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.

Study provides new insights into Zika's rapid infection and risk for transmission

Study provides new insights into Zika's rapid infection and risk for transmission

Though first documented 70 years ago, the Zika virus was poorly understood when it burst onto the scene in the Americas in 2015. [More]
Researchers confirm long persistence of Zika virus in semen and reveal its presence within spermatozoa

Researchers confirm long persistence of Zika virus in semen and reveal its presence within spermatozoa

Recent work has shown that Zika virus persists in semen for up to 6 months after infection. In a correspondence published in The Lancet Infectious Diseases, the researchers, in addition to confirming its long persistence in semen (in this case for more than 130 days, i.e., over 4 months), reveal the presence of the virus even within spermatozoa.

Endogenous cannabinoid plays crucial role in activating spermatozoa for fertilization

Endogenous cannabinoid plays crucial role in activating spermatozoa for fertilization

During fertilization, a sperm must first fuse with the plasma membrane and then penetrate the female egg in order to penetrate it. [More]

Management of prostate cancer varies by race

A study published in The Journal of Urology® indicates that treatment for low-risk prostate cancer, rather than watchful waiting, is most likely to be sought by black men. [More]

UCLA urologist debunks 5 common myths about vasectomies

Men can be very concerned about what happens during, and after, a vasectomy - specifically how it will affect them personally. Dr. Jesse Mills, a clinical professor of urology and director of The Men's Clinic at UCLA, says the many myths surrounding the procedure can make men rethink what is often a smart choice for them.

PREVAIL IV trial opens in Liberia for EVD survivors with persistent traces of Ebola virus RNA

The Partnership for Research on Ebola Virus in Liberia, a U.S.-Liberia joint Clinical Research Partnership, today announced the opening of PREVAIL IV, a treatment trial for men who have survived Ebola virus disease (EVD) but continue to have evidence of Ebola virus genetic material, RNA, in their semen.

Math professor develops scientific model to report ways Zika virus proliferates

Math professor develops scientific model to report ways Zika virus proliferates

A University of Miami math professor has developed a scientific model to address the various ways the Zika virus proliferates. The study, published June 17, 2016 in Scientific Reports, reveals that mosquito control should remain the most important mitigation method to control the virus. [More]
Sperm of smokers has greater extent of DNA damage than that of non-smokers

Sperm of smokers has greater extent of DNA damage than that of non-smokers

A recent study found that that sperm of men who smoke has a greater extent of DNA damage than that of non-smokers. [More]
Researcher aims to develop easy-to-use, inexpensive sperm sorting devices to help infertile couples

Researcher aims to develop easy-to-use, inexpensive sperm sorting devices to help infertile couples

The competition is fierce and only the strongest survive the obstacle course within the female reproductive tract. Of the millions of sperm that enter the vagina, only about 10 or so make it to the oocyte or egg, demonstrating how rigorous the natural sperm selection process really is. [More]
Study finds link between late onset of puberty and subsequent semen quality in men

Study finds link between late onset of puberty and subsequent semen quality in men

A new study from Rigshospitalet and EDMaRC finds a strong association between late onset of puberty and subsequent semen quality. This is the first study of its kind to investigate the influence of pubertal timing on male reproductive health. [More]

Hepatitis B virus screening for Asian American adults can help prevent onset of liver diseases

A community-based hepatitis B virus screening effort led by UC Davis researchers found that targeted outreach to Asian American populations can identify groups at high risk for infection and direct them to appropriate follow-up care to help prevent the onset of liver diseases, including cancer.

Study sheds light on several aspects of Ebola virus flare-ups in Liberia

Study sheds light on several aspects of Ebola virus flare-ups in Liberia

Ebola virus samples taken from patients in Liberia in June 2015 are strikingly similar in their genetic makeup to other Ebola virus sequences from Western Africa, according to research published online today in the journal Science Advances. The study sheds light on several aspects of the "flare-ups" that have occurred in Liberia since the country was initially declared free of Ebola virus disease. [More]
