The term sperm refers to the male reproductive cells. In the types of sexual reproduction known as anisogamy and oogamy, there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell.

Eurofins successfully completes genetic and forensic research project on twins

Increased inflammation in prostate may predict reduced risk for cancer

Doctors at the North Shore-LIJ Health System have discovered that increased inflammation in the prostate may predict reduced risk for prostate cancer. The findings are published online in CANCER.

Research explores epigenetic effects that contribute to psychiatric disorders in offspring

Advanced paternal age has been associated with greater risk for psychiatric disorders, such as schizophrenia and autism. With an increase in paternal age, there is a greater frequency of certain types of mutations that contribute to these disorders in offspring.

Tet1 helps erase epigenetic imprints from genome ahead of egg, sperm development

A protein called Tet1 is partly responsible for giving primordial germ cells a clean epigenetic slate before developing into sperm and egg cells, according to a new study by researchers at Boston Children's Hospital.

Study sheds new light on neuropsychiatric disorders

Trauma can scar people so indelibly that their children are affected. History provides examples of generations traumatized by war and starvation, whose children experience altered physiology.

New male contraceptive pill could soon be available

A new male contraceptive could be on the horizon after scientists identified a novel way to block the transport of sperm during ejaculation.

New genetics promises to change faulty genes of future generations by using "designer sperm”

Bethesda, MD-Get ready: The "new genetics" promises to change faulty genes of future generations by introducing new, functioning genes using "designer sperm." A new research report appearing online in The FASEB Journal, shows that introducing new genetic material via a viral vector into the sperm of mice leads to the presence and activity of those genes in the resulting embryos.

Oxford scientists use nanoparticles to study mechanisms underlying 'mystery' cases of infertility

A way of using nanoparticles to investigate the mechanisms underlying 'mystery' cases of infertility has been developed by scientists at Oxford University.

Conceive Plus Fertility Personal Lubricant receives FDA approval

The Pew Research Center reports that in the year 2011, the birth rate in the United States slid by 8%. That kind of statistic would indicate getting pregnant isn't as easy as it used to be. However, pharmaceutical manufacturer SASMAR aims to be at the forefront of helping couples to start families. The FDA has officially approved their OTC sperm friendly fertility personal lubricant, Conceive Plus for sale in the US market.

Life events influence genes important for memory and drug use

New human and animal research released today demonstrates how experiences impact genes that influence behavior and health. Today's studies, presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health, provide new insights into how experience might produce long-term brain changes in behaviors like drug addiction and memory formation.

Father's cocaine use may make sons less sensitive to drug and more likely to resist addictive behaviors

A father's cocaine use may make his sons less sensitive to the drug and thereby more likely to resist addictive behaviors, suggests new findings from an animal study presented by Penn Medicine researchers at Neuroscience 2013, the annual meeting of the Society for Neuroscience.

Advanced prostate cancer therapies: an interview with Dr. Nancy Dawson, Lombardi Comprehensive Cancer Center

The prostate gland produces part of the seminal fluid that protects sperm. It is located in front of the rectum and under the bladder, and surrounds the urethra, the tube through which urine flows from the bladder to and out of the penis.

Scientists develop 3D filming technique that reveals spread of malaria

Scientists have developed a 3D filming technique that could help inform research to stem the spread of malaria.

Offspring born to stressed mothers show stress-induced changes

Children of survivors of extremely stressful life events face adjustment challenges of their own, as has been most carefully studied among the children of Nazi Death Camp survivors. This "intergenerational" transmission of stress response has been studied predominately from the psychological perspective. However, recent research points to biological contributions as well.

Researchers receive grant to develop new device that identifies healthy sperm cells for IVF

The World Health Organization estimates more than 70 million couples worldwide are unable to conceive each year, with close to a third of those cases attributable solely to issues with male fertility-including low sperm count and low sperm motility (a limited ability to swim).

New understanding of sperm capacitation may improve IVF success rates

Two new papers from reproductive biologists at the University of Massachusetts Amherst, with international partners, report advances in understanding the basic processes of sperm capacitation that may one day improve success rates of in vitro fertilization (IVF) by providing a shortcut to bypass problems, and may eventually lead to a male contraceptive.

Nutrition tips for women looking to conceive

Women who watch their weight and closely follow a Mediterranean-style diet high in vegetables, vegetable oils, fish and beans may increase their chance of becoming pregnant, according to dietitians at Loyola University Health System.

FDA approves OTREXUP injection for adults with RA, children with active pJIA

Antares Pharma, Inc. today announced the approval of OTREXUP (methotrexate) injection by the U.S. Food and Drug Administration. OTREXUP is the first FDA approved subcutaneous methotrexate for once weekly self-administration with an easy-to-use, single dose, disposable auto injector.

Individuals diagnosed with ASD more likely to have gene deletions, shows analysis

Using powerful genetic sequencing technology, a team of investigators, led by researchers at the Icahn School of Medicine at Mount Sinai, scanned the genome of hundreds of individuals, and discovered those diagnosed with autism spectrum disorder (ASD) were more likely to have gene deletions than were people without the disorder.

Researchers make progress in understanding traits and processes that influence fertilization success

Female promiscuity-something that occurs in a majority of species, including humans-results in the ejaculates from two or more males overlapping within her reproductive tract. When this happens, sperm compete for fertilization of the female's eggs. In addition, the female has the opportunity to bias fertilization of her eggs in favor of one male's sperm over others.
