What else can I help you with?
Can you not have a lh surge but have an estrogen surge?
Yes.
What day does the LH reach its peak concentration?
The luteinizing hormone (LH) reaches its peak concentration around the middle of the menstrual cycle, approximately 24-48 hours before ovulation. This surge in LH triggers the release of the mature egg from the ovary.
What day does LH reach its peak concentration?
Day 14
Lh surge indicates pregnancy?
A Lh surge (known as the luteal surge) indicates ovulation, not pregnancy. The luteal surge causes the follicle to burst which releases the egg into the body cavity, it is then drawn into the fallopian tubule where fertilization occurs. An increase in HCG indicates pregnancy, HCG in blood and urine is the first outward sign of pregnancy.
The surge in LH secretion from the anterior pituitary that causes ovulation can be partially explained by the?
positive feedback of estradiol that increases the release of LH
When does the ova mature?
Human oocytes mature immediately after the surge of LH which occurs at ovulation. The surge of LH causes maturation of the oocyte which is the completion of the first division of meiosis.
Is LH produced in contraceptive pills?
The morning after pill disrupts the LH surge. That's part of how it works. The morning after pill does not contain LH.
What is the relationship between estrogen levels and the LH surge in the menstrual cycle?
Estrogen levels rise during the first half of the menstrual cycle, leading to the LH surge. This surge triggers ovulation, the release of an egg from the ovary.
Ovulation occurs due to a surge in?
LH - leuteinizing hormone
What is the mid cycle events stimulates by a surge of LH?
ovulat
What causes the peak in luteinizing hormone?
In the beginning of the menstrual cycle, LH and FSH stimulate the ovaries to make estrogen. During this time, there is a negative feedback loop, so levels of all three hormones are rather low. Eventually, as the estrogen levels slowly creep up, there comes a time when it switches from negative feedback to positive feedback (not exactly sure what the biochemical basis of this is), and LH and FSH levels skyrocket (estrogen levels go up to, but not as sharply, and there is always more LH than FSH). The LH surge causes ovulaton. The corpus luteum starts secreting progesterone, which inhibits LH and FSH secretion in a negative feedback manner, and so FSH and LH levels drop sharply.
What signal later causes a rapid rise in the levels of FSH and LH?
The rapid rise in the levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) is primarily triggered by a surge in gonadotropin-releasing hormone (GnRH) from the hypothalamus. This surge occurs during the menstrual cycle, particularly just before ovulation, leading to increased secretion of FSH and LH from the anterior pituitary gland. This spike in FSH and LH is crucial for the maturation of ovarian follicles and the triggering of ovulation.
