Introduction
A follicle measuring 22 × 18 mm is considered a high-quality follicle. When a follicle reaches approximately 18–22 mm in size, it is classified as a mature follicle capable of spontaneous ovulation; intercourse during this period can enhance the likelihood of conception. Follicles smaller or larger than this range typically cannot undergo normal ovulation. It is recommended to take good care of yourself during the ovulatory phase: include foods rich in phytoestrogens in your diet, engage in moderate physical activity, and maintain a positive, relaxed mindset.
A follicle measuring 22 × 18 mm is considered a high-quality, mature follicle. Generally, a follicle reaching approximately 18–25 mm in diameter is deemed mature and capable of spontaneous ovulation; intercourse during this period increases the likelihood of conception. Follicles significantly smaller or larger than this range typically fail to ovulate normally. Details are as follows:
Each month, a woman’s ovaries develop multiple follicles—up to several dozen—which is considered normal. However, most of these follicles cease development before reaching maturity; consequently, only one (rarely two) follicles fully mature and ovulate per cycle. Ovulation occurs once per month, usually about two weeks after the end of menstruation. The released oocyte remains viable for approximately 24 hours. A healthy follicle resembles a fluid-filled sac and varies in size. Follicles grow at an average rate of about 2 mm per day; when they reach a diameter of 18–25 mm, they are considered mature and may rupture and release the oocyte at any time.
It is advisable to take special care during the ovulatory phase. Diet-wise, consider increasing intake of foods rich in phytoestrogens—such as soy products. Engage in moderate physical activity to enhance overall health and maintain a positive, relaxed mindset.
