Luteinizing hormone (LH) and human chorionic gonadotropin (hCG) serve different roles in reproductive physiology: LH contributes to the driving force behind gonadal steroidogenesis and regulation of ovulation, whereas hCG (in the absence of pathologic abnormalities) is secreted in large amounts only during pregnancy .

2023年5月16日 · Three key hormones that play vital roles in fertility are luteinizing hormone (LH), pregnanediol glucuronide (PdG), and human chorionic gonadotropin (hCG). In this blog, we’ll explore the hormonal relationship between these hormones and their significance in …

2014年3月5日 · Emerging data suggest that these differences between LH and hCG have functional significance. Identifying the unique roles of LH and hCG is key to understanding both normal physiologic processes (e.g., reproduction, placentation) and dysfunctional states (e.g., infertility, gestational and non-gestational neoplasms).

Whereas LH is a key regulator of gonadal steroidogenesis and ovulation, hCG is predominantly active in pregnancy and fetal development. Emerging evidence has revealed endogenous functions not previously ascribed to hCG, including participation in ovulation and fertilization, implantation, placentation and other activities in support of ...

LH and hCG play essential roles in the reproductive cycle. LH plays a key role in follicular maturation and the ovulation process, and hCG is the “pregnancy hormone.” LH and hCG are different in terms of structure, expression, regulation, and function. LH and hCG fundamentally differ in their expression patterns and have complex and unique aspects.

2020年8月6日 · This review summarises the molecular and functional differences between hCG and LH, and provides an overview of the clinical trial data surrounding the use of products for OS that contain LH bioactivity, examining their individual effect on outcomes such as endometrial receptivity, oocyte yield and embryo quality, as well as key pregnancy outcomes.

2017年4月19日 · Our data indicate that rhLH and rhCG differentially promote cell responses mediated by LH/CGR revealing interesting divergences in their potencies, efficacies and kinetics: rhCG was more potent...

2020年1月1日 · Luteinizing hormone (LH) and human chorionic gonadotropin (hCG) originated from an ancestral gene in primates and act on the same receptor expressed in the gonads. In humans, their physiological functions are different and reflect specific molecular features.

2023年8月8日 · LH和HCG的区别通常有含义不同、作用不同、测量方式不同、测量目的不同、参考值不同等。 1、含义不同：LH是指促黄体生成素，是由腺垂体细胞分泌的一种糖蛋白类促性腺激素，而HCG是人绒毛膜促性腺激素，是由胎盘的滋养层细胞分泌的一种糖蛋白。 2、作用不同：LH能够促进胆固醇在性腺细胞内转化为性激素，可以促进卵泡成熟，分泌雌激素、排卵，还有助于黄体的生成和维持，分泌孕激素和雌激素。 而HCG有助于促进胎儿稳定健康地发育。 3、 …

This presentation includes discussion surrounding the role of LH during folliculogenesis, the differences between formulations containing LH, and physiological difference of LH activity provided by either hCG or pure LH on ovarian function.
