What hormone stimulates ovulation for the most mature ovum?

Estrogen
Progesterone
Luteinizing Hormone
Follicle-Stimulating Hormone

The correct answer is: Luteinizing Hormone

The hormone that stimulates ovulation for the most mature ovum is Luteinizing Hormone (LH). During the ovulation cycle, a surge in LH is critical as it triggers the final maturation of the ovarian follicle that houses the ovum. This surge causes the follicle to release the ovum into the oviduct, a process known as ovulation. Luteinizing Hormone plays a pivotal role in the reproductive system by regulating the menstrual cycle in females and supporting testosterone production in males. Its action is vital as it not only initiates ovulation but also signals the body to subsequently produce hormones that prepare the reproductive tract for potential fertilization. Understanding this mechanism is essential, as it helps to delineate the hormonal interplay that regulates reproduction in poultry and other animals.
