Just months after Japanese fertility scientists created artificial sperm from stem cells to make baby mice, German and Israeli researchers are making a major breakthrough of their own that could soon see human sperm grown in the laboratory. The development could soon give infertile men the ability to father their own children rather than relying on donor sperm from another man. The research team, led by Professor Stefan Schlatt, at Muenster University in Germany, were able to grow sperm...

Scientists have developed a model that will enable them to investigate, for the first time, how human testes develop in baby boys while they are in the womb. Until now it has been impossible to study testicular development during pregnancy in humans and this discovery will enable researchers to understand the processes that can lead to the onset of testicular germ cell cancer (TGCC) in young adult life, and how factors, such as common environmental chemicals, might play a role. The research...

Scientists report that the use of scented creams and perfumes could increase the risk of unborn boys developing infertility later in life. The team of researchers at Edinburg University determined that building blocks for future reproduction were developed within a 12 week period during the pregnancy.  It is during this time they say developing infants may be more influenced by chemicals found in cosmetics. The research team led by Professor Richard Sharpe of the Medical Research...
