a common hormonal disorder that can impact a woman’s fertility. Women with PCOS often have a higher number of small follicles in their ovaries, leading to an increased antral follicle count. While a high antral follicle count may sound positive, it is important to note that PCOS can also lead to irregular ovulation or anovulation (lack of ovulation), which can make it more difficult for women with PCOS to conceive.

Other Factors:

Certain medical conditions and lifestyle factors can also influence antral follicle count. These may include smoking, chemotherapy or radiation therapy, ovarian surgery, or autoimmune diseases.
