Unleashing the pharmacological potential of taste receptors in reproductive processes beyond their gustatory role.

Traditionally, taste receptors (TRs) have been understood to reside within the taste buds on the tongue, serving as initiators for different taste perceptions. However, recent research has expanded our understanding, revealing that TRs are found throughout the body and perform a wide range of functions beyond taste perception as non-tasting functions. These receptors, along with their genetic variations, have been linked to various human health conditions. They are activated by an array of substances, including hormones, nutrients, and toxins, indicating their involvement in numerous biological processes. Specifically, in males, TRs are notably present in the testes and epididymis, where they contribute to the hormonal production, spermatogenesis, and sperm maturation. In females, these receptors are found in the ovaries, uterus, and myometrium, playing crucial roles in ovulation, menstrual cycle regulation, and embryo implantation. There are a lot of missed areas regarding TRs research that imposes to fulfill the gaps in the current understanding of their role in reproduction. This review aims to provide a comprehensive overview of the emerging roles of extraoral TRs in reproductive health, highlighting their physiological and pathophysiological significance in various reproductive processes. As well, grabbing the attention towards the release of new pharmacological interventions to manage conception and contraception in male and female was considered.
