Luteinizing hormone is synthesised in the pituitary and travels the body in a glycosylated form (Riccetti et al., 2017). As the image on the left shows, luteinizing hormone plays a role in ovulation and the maturation of follicles in females (Riccetti et al., 2017). In males, luteinizing hormone is responsible for the synthesis of testosterone from the leydig cells (Riccetti et al., 2017). This hormone has an alpha subunit identical to that of follicle-stimulating hormone and a beta subunit (Riccetti et al., 2017). This structure is typical of most glycoproteins (Riccetti et al., 2017).
