Final answer:
The typical size of a corpus luteum cyst ranges from 1.5 to 3 centimeters, although some may grow larger. The corpus luteum is a hormone-secreting structure formed from the ruptured follicle after ovulation during the luteal phase of the ovarian cycle.
Step-by-step explanation:
The typical size range of a corpus luteum cyst varies, but most are between 1.5 to 3 centimeters in diameter. Occasionally, they can become larger, potentially reaching sizes of up to 5 centimeters or more. The corpus luteum itself originates from the ruptured follicle after an egg, or secondary oocyte, has been released during the process known as ovulation. During the luteal phase of the ovarian cycle, the corpus luteum secretes crucial hormones, primarily progesterone and some estrogen, to support the potential implantation and development of a fertilized egg. If fertilization does not occur, the corpus luteum will degenerate and be replaced by a corpus albicans.
