👉 The BBS fluid, or Basal Body Fluid, is a clear, colorless, and slightly viscous liquid produced by the ovaries in females, playing a crucial role in the menstrual cycle and fertility. It serves as a medium for transporting hormones like estrogen and progesterone between the ovaries and the uterus, ensuring proper ovulation and endometrial preparation for potential pregnancy. The fluid's composition changes throughout the menstrual cycle, becoming more abundant and nutrient-rich during the follicular phase to support the growing ovarian follicle and eventually transforming into a thicker, more gel-like substance during the luteal phase to prepare the uterine lining. This dynamic nature of BBS fluid is essential for regulating reproductive processes and maintaining female fertility.
