Luteinizing hormone

Japanese: luteinizing hormone（英語表記）luteinizinghormone

...The sexual cycle is brought about by a kind of biological autoregulatory mechanism between the nervous system and the endocrine system in the diencephalon-pituitary-ovarian axis, and is brought about by the interaction between the hypothalamus and anterior pituitary gland in the brain and the ovaries, which in turn regulate the secretion of hormones from each.
[Menstrual Cycle]
Under the control of the diencephalon and hypothalamus, the anterior pituitary gland secretes two types of gonadotropins (gonads) into the bloodstream in a regular cycle according to the menstrual cycle: follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Follicle-stimulating hormone stimulates the ovarian follicles to mature.

From [Gonadotropin]

…They are also called gonadotropic hormones. In vertebrates, they include two hormones secreted from the anterior pituitary gland: follicle-stimulating hormone (abbreviated as FSH) and luteinizing hormone (abbreviated as LH) or interstitial cell-stimulating hormone (abbreviated as ICSH), and chorionic gonadotropin (abbreviated as CG, but abbreviated as hCG in humans), secreted from the placenta. Both are glycoproteins, and in humans, FSH has a molecular weight of about 35,000, while LH and hCG have a molecular weight of about 30,000. …

From the Pituitary Gland

…(5) Follicle-stimulating hormone (FSH) In women, it acts on the ovaries to promote the development of primordial follicles, and in men, it promotes spermatogenesis in the testes. (6) Luteinizing hormone (LH) In women, it promotes the development of follicles together with FSH, and stimulates the production and secretion of estrogen. At the mid-menstrual period, a rapid secretion of LH occurs from the anterior lobe, and in response to this, the mature follicles in the ovaries ovulate and form the corpus luteum. …

…性周期は，間脳･脳下垂体‐卵巣系における神経系と内分泌系との間の，一種の生体自動調節機構によってもたらされるもので，脳の視床下部･脳下垂体前葉と卵巣とが相互に作用しあい，それぞれからのホルモン分泌が巧妙に調節されて起こる。
［月経周期］
　間脳･視床下部の支配のもとに，脳下垂体前葉から，月経周期に応じて，2種類の性腺(または生殖腺)刺激ホルモン(ゴナドトロピン)，すなわち卵胞(または濾胞)刺激ホルモンfollicle‐stimulating hormone(FSHと略記)と黄体形成ホルモンluteinizing hormone(LHと略記)が規則正しく周期的に血中に分泌される。卵胞刺激ホルモンは卵胞を刺激して卵胞を成熟させる。…

…(5)卵胞刺激ホルモンfollicle‐stimulating hormone(FSH)　女性では卵巣に働いて原始卵胞の発育を促す作用をもち，男性では睾丸の精子形成を促進する。(6)黄体形成ホルモンluteinizing hormone(LH)　女性ではFSHとともに卵胞の発育を促進し，エストロゲンの産生と分泌を刺激する。月経中間期には，前葉から急激なLHの分泌が起こり，卵巣の成熟した卵胞はこれに反応して排卵を起こして黄体が形成される。…
