Final answer:
The true statement about the corpus luteum is that it becomes the corpus albicans. The corpus luteum, formed from the luteinization of granulosa and theca cells post-ovulation, produces progesterone, which is essential for pregnancy maintenance.
Step-by-step explanation:
The statement concerning the corpus luteum that is true is: (D) It becomes the corpus albicans. The corpus luteum is an endocrine structure in the ovary that forms from the granulosa and theca cells after an oocyte has been ovulated.
It is responsible for producing progesterone, which is critical for the establishment and maintenance of pregnancy. This process is called luteinization, and it is initiated by an LH surge. Progesterone from the corpus luteum inhibits the production of GnRH, FSH, and LH to prevent the development of new dominant follicles during this time.
As the corpus luteum degenerates, if pregnancy does not occur, it forms a scar tissue known as the corpus albicans.a
