What is the Meaning of FSH Signaling?

FSH Signaling describes the complex molecular cascade initiated when Follicle-Stimulating Hormone (FSH), secreted by the anterior pituitary, binds to its specific G-protein coupled receptor (FSHR) located on target cells, predominantly in the gonads. This binding event transduces an extracellular signal into intracellular events crucial for gamete maturation and sex steroid production. Appropriate signaling fidelity is paramount for reproductive endocrinology.

What is the Origin of FSH Signaling?

The term originates in reproductive endocrinology, where FSH was identified as a key gonadotropin regulating ovarian and testicular function. "Signaling" refers to the mechanism by which the hormone communicates its instruction across the cell membrane to elicit a functional response.

What is the Mechanism of FSH Signaling?

Upon binding to FSHR, the associated G-protein activates adenylyl cyclase, leading to a rapid increase in intracellular cyclic AMP (cAMP) concentration. This secondary messenger then activates Protein Kinase A (PKA), which phosphorylates various downstream targets, including transcription factors that regulate gene expression for steroidogenesis and follicular development. Disruptions in this cAMP-dependent pathway can severely impair ovarian reserve and function.
