New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

Researchers at the UC Davis College of Biological Sciences have discovered that a little-known protein called ATF7IP2 helps to inactivate the X and Y chromosomes during cell divisions that lead to ...

Gene expression related to fertilization, sperm motility, and sperm structure in the testes of Tle6 -deficient mice showed an overall increase. Together, the findings of this study highlighted the ...

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 ...

Researchers from The University of Osaka find that CFAP91 and EFCAB5 proteins are crucial for sperm motility, and that loss of function of either of these proteins reduces male fertility in mice Osaka ...

Male and female reproductive systems allow human reproduction. Fertilisation occurs when a sperm and egg join to form an embryo. An embryo develops into an unborn baby in the uterus during pregnancy.
