Research explores the role of ATP as a potential neurotransmitter in stimulating kisspeptin neurons to induce ovulation in rodents. The findings shed light on the neurobiological mechanisms involved in ovulation and may have implications for understanding and treating ovulation disorders. ....

New approach could treat infertility caused by abnormal GnRH secretion Reports suggest that at least 25% of ovarian disorders are due to dysfunction of the brain mechanism in the hypothalamus that controls the gonadotropin-releasing hormone (GnRH), which is a molecule that governs the reproductive function in men and women by regulating the release of a range of reproductive hormones into the body, particularly gonadotropins, from the pituitary gland, which is located underneath the brain. In a healthy individual, GnRH and gonadotropins are released in pulses, while typically in individuals whose infertility is caused by hypothalmic dysfunction, the GnRH and gonadotropin pulses are supressed. ....
E-Mail IMAGE: This study has found that KNDy neurons are key to controlling ovarian function in mammals. These neurons express signalling molecules (peptides) in the brain that stimulate pulses of a hormone. view more Credit: Sho Nakamura Gonadotropins are any hormones that are released from the anterior pituitary to stimulate the gonads, or sex glands, to carry out their reproductive functions. The gonadotropin-releasing hormone (GnRH) is therefore fundamental for mammalian reproduction. In a healthy reproductive system GnRH is produced by the brain in pulses. Reports suggest that at least 25% of ovarian disorders are due to dysfunction of the brain mechanism controlling the release of gonadotropins, which is a kind of reproductive disorder associated with the hypothalamus. ....
