Answer:
Corpus luteum
Explanation:
Corpus luteum is the temporary endocrine tissue that is formed after ovulation. The release of a secondary oocyte from the Graafian follicle is followed by the transformation of ruptured follicle into corpus luteum. Corpus luteum is maintained by luteinizing hormone (LH). If the secondary oocyte is fertilized, the corpus luteum is maintained as it secretes estrogen and progesterone.
Estrogen and progesterone are the female sex hormones required to maintain pregnancy. The estrogen and progesterone prepare the uterus for implantation and inhibit the secretion of GnRH, FSH, and LH to prevent menstruation. If fertilization does not occur, corpus luteum is degenerated after 8 days due to a reduction in LH levels.
