Researchers Discover World’s Oldest Petrified Sperm In Australian Cave
2014-05-15 07:40:11

redOrbit Staff & Wire Reports – Your Universe Online An international team of researchers working at a fossil site in northwest Queensland, Australia have come across a remarkable, unusual and perhaps even somewhat icky find – the world’s oldest petrified sperm sample. According to reports published by NBC News, the sperm came from a tiny crustacean known as an ostracod and dates back somewhere between 16 million and 23 million years to the early Miocene epoch. An ostracod,...

Male Fertility Relies On A Key Protein That Also Protects Against Disease
2014-05-13 10:58:14

Brett Smith for redOrbit.com - Your Universe Online Male infertility prevents many couples from being able to conceive a child and a new study published in the journal Nature Communications has found a specific protein that is a major determining factor in determining a sperm’s ability to fertilize an egg. The protein, known as Chd5, is responsible for effectively packaging DNA inside the head of a sperm, where space it at a premium. Each cell in the body contains an entire copy of...

New Findings Could Lead To Novel Diagnostic Tests And Treatments For Male Infertility
2014-02-19 10:38:25

American Institute of Physics To better understand the causes of male infertility, a team of Bay Area researchers is exploring the factors, both physiological and biochemical, that differentiate fertile sperm from infertile sperm. At the 58th Annual Biophysical Society Meeting, which takes place Feb. 15-19, 2014, in San Francisco, Calif., the team will present its work to identify and characterize proteins known as ion channels, which are crucial for sperm fertility and expressed within a...

Plasma protein fetuin-B regulates hardening of the zona pellucida and thus ensures the fertilization capacity of the ovum Scientists in Mainz and Aachen have discovered a new mechanism that controls egg cell fertility and that might have future therapeutic potential. It was revealed by Professor Dr. Walter Stöcker of the Institute of Zoology at Johannes Gutenberg University Mainz (JGU) that the blood protein fetuin-B plays an important and previously unknown role in the...

Hyper And Micro-gravity Affect Processes Involved In Reproduction, Brain Diseases And Cancer
2013-03-14 12:12:58

University of Montreal University of Montreal researchers found that changes in gravity affect the reproductive process in plants. Gravity modulates traffic on the intracellular "highways" that ensure the growth and functionality of the male reproductive organ in plants, the pollen tube. "Just like during human reproduction, the sperm cells in plants are delivered to the egg by a cylindrical tool. Unlike the delivery tool in animals, the device used during plant sex consists of a single...

Sperm Count, Quality In Men Lower Now Than Two Decades Ago
2012-12-05 12:26:58

Lawrence LeBlond for redOrbit.com - Your Universe Online Male fertility is one of the most controversial issues in medical science. Recent studies have shown that some chemicals can harm male fertility while others have shown foods that actually boost it. Despite all the science, it seems sperm counts in men are dropping all around the world. And no place seems more threatened by sperm loss than France. In a new study reported in the journal Human Reproduction, French researchers have...

Secret To Fitness For Toad Sperm Is To Mate Frequently

University of Veterinary Medicine, Vienna An increasing number of men suffer from fertility problems, especially in western society. The general belief is that many problems may be related to stress but it is possible that some of them may arise because men simply have intercourse too infrequently. This is the intriguing implication of recent research at the University of Veterinary Medicine, Vienna, that has just been published in the international online journal PLoS ONE. Fertility...

Researchers find that gene related to germ cell formation is far older than first thought Harvard scientists have solved the long-standing mystery of how some insects form the germ cells — the cellular precursors to the eggs and sperm necessary for sexual reproduction — and the answer is shedding new light on the evolutionary origins of a gene that had long been thought to be critical to the process. As described in a November 1 paper published in Current Biology, a team of...

New Technique Allows Scientists To Track Sperm Movements
2012-09-18 14:50:46

Lee Rannals for redOrbit.com — Your Universe Online A new imaging technique is allowing scientists to get more up close and personal than ever before with human sperm. UCLA researchers developed an imaging technique allowing them to track the movements of 1,500 human sperm at one time in 3D. Imaging moving objects like sperm has been difficult to do through microscopes and other tools, so scientists developed the new technique to watch sperm like never before. The new...
