Screening test would give hope to childless couples

According to new research thousands of childless British couples could greatly improve their chances of having a baby if a test that weeds out faulty embryos were carried out.

Fertility treatment most successful in summer

When it comes to considering fertility treatment, scientists say that women who have the treatment during the summer are twice as likely to become pregnant as those who have it in the winter.

Men who smoke cigarettes may experience a significant decline in their capacity to father a child

Sperm from nearly two-thirds of the chronic smokers in the study failed a special test that measures the ability of sperm to fertilize an egg. On average, those men showed a 75 percent decline in fertilizing capacity when compared to nonsmokers. Lead researcher Loni Burkman, Ph.D., presented the results today (Oct. 17, 2005) at the American Society of Reproductive Medicine annual meeting in Montreal, Quebec.

Alternative methods to create stem cells successful in mice-studies

According to researchers in the U.S. two alternative methods for making embryonic stem cells, work in mice and could lead to a less controversial way to grow them.

Microfluidics can be used successfully for IVF in mice

Technology that more closely mirrors the natural fertilization process is showing promise as a new method of in-vitro fertilization, researchers at the University of Michigan Health System have found.

Israeli scientists successfully transplant ovaries in sheep and trigger early embryonic development

Israeli scientists report in Human Reproduction that they have successfully transplanted whole frozen and thawed ovaries in sheep, retrieved oocytes from these ovaries and triggered them in the laboratory into early embryonic development.

85 percent of embryos transferred during in vitro fertilization fail to become live births

Published in the August issue of Fertility and Sterility, the study reviewed seven years of U.S. statistics from all the fertility clinics that report data on reproductive techniques.

Workshop - stem cells in reproduction and in the brain

"Once we have found the factors by which body cells can be re-programmed into stem cells, then therapeutic cloning might become superfluous," said Hans R. Scholer, director of the Max Planck Institute for Molecular Biomedicine in Munster, Germany, at an international scientific symposium on stem cell research in Kobe, Japan.

Nitric oxide could one day help women in their 30s and 40s remain fertile longer

Researchers have found that an important chemical compound, nitric oxide, appears to slow or reverse the aging of eggs in mouse ovaries. The finding suggests nitric oxide could one day help women in their 30s and 40s remain fertile longer and increase their chances of having healthy babies, the scientists say.

New ways to enhance or block fertilization

Researchers have capitalized on the unique properties of a sperm cell to follow cell membrane fusion as it occurs during fertilization, tracking the full cascade of events for the first time. The findings could reveal new ways to enhance or block fertilization, as well as how to control the secretion of neurotransmitters and hormones such as insulin.

FDA dragging its heels yet again over 'morning after' pill Plan B

Women in the U.S., unlike their counterparts in the UK and other countries, will still be denied easy access to the 'morning after' contraceptive pill, Plan B, after a decision by the Food and Drug Administration to yet again delay ruling on over-the-counter sales.

Placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases as embryonic stem cells

Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells, suggests a University of Pittsburgh study to be published in the journal Stem Cells and available now as an early online publication in Stem Cells Express.

MicroRNAs play an important role in regulating oogenesis

Researchers at Northwestern University and Carnegie Mellon University have found that a recently described class of molecules called microRNAs (miRNAs) play an important role in regulating oogenesis, the process by which females make eggs.

Relationship between allergies and mold spores in lawns

"Have you ever driven down the road and seen someone mowing the lawn wearing a mask? This is an example of the relationship between allergies and mold spores in lawns. Dr. Phil Colbaugh, research plant pathologist at the Texas Agricultural Experiment Station in Dallas, cites a common image seen in Texas throughout the warm weather months.

IVF treatment to restrict women to one embryo only each time

In order to avoid the dangers of multiple births, women having in vitro fertilisation may be limited to having just one embryo implanted at a time.

University of Florida researcher finds way to explore role of microRNAs in specific tissue

University of Florida researchers have learned how to selectively shut down a flyweight-sized genetic molecule that packs a heavyweight punch, a discovery that may help doctors better understand cancer, birth defects and other health problems.

Scientists determine the structures of eight proteins in just 10-20 days per protein

A University at Buffalo scientist created a stir in 2003 when he announced a much faster, more precise and far less expensive method of obtaining nuclear magnetic resonance (NMR) data to map a protein's atomic structure. Genomics researchers were fascinated, but some also were a bit skeptical.

Cigarette smoke stops transport of freshly ovulated hamster eggs

Eggs of female hamsters are significantly less likely to be transported by the oviduct when the eggs or the oviduct have been exposed to cigarette smoke, and this could result in disruption of fertilization and pregnancy, according to reproductive scientists at the University of California, Riverside.

Sexual abstinence unrealistic - pediatricians say teens need birth control and emergency contraception pill

In complete contrast to the abstinence-only approach to sex education favored by religious groups and President Bush, an eminent group of pediatricians is saying that what todays' teenagers need is better access to birth control and emergency contraception.
