Anti-Müllerian hormone (AMH), also known as Müller duct inhibitory factor and primarily known for its role in sexual differentiation. In female fetuses, AMH production by granulosa cells begins around the 36th week of gestation and continues in women until menopause. It is becoming more significant in the endocrine and gynecological diagnosis of adult women.

Background: Erectile dysfunction (ED) is a prevalent male sexual disorder, commonly associated with hypertension, though the underlying mechanisms remain poorly understood.
Objective: This study aims to explore the role of Fatty acid synthase (Fasn) in hypertension-induced ED and evaluate the therapeutic potential of the Fasn inhibitor C75.
Materials And Methods: Erectile function was assessed by determining the intracavernous pressure/mean arterial pressure (ICP/MAP) ratio, followed by the collection of cavernous tissue for transcriptomic and non-targeted metabolomic analyses.

Communication is crucial for mate choice and thus for the survival and fitness of most species. In the cricket, females choose males according to their calling-song attractiveness and, exhibiting positive phonotaxis they approach the chosen male. Light has been widely reported to induce changes in crickets' daily activity patterns, including the males' stridulation behavior.

Bacterial vaginosis (BV), characterized by an imbalance in the vaginal microbiota, is a prevalent condition among women of reproductive age and a risk factor for human immunodeficiency virus, sexually transmitted infections, and preterm birth. BV is generally considered to induce mucosal inflammation, but the specific pathways and cell types involved are not well characterized. This prospective study aimed to assess associations between microbial changes and mucosal immune responses in BV patients.

In mammals, differentiation of germ cells is crucial for sexual reproduction, involving complex signaling pathways and environmental cues defined by the somatic cells of the gonads. This review examines the long-standing model positing that all-trans retinoic acid (ATRA) acts as a meiosis-inducing substance (MIS) in the fetal ovary by inducing expression of STRA8 in female germ cells, while CYP26B1 serves as a meiosis-preventing substance (MPS) in the fetal testis by degrading ATRA and preventing STRA8 expression in the male germ cells until postnatal development. Recent genetic studies in the mouse challenge this paradigm, revealing that meiosis initiation in female germ cells can occur independently of ATRA signaling, with key roles played by other intrinsic factors like DAZL and DMRT1, and extrinsic signals such as BMPs and vitamin C.
