Final answer:
The claim is false; the LH surge actually triggers ovulation and leads to the formation of the corpus luteum, which produces progesterone, not the corpus albicans.
Step-by-step explanation:
The claim that the LH surge blocks ovulation and transforms the ruptured follicle into a corpus albicans is False. Instead, the LH surge is responsible for leading to ovulation. It stimulates the resumption of meiosis of the primary oocyte to a secondary oocyte and triggers proteases to break down the structural proteins in the ovary wall, resulting in the expulsion of the oocyte into the peritoneal cavity. Once the oocyte is ovulated, the LH surge promotes the transformation of the remaining follicular tissue into the corpus luteum, not the corpus albicans. The corpus luteum is a yellowish body that begins to produce large amounts of progesterone, crucial for pregnancy establishment and maintenance and which also inhibits further secretion of GnRH, LH, and FSH, thus preventing the development of new dominant follicles during this time.
