Does Cannabis Affect Sperm Quality? New Study Reveals Surprising Results

Healthcare, Medicine /

As cannabis becomes legal in many parts of the US, attention is turning from the ethics of its use to its health effects. Recent research indicates that smoking cannabis does not reduce sperm quality, contradicting findings from some previous studies. Study Analyzes Semen Samples from 921 Men to Assess Sperm Quality The study, conducted by […]

Scientists Observe Sperm Defying a Fundamental Law of Physics

Biology, Cell Biology /

According to a recent study, human sperm use their slender tails to navigate through thick fluids, appearing to defy Newton’s third law of motion. This research also examines the movement patterns of these sex cells alongside single-celled algae. Exploring Non-Reciprocal Interactions in Microscopic Swimmers Kenta Ishimoto, a mathematical scientist at Kyoto University, and his team

Ultrasound Boosts Dormant Sperm Activity by 266%

Medicine, Science /

Researchers have enhanced the movement of slow-moving sperm by as much as 266% through exposure to noninvasive 40-MHz ultrasound waves, prompting their motion. By examining the technique’s effects on individual sperm cells, the study paves the way for novel noninvasive fertility therapies. For the first time, scientists at Monash University in Australia have enclosed individual

Cell Phone Use May Potentially Affect Sperm Quality

Healthcare, Medicine /

Can the radiation emitted by mobile phones impact semen quality? Although various factors like environmental and lifestyle changes have been proposed to explain the decrease in semen quality observed over the last five decades, the role of mobile phones in this decline remains unproven. A collaborative team from the University of Geneva (UNIGE) and the

Amino Acid Alterations in Sperm Linked to Infertility

Biology, Cell Biology, Science /

Sperm play a vital role in creating new life, contributing half of the required genetic material for fertilization. Researchers at the University of Michigan are now delving into the molecular-level details of sperm formation, focusing on protamines—a unique group of proteins that package sperm DNA. Understanding the significance of protamines may shed light on male-factor
