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.

Uncomplicated twin pregnancies might be more risky than previously thought

As mothers get older and assisted conception becomes more common, the incidence of multiple births - primarily of nonidentical siblings, but also of identical ones - has dramatically increased.

Infertility may be becoming more of a man's problem than a woman's problem

Until now, approximately 40% of infertility cases have been linked to medical problems in men and 40% to medical problems in women, with the remaining 20% due to joint problems.

Chemicals found in everyday products and food have subtle but potentially damaging effects on sperm fertility

Professor Lynn Fraser told the 21st annual conference of the European Society of Human Reproduction and Embryology today (Wednesday), that her previous research had shown that certain chemicals known to mimic the female sex hormone, oestrogen, could individually affect the correct functioning of mouse sperm, but now her new research showed that when the chemicals were combined they had an even stronger effect.

Australian researchers develop process that causes embryonic stem cells to develop into ovarian structures containing eggs

The researchers believe the process could in future be used to develop eggs for sterile women that contain the women's own genetic material.

Damage to DNA in sperm is significantly higher in older men

Damage to DNA in sperm is significantly higher in older men than in those who are younger, according to research presented today (Tuesday 21 June 2005) at the 21st annual conference of the European Society of Human Reproduction and Embryology.
