Corpus luteum graviditatis

英语百科

Corpus luteum

Steroidogenesis, with progesterone in yellow field at upper center. The androgens are shown in blue field, and aromatase at lower center - the enzyme present in granulosa lutein cells that convert androgens into estrogens (shown in pink triangle).
Vaginal ultrasound showing a corpus luteum in a pregnant woman, with a fluid-filled cavity in its center.

The corpus luteum (Latin for "yellow body"; plural corpora lutea) is a temporary endocrine structure in female ovaries that is involved in the production of relatively high levels of progesterone and moderate levels of estradiol and inhibin A. It is colored as a result of concentrating carotenoids (including lutein) from the diet and secretes a moderate amount of estrogen to inhibit further release of gonadotropin-releasing hormone (GnRH) and thus secretion of luteinising hormone (LH) and follicle-stimulating hormone (FSH). A new corpus luteum develops with each menstrual cycle.
