Baby born from sperm frozen for record 21 years
UK researchers writing in Europe's leading reproductive medicine journal Human Reproduction[1], today (Tuesday 25 May) report what they believe to be a world record - a baby born using sperm that had been frozen for 21 years. "We believe this is the longest period of sperm cryopreservation resulting in a live birth so far reported in the... view more... (2004-05-23)
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)
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)
Unlocking the key to human fertility
Scientists at Leeds and Bradford have discovered a unique 'DNA signature' in human sperm, which may act as a key that unlocks an egg's fertility and triggers new life. view more (2009-08-03)
Human sperm created from embryonic stem cells
Human sperm have been created using embryonic stem cells for the first time in a scientific development which will lead researchers to a better understanding of the causes of infertility. view more (2009-07-08)
Possible Genetic Factor for Male Infertility Identified
Virginia Commonwealth University School of Medicine researchers have discovered a gene involved with the production of sperm that may contribute to male infertility and lead to new approaches to male contraception. view more (2009-09-16)
USC researchers explore genetic causes for male infertility
Researchers at the University of Southern California (USC) suggest epigenetics, or the way DNA is processed and expressed, may be the underlying cause for male infertility. The study will be published in the Dec. 12 issue of Public Library of Science One. view more (2007-12-12)
Males have adapted to battle with competing sperm
In the context of sexual reproduction, natural selection is generally thought of as a pre-copulation mechanism. We are drawn to features of the human body that tell us our partner is healthy and will provide us a fighting opportunity to carry on our genetic lineage. view more (2007-02-12)
Researchers Examine Protein Vital to Reproduction Process, Regulation May Increase Chances of Pregnancy
In its early and most critical stages, human reproduction requires precise, vital functions. The role of one sperm-delivered protein, which is crucial to the process, is being closely observed by scientists from the United States and Canada. Lab tests in recent years have produced valuable information and hopes of regulating that protein to... view more... (2007-03-20)
Spread your sperm the smart way
Attractive males release fewer sperm per mating to maximise their chances of producing offspring across a range of females, according to a new paper on the evolution of ejaculation strategies. view more (2009-07-09)
Gene defects could be new cause of male infertility
Scientists at the University of North Carolina at Chapel Hill have identified a gene crucial to the final step of the formation of a functional sperm cell. view more (2007-10-18)
