Introduction
Under normal circumstances, a follicle measuring 23×17 mm is considered a dominant follicle, as dominant follicles are typically larger than 10 mm on ultrasound and generally range between 18–23 mm. Ovulation usually occurs within 24 to 48 hours. For individuals with fertility intentions, having intercourse during this period can increase the chances of pregnancy.
Ovarian follicle measuring 23×17 refers to a follicle size of 23×17 mm. This is considered a dominant follicle, and having intercourse within approximately 24–48 hours can increase the chances of pregnancy.
An ovarian follicle is a structure in the ovarian cortex composed of an oocyte surrounded by numerous small follicular cells. Follicles can be classified into three stages—primordial follicle, growing follicle, and mature follicle—based on morphological and functional changes during development. A mature follicle gradually enlarges due to increasing fluid accumulation and bulges toward the surface of the ovary prior to ovulation. A dominant follicle refers to the most advanced follicle among them. In this stage, the primary oocyte increases in size, accompanied by significant synthesis of RNA and proteins. A follicle measuring 23×17 mm qualifies as a dominant follicle, as dominant follicles typically exceed 10 mm in diameter on ultrasound and generally range from 18 to 23 mm. Ovulation usually occurs within 24 to 48 hours. Therefore, for individuals seeking pregnancy, having intercourse during this window can enhance the likelihood of conception.
For overall health, it's advisable to maintain regular sleep patterns, keep the abdomen warm, follow a light diet, and engage in moderate physical activity.
