Just because a sperm is a strong swimmer doesn't necessarily mean it has the right amount of DNA, Dr. Lisa Lee told Newsweek.

"These cells co-develop together, just like they would in an actual embryo, and establish that history of being neighbors," ...

Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...

Professor Im Joo Rhyu, director of the Korea University Graduate Program for Convergence & Translational Biomedicine and faculty member in the Department of Anatomy, recently led a study investigating ...

It's commonly thought that sperm "race" to the egg, with the winner fertilizing it. But is this really the case?

Initially, the pooled semen was diluted to a sperm density of 2 × 10 8 cells/mL using a standard semen diluent. Then, the diluted semen was placed into a 1,000 mL beaker filled with water at 30°C.

Two new landmark studies show how a seeming tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published March 3 as two papers in ...
