Why can the corpus luteum degenerate when the placenta is fully formed?
The corpus luteum degenerates when the placenta is fully formed because the placenta takes over the production of hormones, particularly progesterone, that are necessary to maintain the pregnancy. Initially, the corpus luteum produces these hormones to support the early stages of pregnancy, but once the placenta is established and functional, it secretes sufficient hormones to sustain the pregnancy independently. This transition reduces the need for the corpus luteum, leading to its degeneration.
