What role do follicle-stimulating hormone (FSH) and luteinizing hormone (LH) play in the menstrual cycle?
Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are two key hormones that regulate the menstrual cycle. FSH helps stimulate the growth of ovarian follicles, which contain eggs, while LH triggers ovulation, the release of the egg from the follicle. These hormones work together to regulate the menstrual cycle and prepare the body for potential pregnancy.
What else can I help you with?
What hormone causes ovulation to occur in the menstrual cycle?
The hormone that causes ovulation to occur in the menstrual cycle is called luteinizing hormone (LH).
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).
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.
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.
What hormone causes ovulation to occur in the menstrual cycle?
The hormone that causes ovulation to occur in the menstrual cycle is called luteinizing hormone (LH).

Hormones involved in the menstrual cycle?
Estrogen and progesterone.as wel as follicle-stimulating hormone called FSH and luteinizing hormone or LH, made by the pituitary gland.
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.
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.
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.
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 triggers the menstrual cycle?
luteinizing hormone
When there is a surge of LH during the menstrual cycle what event occurs?
The ovulation takes place due to surge of luteinizing hormone. This hormone comes from the anterior lobe of the pituitary gland.
What stimulates luteinizing hormone?
Luteinizing hormone (LH) is primarily stimulated by the release of gonadotropin-releasing hormone (GnRH) from the hypothalamus. GnRH prompts the anterior pituitary gland to secrete LH, which plays a crucial role in regulating the menstrual cycle and ovulation in females, as well as testosterone production in males. Additionally, estrogen levels can provide positive feedback to enhance LH secretion during the menstrual cycle.
