Kisses can be therapies helping to promote fertility in women! When women were administered Kisspeptin, which is a hormone produced by the “KISS-1” gene, ovulation and fertility was restored in a few. This can be a very good news for women with low sex hormone levels. Animals and humans lacking this kisspeptin hormone do not go through puberty and remain sexually immature, and this is in favour of this new research finding. Kisspeptin is basically the product of the KISS-1 gene and it is a G-protein coupled receptor ligand for GPR54. KISS-1 gene was originally identified as a gene that has the ability to suppress melanoma and breast cancer metastasis. However, several studies have made it clear that kisspeptin-GPR54 signaling has a significant role in initiating secretion of gonadotropin-releasing hormone (also called as luteinizing-hormone) at puberty. Kisspeptin hormone activates the release of sex hormones, which are responsible for controlling the menstrual cycle. Well, this field has several ongoing research studies.

One thing that is very interesting about this KISS-1 gene is the history behind its naming! The naming of the KISS-1 gene and Kisspeptin, was made by a team of researchers, who discovered the gene in Hershey, Pennsylvania, famous for its chocolate “Hershey’s Kisses” (bite-sized pieces of chocolate manufactured by The Hershey Company).
