Patient's question:
I had some mild lower abdominal pain a few weeks ago. I went to the hospital for a thorough examination of the secretions and had an ultrasound. The doctor suspected it was a corpus luteum cyst and said I should follow up after my next menstrual period. I want to ask what a corpus luteum cyst is?Doctor's answer:
Postmenopausal ovular fluid flows out, intrafollicular pressure rises, the follicular wall collapses, forming many folds. The granulosa cells and theca cells of the follicular wall infiltrate inward, surrounded by the connective tissue of the follicular outer membrane, collectively forming the corpus luteum. The corpus luteum is a cystic structure. From 7 to 8 days postmenopause, its volume and function exceed the peak, with a diameter of 1 to 2 centimeters and a yellow appearance. If the ovum is not fertilized postmenopause, the corpus luteum begins to atrophy from 9 to 10 days postmenopause, gradually transforming into a corpus albicans. If the corpus luteum persists or enlarges, it forms a corpus luteum cyst.
