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 anterior pituitary hormone causes the enlarged ovarian follicle to rupture and release a mature ovum?
Luteinizing hormone (LH) is the anterior pituitary hormone that causes the enlarged ovarian follicle to rupture and release a mature ovum during ovulation.
The luteinizing hormone stimulates ovulation in the female?
Yes, but it is the surge that brings on ovulation.The luteinizing hormone is required to stimulate the ovarian follicles in the ovary to produce the female sex hormone, estradiol. And around day 14 of the cycle, a surgein luteinizing hormone levels causes the ovarian follicle to tear and release a mature oocyte (egg) from the ovary, a process called ovulation.For the remainder of the cycle (weeks three to four), the remnants of the ovarian follicle form a corpus luteum. Luteinizing hormone stimulates the corpus luteum to produce progesterone which is required to support the early stages of pregnancy, if fertilization occurs.

Luteinizing Hormone
Which hormone stimulates the production of testosterone?
Hormones are regulated by what are called negative feedback mechanisms. When more is needed, more will be released and the opposite is true when there is enough. For example, the secretion of follicle-stimulating hormone decreases as the amount of circulating estrogen increases.
