まとめ
ホルモン療法を受けていない閉経後の女性では,卵泡刺激ホルモン (FSH) とルテイン化ホルモン (LH) 濃度が著しく変化します. これらのゴナドトロピンのパターンは,老化に関連した健康結果に影響を与える可能性があります.
科学分野:
- 内分泌学
- 生殖 健康
- ゲロントロジー
背景:
- 卵泡を刺激するホルモン (FSH) やルテイン化ホルモン (LH) を含むゴナドトロピンは,老化プロセスに関与しています.
- 過去の研究では,更年期後の女性のFSHとLHの長期パターンを十分に特徴づけることができませんでした.
研究 の 目的:
- ホルモン療法を使用していない閉経後の女性のFSHとLHレベルの時間経過の異なる軌道を特徴づける.
- これらのホルモンパターンと人口統計的または臨床的要因の間の潜在的な関連性を特定する.
主な方法:
- 女性の健康イニシアチブのOsteoPerio研究から291人の閉経後の女性のFSHとLHのレベルを20年間にわたって分析するために,グループベースの経路モデリングが使用されました.
- 参加者はデータ収集時にホルモン療法を使用していなかった.
主要な成果:
- 安定した低値,増加,そして増加に続く初期減少のパターンを特定した.
- 3つの異なるLH経路が特定されました. 減少,最初は減少,それから増加,そして最初は減少,それから急激に増加.
- 高いFSHとLHの経路は,決して喫煙者ではなく,脂肪が低く,より重度の熱帯と関連していました.
結論:
- ホルモン療法を受けていない女性では,更年期後のFSHとLHの値に顕著な変動がある.
- これらの異なった閉経後のゴナドトロピンのパターンと老化に関連する健康上の結果との関係を調べるためにさらなる研究が必要である.

Menopause
248
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Hormonal Control of the Ovarian Cycle
2.7K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Hormonal Regulation of the Menstrual Cycle
688
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Gonadal and Placental Hormones
1.7K
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...

Ovarian Cycle
1.8K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Oogenesis
64.3K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
