Sperm olfactory receptors

7 Jan The detection of external cues is fundamental for human spermatozoa to locate the oocyte in the female reproductive tract. This task requires a specific chemoreceptor repertoire that is expressed on the surface of human spermatozoa, which is not fully identified to date. Olfactory receptors (ORs) are.

23 Jan The estimated number of testicular olfactory receptors (ORs) in mammals range between 20 and Previous data reported the role of hOR and mOR23 in sperm–oocyte chemiotaxis. Proteomic analysis was performed to understand which are the ORs expressed in seminal plasma.

Seminal samples.

26 Sep It turns out sperm don't just swim blindly, hoping to randomly bump into eggs. Instead, like bacteria, sperm can sense their chemical environment and adjust their swimming accordingly.

Sperm have a sense of smell. The (g-protein coupled) olfactory receptors in our noses that activate our sense of smell. Olfactory receptors (ORs), also known as odorant receptors, are expressed in the cell membranes of olfactory receptor neurons and are responsible for the detection of odorants which give rise to the sense of smell. Activated olfactory receptors trigger nerve impulses which transmit information about odor to the brain.
