The precise role of seminal proteins in sustaining post-mating responses in fruit flies
Successful reproduction is critical to pass genes to the next generation. In sexually reproducing organisms, sperm enter the female with seminal proteins that are vital for fertility. view more (2007-12-18)
Low sperm count may be associated with prenatal testosterone excess
Exposure to an excess of sexual steroids, like testosterone, during fetal development may be a potential risk factor for low sperm count and motility. view more (2008-09-23)
New microfluidic devices found to be effective method of in-vitro fertilization 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. view more (2005-10-13)
The secret sex life of seaweed revealed
Melbourne researchers have revealed for the first time the sex lives of red seaweed using sophisticated time-lapse video microscopy. "Until now, no one knew what exactly happens when these seaweeds become sexy," says University of Melbourne researcher, Dr Sarah Wilson. "Despite the fact that red seaweed is worth hundreds of millions... view more... (2002-08-18)
Hopes raised for cancer survivors who wish to be fathers
A study at the University of Edinburgh into the fertility of men who have survived chemotherapy and radiotherapy treatment for childhood cancer and leukaemia shows that despite generally low sperm counts , the DNA carried by their sperm appears to be undamaged, posing no increased risk of cancer or congenital defects to their children. And new... view more... (2002-09-03)
New research challenges advice that men should abstain from sex before fertility treatment
Madrid, Spain: New research by Israeli fertility experts has challenged current medical opinion, which holds that refraining from sex for up to a week at least is beneficial for men prior to undergoing some types of fertility treatment. Doctors and scientists from Soroka University and Ben-Gurion University of the Negev, Beer-Sheva, tested over... view more... (2003-06-27)
Sperm proteome gives "tantalising glimpse" towards the origin of sex
The first ever catalogue of the different types of proteins found in sperm could help reveal the origins of sex and explain some of the mysteries of infertility, say scientists. view more (2006-11-13)
Study links high levels of nitric oxide to infertility and sperm DNA damage
Iranian scientists have linked a chemical that plays an essential role in many bodily functions to sperm DNA damage and male infertility. view more (2006-06-19)
Durable critters providing insight for human egg preservation
A tiny, six-legged critter that suspends all biological activity when the going gets tough may hold answers to a better way to cryopreserve human eggs, researchers say. view more (2006-12-19)
Proteins in sperm unlock understanding of male infertility says new study
Proteins found in sperm are central to understanding male infertility and could be used to determine new diagnostic methods and fertility treatments according to a paper published by the journal Molecular and Cellular Proteomics (MCP). view more (2008-10-09)
Mother knows best
Scientists have found new evidence to explain how female insects can influence the father of their offspring, even after mating with up to ten males. view more (2009-09-09)
Daily sex helps to reduce sperm DNA damage and improve fertility
Daily sex (or ejaculating daily) for seven days improves men's sperm quality by reducing the amount of DNA damage. view more (2009-06-30)
Evolutionary phenomenon in mice may explain human infertility
Scientists at the University of Liverpool have found that field mice have evolved a unique way of ensuring faster fertilisation, a phenomenon which could explain some cases of infertility in humans. view more (2008-01-23)
A test to prove a woman has been raped
Stray Y chromosomes can confirm an allegation of rape A TEST that can prove a woman has been raped even if no sperm are found should be widely adopted, the first large-scale study suggests. After the trauma of rape, women who report it have to undergo a medical examination to look for sperm. But the... view more... (2002-02-27)
UVa Scientists Discover New Human Protein Offering Clue To Immune Infertility in Men and Women
Most of us have never heard of immune infertility, yet it prevents many prospective parents from conceiving. view more (2007-09-13)
A new male-specific gene in algae unveils an origin of male and female
By studying the genetics of two closely related species of green algae that practice different forms of sexual reproduction, researchers have shed light on one route by which evolution gave rise to reproduction though the joining of distinct sperm and egg cells. view more (2006-12-19)
Early-stage sperm cells created from human bone marrow
Human bone marrow has been used to create early-stage sperm cells for the first time, a scientific step forward that will help researchers understand more about how sperm cells are created. view more (2007-04-13)
Chromosomal abnormalities in sperm higher after vasectomy reversal
Men who have had a vasectomy reversed have a very much greater rate of chromosomal abnormalities in their sperm than do normal fertile men. view more (2006-06-21)
Is there a risk of transmitting genetic disorders to babies conceived by fertility procedures?
As medical technology continues to advance, fertility procedures such as in-vitro fertilization and donor insemination are becoming more commonplace. view more (2006-05-22)
Studies to find better ways to preserve human eggs, ovarian tissue under way
The goal is to make human eggs, ovarian tissue, blood vessels, even whole organs available when needed. view more (2007-06-07)
