背景情况:
- 循环中的抗穆勒尔激素 (AMH) 水平对于评估卵巢储备至关重要.
- 肠道微生物群对包括生殖激素在内的全身健康的影响是一个新兴的研究领域.
- 了解肠道细菌和AMH之间的潜在因果关系可以为生殖健康提供新的见解.
研究的目的:
- 调查肠道微生物组成和循环AMH水平之间的潜在因果关系.
- 用遗传方法识别可能影响AMH度的特定肠道细菌种群.
主要方法:
- 采用两样本的门德尔随机化 (MR) 方法,利用全基因组关联研究 (GWAS) 总结统计数据.
- 分析了来自MiBioGen联盟 (14,306个人) 的肠道微生物群数据和来自7049名绝经前妇女的AMH数据.
- 利用多种MR方法 (IVW,MR-Egger,加权中位数,加权模式) 来评估关联并进行灵敏度分析.
主要成果:
- 对MR的分析表明,特定细菌群和AMH水平之间存在潜在的关联.

Anatomy of the Intestines
74.1K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Hormonal Regulation of the Menstrual Cycle
704
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...

Oogenesis
64.4K
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...

Gonadal and Placental Hormones
1.8K
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...
