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.

Targeting proteins in semen could prevent sexually transmitted spread of Ebola virus

Protein fragments, called amyloid fibrils, in human semen significantly increase Ebola virus infection and protect the virus against harsh environmental conditions such as heat and dehydration. Researchers from the Perelman School of Medicine at the University of Pennsylvania report these findings in a study published this week in the Proceedings of the National Academy of Sciences.

Prostate cancer on the rise and detected late in the UK finds report

As many as 37 percent of all prostate cancers are detected late or in advanced stages in the UK, finds a new report from the charity Orchid. The report suggests that most of these cancers are detected at stages 3 and 4. Statistics show that nearly 47,000 men are diagnosed with prostate cancer annually and 11,000 succumb to the disease each year.

Home-based semen analysis kit could provide rapid, cost-effective way to test male fertility

It is estimated that of the 70 million cases of infertility worldwide, almost half are caused by factors relating to the male partner. A number of semen parameters – motility, morphology, velocity, volume, concentration, and count – affect male fertility.

One or more sugar-sweetened beverages per day linked to lower chance of getting pregnant

The amount of added sugar in the American diet has increased dramatically over the last 50 years. Much of that increase comes from higher intake of sugar-sweetened beverages, which constitute approximately one-third of the total added sugar consumption in the American diet.

Study provides insights into how obesity may contribute to male infertility

A new study sheds light on how obesity may contribute to male infertility. Published in open-access journal Frontiers in Physiology, the study reports that obese men have increased levels of inflammatory markers in their seminal fluid and lower sperm quality, both of which correlate with their body mass index.

Epigenetics: A New Tool for Forensic Detectives

Developing analytical methods can help the triers of fact, judges and juries, better understand the events surrounding the circumstances of a crime. In forensic analysis, we are talking about determining the identity of unknown individuals through DNA and using DNA and other chemical signatures to determine and clarify the circumstances of the crime.

New insights into mosquito sex protein could provide strategies to control diseases

If you thought the sex lives of humans were complicated, consider the case of the female Aedes aegypti mosquito, bringer of Zika, dengue, and yellow fever: She mates but once, in seconds and on the wing, with one lucky male; spurns all further advances from other potential suitors; and stores enough sperm from that single encounter to lay more than 500 eggs, which she nourishes with the blood of human hosts.
