Abstract:
Follicle-stimulating hormone (FSH) and its receptor (FSHR) constitute one of the core signaling axes that regulate the reproductive process of mammals. Studies have shown that the glycosylation pattern of FSH and the polymorphism of receptor genes can affect the ligand-receptor binding efficiency and downstream signal intensity, and are related to the susceptibility and phenotype of diseases such as polycystic ovary syndrome and primary ovarian insufficiency. FSH/FSHR not only regulates normal reproductive function by activating multiple pathways such as cyclic adenosine monophosphate/protein kinase A, PI3K/Akt, β-arrestin, and MEK/ERK, but also promotes the progression of malignant tumors such as ovarian cancer and prostate cancer through mechanisms like activation of cancer stem cells, metabolic reprogramming, and angiogenesis. Therefore, targeting the FSH/FSHR axis has become a highly promising therapeutic strategy. This review summarizes the latest research advances of FSH/FSHR axis in reproductive system diseases and tumors, especially the therapeutic value of FSH/FSHR signaling axis.

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...

Abnormal Proliferation
Hormonal Control of the Ovarian Cycle
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...

Gonadal and Placental Hormones
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...
