What hormone triggers ovulation?

Follicle Stimulating Hormone
Luteinizing Hormone
Oxytocin
Thyrotropin

The correct answer is: Luteinizing Hormone

Luteinizing Hormone is the key hormone responsible for triggering ovulation in both humans and poultry. This hormone is produced and released by the anterior pituitary gland in response to the Gonadotropin-Releasing Hormone (GnRH) from the hypothalamus. In poultry, a surge of luteinizing hormone leads to the maturation and subsequent release of the ovum or egg from the ovary. This physiological process is crucial for reproduction, as the release of the egg allows for fertilization to occur. The presence of luteinizing hormone ensures timing and regulation of ovulation, which is fundamental in poultry production and breeding programs. Understanding the role of this hormone in ovulation helps in managing breeding cycles and improving the fertility rates in poultry.
