概括

患有多囊性卵巢综合征 (PCOS) 的青少年女孩呈现出不同的表型. 瘦身的女孩表现出神经内分泌驱动的高雄性质,而肥胖的女孩表现出胰岛素抵抗驱动的PCOS.

科学领域:

生殖内分泌学生殖内分泌学
儿科内分泌学儿科内分泌学
代谢障碍代谢障碍代谢障碍

背景情况:

多囊性卵巢综合征 (PCOS) 是一种影响女性的复杂内分泌疾病.
在成年PCOS患者中识别出不同的代谢和生殖亚组.
青少年PCOS的表型异质性需要进一步研究.

研究的目的:

在被诊断患有PCOS的青少年女孩中调查不同的表型.
为了区分瘦 (LN-G) 和肥胖 (OB-G) 患有PCOS的青少年女孩.
为了比较LN-G和OB-G PCOS表型之间的生殖和代谢概况.

主要方法:

分析了CALICO PCOS数据库中的354名青少年患者的数据.
瘦 (LN-G) 定义为BMI<85百分位;肥胖 (OB-G) 定义为BMI≥95百分位的年龄/性别.
在LN-G和OB-G组之间比较生殖激素和代谢标志物.

主要成果:

在LN-G PCOS中,黄素化激素 (LH),总和氨的含量较高.
OB-G PCOS表现出较低的性激素结合球蛋白 (SHBG) 和较高的自由.
OB-G还呈现出血红蛋白A1c升高,氨酸转移酶,甘油三和黑色糖.

结论:

青少年PCOS在瘦身和肥胖女孩中呈现出不同的表型.
瘦身女孩 (LN-G) 呈现出一种生殖表型,表明神经内分泌驱动的卵巢雄激素过量.
肥胖女孩 (OB-G) 显示出与胰岛素抵抗和降低SHBG相关的表型,导致过高雄性质.

Oogenesis

Oogenesis

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...

Hormonal Control of the Ovarian Cycle

Hormonal Control of the Ovarian Cycle

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...

Ovarian Cycle

Ovarian Cycle

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...

Signs of Puberty

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
