Male infertility is where a man has a lower chance of impregnating his female partner if at all, leading to exhausting, and sometimes disappointing, treatment involving artificial or in vitro … Continue Reading Human sperm stem cells grown in lab, an early step toward treating male infertility.
In genetic engineering and fertility, sperm sorting is a technique allowing the selection of the type of sperm cell to fertilize the egg cell with. It can be used to … Continue Reading Cheap, simple technique allows sex selection of sperm before fertilization.
Infertility affects up to 15% of couples, with roughly one-third of all cases being caused by male infertility. One major cause of male infertility is the failure of precursor germ … Continue Reading Stem cell technique makes first ever viable sperm-in-a-dish.
Semen quality is a measure of the ability of semen to accomplish fertilization and a measure of fertility in a man. It is the sperm in the semen that are … Continue Reading ‘Spermbots’ successful in proof-of-concept fertility studies.
A fundamental law of genetics states that progenies do not inherit epigenetically-based adaptive, pathological or neural features acquired in response to environmental conditions. However, recent studies seem to contradict this … Continue Reading Researchers map ‘epigenetic inheritability’ in fathers sperm caused by diet.
Obesity is a metabolic disorder resulting from behavioral and heritable causes. Children of obese fathers are at higher risk of developing metabolic disease later in life, independent of the body … Continue Reading Study maps epigenetics of father’s weight passed on by his sperm.
It has long been known that there is a linear connection between sperm motility and chances of becoming pregnant. Sperm motility describes the ability of sperm to move properly through … Continue Reading Study finds lower sperm motility in men exposed to a common, everyday chemical.
IVF, or in vitro fertilization, currently has a 32 percent success rate, and couples for whom the procedure fails face the puzzling, disappointing reality that they can’t have a child … Continue Reading Researchers identify previously unknown mechanism of human fertilization.
In male fertility normal sperm cells have an oval-shaped head with a cap-like covering called the acrosome. The acrosome contains enzymes that break down the outer membrane of an egg … Continue Reading Researchers identify new architecture and mechanism in the human sperm.
In the most severe form of male infertility, men do not make any measurable levels of sperm. This condition, called azoospermia, affects approximately 1 percent of the male population and … Continue Reading Researchers identify a new gene responsible for male infertility.
In a small study, Johns Hopkins researchers found that DNA from the sperm of men whose children had early signs of autism shows distinct patterns of regulatory tags that could … Continue Reading Epigenetic tags on DNA from fathers’ sperm linked to children’s autism symptoms.
Researchers at the Weizmann Institute of Science and Cambridge University have jointly managed the feat of turning back the clock on human cells to create primordial germ cells, the embryonic … Continue Reading Human primordial cells programmed in the lab for the first time.
A new study from the University of Gothenburg has identified the key molecule ‘Greatwall kinase’ which protects women’s eggs against problems that can arise during the maturation process. The study … Continue Reading Researchers identify molecule that protects women’s eggs.
