High-throughput screening of two million compounds in 37 distinct encoded combinatorial libraries using FSH receptor transfected cells provided small molecule agonists such as 1 (EC(50)=3 microM) and 2 (EC(50)=3.9 microM), based on which a focused combinatorial library with a total of 31372 compounds was designed, synthesized, and screened to reveal 72 novel biaryl FSH receptor agonists such as 8a-c as well as a unique combinatorial SAR.

The FSH-FSHR pathway has been considered an essential regulator in reproductive development and fertility. But there has been emerging evidence of FSHR expression in extragonadal organs. This poses new questions and long-term debates regarding the physiological role of the FSH-FSHR, and underscores the need for reliable, in vivo analysis of FSHR expression in animal models.

This article presents a narrative review that explores the potential link between kisspeptin-a key regulator of the hypothalamic-pituitary-gonadal axis-and the pathogenesis of endometriosis. Kisspeptin plays a significant role in regulating reproductive functions by modulating the release of gonadotropin-releasing hormone (GnRH), which in turn stimulates the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Recent studies suggest that kisspeptin may also impact peripheral reproductive tissues and influence inflammatory processes involved in the development of endometriosis.

Ovarian cancer (OC) is the gynecological malignancy with the poorest prognosis. Surgery and chemotherapy are the primary therapies for OC; however, patients often experience recurrence. Given the intimate interaction between OC cells and the tumor microenvironment (TME), it is imperative to devise treatments that target both tumor cells and TME components.

Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are mainly involved in follicle development and ovulation, but FSH receptor (FSHR) and LH receptor (LHR) are also expressed in the immune system. Nevertheless, it is not clear if gestation affects the expression of the FSHR and LHR in the maternal main immune organs (thymus, lymph node, spleen, and liver). In this study, these organs were sampled from the ewes at the estrous cycle, and during early pregnancy, and mRNA and protein expression of FSHR and LHR were analyzed.

Life histories of oviparous species dictate high metabolic investment in the process of gonadal development leading to ovulation. In vertebrates, these two distinct processes are controlled by the gonadotropins follicle-stimulating hormone (FSH) and luteinizing hormone (LH), respectively. While it was suggested that a common secretagogue, gonadotropin-releasing hormone (GnRH), oversees both functions, the generation of loss-of-function fish challenged this view.
