Distribution of cyclic AMP in human seminal plasma and its relation to sperm progressive motility

Scandinavian Journal of Urology and Nephrology
B Stegmayr, G Ronquist


Organelles and amorphous substance (pellet II) isolated from human seminal plasma contained 3'5' AMP (cyclic AMP, cAMP) in manifold smaller amounts than did the particle-free seminal plasma. The amount of cAMP associated with pellet II did not differ significantly between normospermic and oligozoospermic or teratozoospermic ejaculates. In analyses of split ejaculate fractions, the distribution of cAMP coincided with that of fructose and protein (but not with the Mg2+- and Ca2+-dependent ATPase activity or with zinc), indicating secretion of cAMP by the seminal vesicles. The distribution profiles of cAMP in the various ejaculate fractions were similar for particle-free seminal plasma and for pellet II material. The cAMP contents of the fractions were compared with sperm motility in the same fractions. An inverse relationship was found, with the first three fractions displaying higher sperm motility and the last three fractions higher cAMP content.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
