What hormone is responsible for triggering ovulation in the menstrual cycle?
The hormone responsible for triggering ovulation in the menstrual cycle is called luteinizing hormone (LH).
How does the LH hormone impact the menstrual cycle?
The LH hormone, or luteinizing hormone, plays a crucial role in the menstrual cycle by triggering ovulation. When LH levels surge, typically around the middle of the cycle, it causes the mature egg to be released from the ovary. This release of the egg is essential for fertility and the continuation of the menstrual cycle.
During which phase of the menstrual cycle does the luteinizing hormone play a crucial role in triggering ovulation?
The luteinizing hormone plays a crucial role in triggering ovulation during the mid-cycle phase of the menstrual cycle.
During the menstrual cycle, how does the hormone LH (luteinizing hormone) impact ovulation and fertility?
During the menstrual cycle, LH (luteinizing hormone) surge triggers ovulation, which is the release of an egg from the ovary. This surge is essential for fertility as it signals the egg to be released and be available for fertilization by sperm.
Which hormone starts the menstrual cycle?
The hormone that starts the menstrual cycle is follicle-stimulating hormone (FSH), which is released by the pituitary gland. FSH stimulates the growth of follicles in the ovaries, leading to the production of estrogen and eventually triggering ovulation.

The luteinizing hormone plays a crucial role in triggering ovulation during the mid-cycle phase of the menstrual cycle.
Which hormone spikes midway through the menstrual cycle and triggers ovulation?
Luteinizing hormone (LH) Luteinizing hormone (LH) secreted by the pituitary gland causes the mature ovarian follicle to rupture, a process called ovulation. -masteringbiology.com

What is the menstrual cycle controlled by?
The menstrual cycle is controlled by hormones, specifically estrogen and progesterone, which are produced by the ovaries. These hormones regulate the different phases of the menstrual cycle, including ovulation and menstruation. Additionally, the hypothalamus and pituitary gland in the brain play a role in controlling hormone production.
The hormone whose surge triggers ovulation is?
The name of the hormone is leuteinizing hormone. It is secreted by the anterior lobe of the pituitary gland. It is released in middle of the menstrual cycle, normally.
Is luteinizing hormone produced only during the luteal phase of the menstrual cycle?
No, luteinizing hormone (LH) is not produced only during the luteal phase of the menstrual cycle. LH is one of the hormones responsible for ovulation, and its surge triggers the release of the egg from the ovary. While LH levels are highest right before ovulation, they are also present during other phases of the menstrual cycle.
The menstrual cycle's hormone levels are shown below. Which hormone is least active while ovulation is occurring?
Progesterone
How does the hormone FSH fluctuate throughout the menstrual cycle and what role does it play in regulating ovulation and the development of ovarian follicles?
During the menstrual cycle, the hormone FSH (follicle-stimulating hormone) fluctuates by increasing at the beginning of the cycle to stimulate the growth and development of ovarian follicles. This hormone is crucial in regulating ovulation by promoting the maturation of the egg within the follicle. As the follicle grows, it produces estrogen, which in turn inhibits FSH production. When estrogen levels peak, it triggers a surge in another hormone called LH (luteinizing hormone), which leads to ovulation. FSH levels then decrease until the next cycle begins.
What is the significance of fsh in the follicular phase of the menstrual cycle?
During the follicular phase of the menstrual cycle, FSH (follicle-stimulating hormone) plays a crucial role in stimulating the growth and development of ovarian follicles, which contain the eggs. This hormone helps to regulate the maturation of the eggs and prepare them for ovulation, which is essential for fertility and the menstrual cycle.
