Azoospermia is the medical condition of a man whose semen contains no sperm.
Deleted in azoospermia 1, also known as DAZ1, is a protein which in humans is encoded by the DAZ1 gene.
Deleted in azoospermia-like is a protein that in humans is encoded by the DAZL gene.
In biology, a gene is a sequence of DNA or RNA that codes for a molecule that has a function.
Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.
Protein–protein interactions (PPIs) are the physical contacts of high specificity established between two or more protein molecules as a result of biochemical events steered by electrostatic forces including the hydrophobic effect.
Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis.
The testicle or testis is the male reproductive gland in all animals, including humans.
The Y chromosome is one of two sex chromosomes (allosomes) in mammals, including humans, and many other animals.
