Solution
The correct option is D Corpus luteum
A corpus luteum is a yellowish mass of follicular cells that functions like an endocrine structure. LH hormone causes the cells of the ruptured follicle to form corpus luteum. LH hormone also stimulates corpus luteum to secrete estrogen and progesterone. Corpus luteum secretes large amounts of progesterone which is essential for preparing inner wall of the uterus for implantation. Progesterone maintains endometrium which is thickened by estrogen. In luteal phase, the endometrium further thickens due to estrogen hormone also secreted by corpus luteum. Maintenance of endometrium by progesterone is necessary for implantation of the fertilized ovum and maintenance of pregnancy.
