Sperm quality may impact offspring

Men who wait longer to have children run an increased risk of passing on potential health conditions to their offspring due to sperm health, a new study from University of Otago has found. The study analyzed the results of 90 existing studies on male fertility and found consistent findings—the quality of a man’s semen declined as he aged. It’s already recognized that a woman’s age can lead to increased likelihood of health problems in children but it has been less [...]

Being in a developed country will not develop your sperm

Being in a developed country will not develop your sperm. In recent years, scientists mention more and more about the effects caused by chemical substances (natural or anthropogenic origin) disrupting the reproductive functions in wildlife. This finding is illustrating the growing concern of the society, that exposure to toxic substances in the environment could have negative effects on human fertility with more and more people are having issues to conceive. As the famous journalist Michael Pollan Said “We are what we [...]

Testing sperm on the go? Tool goes mobile in 2015

One of every five men has low-sperm counts that can impair conception. The researchers Greg Sommer and Ulrich Schaff decided to shed some light on fertility changes in men. Their invention “TrakFertility” will allow for men to self-test for sperm quality. In just 5 minutes with a few drops of semen. "It would be like using a scale to follow weight, only in this case, men would track changes in their fertility," Sommer said. "We want to help people conceive in a [...]

Big sperm don’t always win the race

When females mate with more than one male, each one's sperm has to compete to get to her eggs. Until now, researchers had thought the fastest sperm would dominate.But in a new study, published in Evolution, a team of scientists have found that it is much more complicated than that.'If you compare species with little sperm competition, like humans, with a species where there is a lot of sperm competition, like Bonobos, then the bonobos tend to have faster, bigger sperm,' says Dr [...]

Sperm finding could improve fertility, contraceptives

(Medical Xpress)—A new study headed up by Cornell scientists has found that a component of the sperm membrane tightly controls a crucial step in fertilization, making it a prime target for efforts to either assist fertilization or prevent it.That's good news for both fertility efforts and contraceptive development, according to lead author Dr. Alexander Travis, associate professor of reproductive biology at Cornell's Baker Institute for Animal Health and the College of Veterinary Medicine.He and his colleagues report in the [...]

The secret of fertile sperm

To better understand the causes of male infertility, a team of Bay Area researchers has been exploring the factors, both physiological and biochemical, that differentiate fertile sperm from infertile sperm. At the 58th Annual Biophysical Society Meeting, which took place Feb. 15-19, 2014, in San Francisco, Calif., the team presented its work to identify and characterize proteins known as ion channels, which are crucial for sperm fertility and expressed within a sperm cell's plasma membrane."Any knowledge gained in this area may [...]

Lab Grown Sperm Could Cure Male Infertility

Sperm has been successfully grown in a test tube for the first time, a breakthrough technology that could eventually help cure male infertility, Japanese scientists said Thursday.In the experiment, researchers at Yokohama City University were able to produce healthy, fertile offspring using the laboratory created sperm. Their findings can be found in the journal Nature.“Until now, none of the attempts have been wholly successful, and when the sperm have been used, the pups born have not been healthy and have soon [...]

Sticky spermatozoa could hold fertility key

Researchers from the University of Leeds think that sticky spermatozoa could hold the key to greater success for couples undergoing IVF treatment.The largest clinical trial to date aimed at testing this idea is being launched October 28th, the first day of National Infertility Awareness Week.The £1.3m trial, funded by the National Institute for Health Research Efficiency and Mechanism Evaluation (NIHR EME) Programme, will be piloting a new IVF method that relies on picking only mature and fertile spermatozoa that [...]

Frozen sperm as good as fresh for IVF treatment

A recent study published in PLOS ONE finds that frozen sperm retrieved via testicular biopsy is as good as fresh sperm in leading to a successful pregnancy through IVF. The finding should make it easier to organize IVF procedures and increase options for infertile couples.IVF (in vitro fertilization) is a technique that helps couples with fertility problems to have a baby. During the procedure, an egg is removed from the woman's ovaries, fertilized in a lab dish with sperm from the [...]
