Hormone receptor dynamics in the human endometrium are crucial for uterine receptivity. Understanding steroid hormone action and metabolism is key for fertility control and treating subfertility.
Area of Science:
- Reproductive Endocrinology
- Molecular Biology
Background:
- Endometrial function is regulated by circulating steroids binding to ligand-activated receptors.
- Steroid hormone action involves cell-specific targets and modulation of local ligand availability by metabolizing enzymes.
Purpose of the Study:
- To provide an overview of hormone receptor dynamics in the human endometrium.
- To highlight the role of progesterone in determining uterine receptivity.
Main Methods:
- Immunohistochemistry to define cell-specific steroid hormone targets.
- Studies involving pharmacological withdrawal of progestogens using progesterone receptor antagonists.
- Microarray analysis of human endometrium, mouse models, and in vitro studies to document gene expression changes.
Main Results:
- Progesterone plays a significant role in regulating gene expression and determining uterine receptivity.
- Steroid metabolizing enzymes modulate local ligand availability within endometrial tissue.
Conclusions:
- Understanding the impact of local and peripheral steroids on endometrial function is vital for fertility control.
- Disturbances in endometrial structure and function related to steroid hormones are implicated in subfertility.

Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
Hormonal Regulation of the Menstrual Cycle
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 release.
