Scientists have published the first meta-analysis to demonstrate declining sperm counts among men from South and Central America, Asia, and Africa. The international team was…
Research offers additional insights into the reproductive process. A team of scientists has discovered that the behavior of sperm cells is due, in part, to…
According to research conducted by the University of Pennsylvania, the enzyme DOT1L, a stem cell self-renewal factor, is necessary for mice to continue producing sperm…
Obese men can double their sperm count Men all throughout the globe are experiencing declining semen quality, which is commonly referred to as an outright…
A new sperm age measurement could predict pregnancy success Pregnancy, often known as gestation, is the period of time when one or more fetuses grow…
Testicles of most mammals are cooled in the scrotum, and elevated testicular temperatures lead to spermatogenesis failure and male infertility. A team of researchers led…
Scientists have traced the cause of increased numbers of mutations in children to a higher rate of random mutations in sperm cells of the biological…
A study led by researchers at the Universitat Autònoma de Barcelona (UAB) and the University of Kent uncovers how the genome three-dimensional structure of male…
Research in mice holds implications for childhood cancer survivors. Male testis tissue that is cryopreserved can be reimplanted after more than two decades and will…
According to a single-cell analysis of autopsied human testes, abnormalities associated with aging sperm cells may be exacerbated by elevated body mass index (BMI). The…
Dr. Wei Yan discovered a natural compound that exhibits almost ideal male contraceptive effects in pre-clinical studies. In a paper published by Nature Communications, The…
A discovery that blocks the normal transition of semen from a thick gel to a liquid shows promise for development of a new form of…
Reproductive Sciences experts at Cincinnati Children’s discover that the gene Cdc42 is required to support proper alignment and function of Sertoli cells. Scientists at Cincinnati…
Egg and sperm cell size evolved from competition. Limited resources drove gametes to differ vastly in size and number. In most living animals, egg cells…
Scientists no longer have to worry about their bottles of mouse sperm breaking in transit. Researchers in Japan have developed a way to freeze dry…
University of Toledo research shows the centriole’s role in sperm evolved from a shock absorber to a transmission system. Scientists at The University of Toledo…
Sperm size varies dramatically among different animal species. But why is sperm size so variable when they share the same job — to fertilize eggs?…
An alternative explanation of recent findings of declining sperm counts: normal, non-pathological variation. A new study from the Harvard GenderSci Lab in the journal Human Fertility,…
