Semen is an organic fluid, also known as seminal fluid, that usually contains spermatozoa. It is secreted by the gonads (sexual glands) and other sexual organs of male or hermaphroditic animals and can fertilize female ova. The process of discharge is called ejaculation.
Reducing amyloid fibril levels in semen may help reduce transmission of HIV

Reducing amyloid fibril levels in semen may help reduce transmission of HIV

There may be two new ways to fight AIDS -- using a heat shock protein or a small molecule - to attack fibrils in semen associated with the human immunodeficiency virus (HIV) during the initial phases of infection, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

Researchers develop sperm RNA diagnostic test to help determine best infertility treatment for couples

Researchers develop sperm RNA diagnostic test to help determine best infertility treatment for couples

A Wayne State University School of Medicine professor, in collaboration with researchers at CReAte Fertility Center, University of Toronto, Harvard University and Georgia Reagents University, has developed the first diagnostic test for sperm RNA based on next-generation sequencing. For couples with unexplained infertility, the test may help determine the best infertility treatment for couples having difficulty conceiving. [More]
New study launched in Liberia to better understand health consequences of Ebola virus disease

New study launched in Liberia to better understand health consequences of Ebola virus disease

The Liberia-U.S. clinical research partnership known as PREVAIL has launched a study of people in Liberia who have survived Ebola virus disease (EVD) within the past two years. The study investigators hope to better understand the long-term health consequences of EVD, determine if survivors develop immunity that will protect them from future Ebola infection, and assess whether previously EVD-infected individuals can transmit infection to close contacts and sexual partners.

Study analyses advantages of using fractions of ejaculate in IVF

Study analyses advantages of using fractions of ejaculate in IVF

Sperm in the first fraction of ejaculate are more numerous, move more and present better quality DNA than those lagging behind. This is the conclusion of a study led by the Ginemed fertility clinic, which confirms that while the objective of the first fraction is to fertilise the egg, the second phase is so that no sperm from any other male has a chance to fertilise it.

High levels of pesticide residues in fruits, vegetables can affect semen quality

High levels of pesticide residues in fruits, vegetables can affect semen quality

Men who ate fruits and vegetables with higher levels of pesticide residues—such as strawberries, spinach, and peppers—had lower sperm count and a lower percentage of normal sperm than those who ate produce with lower residue levels, according to a new study by researchers at Harvard T.H. Chan School of Public Health. [More]

Study: ICSI technique no better than conventional IVF

Study: ICSI technique no better than conventional IVF

The use of an assisted reproduction technique known as intracytoplasmic sperm injection (ICSI) doubled between 1996 and 2012, although compared with conventional in vitro fertilization (IVF), use of ICSI was not associated with improved reproductive outcomes, according to a study in the January 20 issue of JAMA.

Study links poor semen quality to higher risk of various health conditions

Study links poor semen quality to higher risk of various health conditions

A study of more than 9,000 men with fertility problems has revealed a correlation between the number of different defects in a man's semen and the likelihood that the man has other health problems. [More]
Exposure to chemicals used in UOG operations may affect reproductive and developmental health

Exposure to chemicals used in UOG operations may affect reproductive and developmental health

Unconventional oil and gas (UOG) operations combine directional drilling and hydraulic fracturing, or "fracking," to release natural gas from underground rock. Recent discussions have centered on potential air and water pollution from chemicals used in these processes and how it affects the more than 15 million Americans living within one mile of UOG operations.

Prenatal exposure to phthalate DiNP associated with shorter AGD in Swedish boys: Study

Prenatal exposure to phthalate DiNP associated with shorter AGD in Swedish boys: Study

The first study to examine prenatal exposure to the phthalate DiNP finds it is associated with a shorter anogenital distance (AGD) in Swedish boys at the age of 21 months. These findings raise concern since animal research has linked DiNP exposure to a shorter AGD, and studies on humans have related shorter AGD to male genital birth defects as well as impaired reproductive function in adult males, and the levels of DiNP metabolites in humans are increasing globally.
