It then degenerates into a corpus albicans, which is a mass of fibrous scar tissue.

The remains of the corpus albicans may persist as a scar on the surface of the ovary.

Once the corpus luteum regressed the remnant is known as corpus albicans.

The corpus albicans (Latin for "whitening body" ) is the regressed form of the corpus luteum.

It acts on the corpus luteum to cause luteolysis, forming a corpus albicans and stopping the production of progesterone.

After the trauma heals, the subsequent structure is called the corpus luteum (which in turn becomes the corpus albicans before degenerating.)

As the corpus luteum is being broken down by macrophages, fibroblasts lay down type I collagen, forming the corpus albicans.

The corpus albicans is also known as atretic corpus luteum, corpus candicans, or simply as albicans.

However, in placental animals such as humans, the placenta eventually takes over progesterone production and the corpus luteum degrades into a corpus albicans without embryo/fetus loss.

This removes the luteotrophic support provided by the gonadotropin Luteinizing Hormone (LH), and the corpus luteum degrades to a corpus albicans (scar tissue), which is eventually absorbed into the ovary.
